A Research Guide for
Scoliosis

The Adams forward bend test is the standard screening tool. The patient bends forward at the waist with arms hanging freely, and the examiner looks for asymmetry in the rib cage or lower back — a “rib hump” on one side indicates vertebral rotation, which is a hallmark of structural scoliosis.

A scoliometer is a small inclinometer placed on the back during the forward bend. It measures the angle of trunk rotation in degrees. A reading of 5–7 degrees or more typically triggers a referral for X-rays.

Important: These are screening tools, not diagnostic tools. A positive screening result means an X-ray is needed — it does not confirm scoliosis.

The definitive test for scoliosis is a standing posteroanterior (PA) full-spine X-ray. The Cobb angle is measured from this X-ray — it is the angle between the most tilted vertebrae at the top and bottom of the curve.

• 10–25° (mild): Observation with regular monitoring during growth.
• 25–45° (moderate): Bracing is recommended for skeletally immature patients.
• >45–50° (severe): Surgery is typically recommended.

A curve must measure at least 10 degrees to be classified as scoliosis. Curves under 10 degrees are considered normal spinal asymmetry.

EOS is a biplanar X-ray system that produces full-spine images with significantly less radiation than conventional X-rays — an important advantage because scoliosis patients need repeated imaging over years. EOS can also generate 3D reconstructions of the spine. It is preferred when available, particularly for children and adolescents who will have many follow-up images.

Two systems help measure skeletal maturity:

• Risser sign (0–5): Measures the ossification of the iliac crest (top of the hip bone) on the X-ray. Risser 0 means no ossification has appeared on the iliac apophysis (maximum growth remaining); Risser 5 means the growth plate is fully fused (growth is complete). The higher the Risser number, the less growth remaining and the lower the risk of curve progression.
• Sanders classification (1–8): Uses a hand X-ray (bone age) to more precisely stage skeletal maturity. Particularly useful for determining VBT candidacy (Sanders stage 4–6 is the typical window).

Other indicators include menarche timing for girls (curves are at highest risk of progression before and during the first year after menarche) and the status of the triradiate cartilage at the hip.

The risk that a curve will worsen depends on several factors working together:

• Curve size: Larger curves at detection have a higher risk of progressing further.
• Growth remaining: The more growth remaining (lower Risser, pre-menarchal), the higher the risk.
• Sex: Girls are more likely than boys to have curves that progress to the treatment threshold.
• Curve pattern: Thoracic curves and double curves tend to progress more than single lumbar curves.

A high-risk profile — for example, a girl who is pre-menarchal with a Risser 0 and a Cobb angle of 25–35 degrees — has roughly a 68% chance of progression. This is the patient who benefits most from timely bracing.

MRI is not routine for typical adolescent idiopathic scoliosis but is indicated in specific situations:

• Left thoracic curves (unusual pattern that may suggest an underlying cause)
• Early-onset scoliosis (before age 10)
• Rapid progression (more than 1 degree per month)
• Neurological signs (weakness, numbness, abnormal reflexes, bowel/bladder changes)
• Congenital vertebral anomalies
• Severe pain out of proportion to the curve
• Night pain or pain that wakes from sleep (a red flag for a possible spinal tumor such as osteoid osteoma)

An MRI looks for underlying causes such as a tethered spinal cord, syrinx (fluid-filled cavity in the cord), Chiari malformation, or spinal tumors.

Scoliosis monitoring involves repeated X-rays, and cumulative radiation exposure is a legitimate concern. Several strategies minimize radiation:

• PA (posteroanterior) rather than AP imaging: The X-ray beam enters through the back and exits through the chest, reducing breast tissue radiation by up to 90%.
• EOS low-dose imaging when available: Uses significantly less radiation than conventional X-rays.
• Monitoring schedule adjusted to risk: During rapid growth, X-rays every 4–6 months. After skeletal maturity or curve stability, intervals can lengthen.
• Keeping a radiation log: Ask the clinic to note the dose from each imaging session so cumulative exposure can be tracked.

• What is the current Cobb angle, and has it changed since the last measurement?
• What is the Risser sign? How much growth is remaining?
• What is the risk that this curve will progress based on my child’s specific factors?
• Is an MRI needed, or is this a straightforward idiopathic curve?
• Does this facility have EOS imaging to reduce radiation exposure?
• How often will we need X-rays, and is there a way to minimize radiation?
• At what point would you recommend starting bracing?
• Should we get a bone age (hand X-ray) to better assess skeletal maturity?

• Boston brace (TLSO): The most commonly prescribed brace in North America and the most studied in clinical trials. A rigid plastic brace custom-molded to the patient, applying corrective forces through pads.
• Rigo-Chêneau brace: The predominant brace in Continental Europe. Uses a three-dimensional correction approach based on the Schroth classification of curve patterns.
• Providence brace: A night-time-only brace that overcorrects the curve while the patient sleeps. An option for select mild-to-moderate curves, reducing the burden of full-time wear.
• Charleston bending brace: Another night-time option that bends the patient into the correction while sleeping.

The choice of brace depends on curve type, geographic practice patterns, and the experience of the orthotist (brace maker). What matters most is that the brace achieves good in-brace correction (target: more than 50% curve reduction on the in-brace X-ray) and that the patient wears it enough hours.

Brace technology is evolving. CAD/CAM braces use 3D body scanning to create a digital model, which can then be carved or 3D-printed into a custom brace. The potential advantages include better fit, lighter weight, and improved cosmetic design — all of which may improve compliance in self-conscious adolescents.

Smart brace technology uses temperature and pressure sensors embedded in the brace to objectively measure wear time. This replaces reliance on self-reported compliance, gives the clinical team real data to optimize treatment, and can motivate teens by showing them their progress. A clinical trial (NCT03365804) tested a new 3D-printed brace design (this trial was terminated early in 2023).

While promising, large-scale clinical validation of 3D-printed braces is still limited. Conventional braces remain the established standard.

Most bracing protocols require 16–23 hours per day of wear. The BrAIST trial demonstrated a clear dose-response — 13 hours per day was the minimum associated with benefit, and more hours produced better results. The target for most full-time protocols is 18 hours per day.

Bracing continues until skeletal maturity, typically Risser 4 or approximately 2 years after the first menstrual period. Weaning is then done gradually over 6–12 months rather than stopping abruptly.

The first in-brace X-ray is usually taken 4–6 weeks after fitting. A good result is more than 50% correction of the curve in the brace. If correction is poor, the brace may need adjustment.

• School: A well-fitting brace can be worn under clothing. Most teachers do not need to know unless the student wants to tell them. Extra time between classes may be helpful.
• Sports: Many sports can be continued while bracing. Swimming is often done during brace-off time. Contact sports may require removal. Discuss specific activities with the doctor.
• Sleep: An adjustment period of 2–4 weeks is normal. A firm mattress helps. Some patients find it comfortable to sleep on their side with a pillow between their knees.
• Skin care: Wear a snug cotton T-shirt or tank top under the brace to reduce irritation. Check for red spots daily — persistent red marks after 20 minutes out of the brace may indicate a fit problem.
• Clothing: Loose-fitting shirts and pants one size up accommodate the brace. Many teens find that longer tops and stretchy waistbands work well.
• Body image: Feeling self-conscious is normal and valid. Connecting with other teens who wear braces — through groups like Curvy Girls — can make a real difference.

Brace compliance is one of the biggest challenges in scoliosis treatment. The brace only works when it is worn. Practical strategies that help:

• Frame the brace as a positive tool, not a punishment. It is protecting the spine during a critical window.
• Set clear expectations from the start — the wear schedule is not negotiable, but flexibility on which hours are “off” is reasonable.
• Let the teen have some control: choosing the brace color, deciding when to take the allowed hours off, picking comfortable clothing.
• If smart sensors are available, use the data constructively, not punitively. Celebrate good wear weeks.
• Address emotional struggles early. If the teen is resistant, ashamed, or depressed about the brace, counseling or peer support (Curvy Girls, scoliosis camps) can help enormously.
• Maintain open communication with the orthotist — a poorly fitting brace is painful and will not be worn. Adjustments should be made promptly.

• What type of brace are you recommending and why?
• How many hours per day should the brace be worn?
• What does the in-brace X-ray show — is the correction at least 50%?
• Is this orthotist experienced with scoliosis braces specifically?
• Are smart sensors available to track wear time?
• Would a night-time brace be appropriate for this curve?
• What sports and activities can continue during bracing?
• How long will bracing be needed, and when do we start weaning?
• Should scoliosis-specific exercises be combined with the brace?

The Schroth method uses three-dimensional autocorrection — exercises that address the curve in all three planes of the body (side-to-side, front-to-back, and rotational). A key technique is rotational breathing, which directs airflow into the concave side of the rib cage to expand collapsed areas.

Each patient’s exercise program is tailored to their specific curve pattern. Exercises are performed daily at home after being taught by a certified Schroth therapist. The approach builds muscle awareness and postural habits that work against the curve throughout the day.

SEAS uses functional autocorrection — the patient learns to actively correct their spinal alignment and then maintains that corrected position while performing progressively challenging exercises. The goal is to integrate the corrected posture into daily activities.

SEAS was developed at ISICO (Italian Scientific Spine Institute) and emphasizes self-correction as the core principle, with exercises building on that foundation.

The evidence for scoliosis-specific exercises has strengthened in recent years:

• A 2025 Bayesian network meta-analysis found that Schroth and PSSE (physiotherapeutic scoliosis-specific exercises) significantly improved Cobb angle, trunk rotation, and quality of life compared with controls.
• A 2024 prospective controlled study showed that PSSE-Schroth as the exclusive treatment reduced progression risk for curves under 25 degrees during early rapid growth.
• A 2024 randomized controlled trial found that supervised Schroth exercises combined with bracing improved curve severity and quality of life in patients aged 10–17 compared with bracing alone.

The effect sizes are modest — typical Cobb angle reductions of 2–5 degrees — but the improvements in trunk rotation, cosmetic appearance, and quality of life are meaningful. The SOSORT (Society on Scoliosis Orthopaedic and Rehabilitation Treatment) consensus recommends SSE for mild curves and as a complement to bracing.

The most common barrier to scoliosis-specific exercises is finding a properly trained therapist. Key points:

• Look for certification specifically in the Schroth method (e.g., through the Barcelona Scoliosis Physical Therapy School or the Schroth Best Practice Academy) or SEAS training through ISICO.
• General physical therapists, personal trainers, and chiropractors are not trained in these methods unless specifically certified.
• In areas without certified therapists, tele-rehabilitation platforms are an emerging option — remote supervision of exercises by trained therapists.
• The SOSORT website and the Scoliosis Research Society can help locate qualified providers.

• Would scoliosis-specific exercises be appropriate for this curve?
• Should exercises be used alone, or combined with bracing?
• Can you recommend a certified Schroth or SEAS therapist in our area?
• How often should the exercise program be supervised versus done at home?
• What results can we realistically expect from exercises alone?
• Is tele-rehabilitation an option if there is no certified therapist nearby?

The surgeon makes an incision along the back of the spine and attaches metal rods and screws (pedicle screws) to the vertebrae involved in the curve. The rods are carefully contoured to the desired correction and then attached to the screws, gradually pulling the spine into a straighter alignment. Bone graft material is placed along the spine to fuse the vertebrae together permanently.

The surgery typically involves 10–12 vertebral levels, depending on the curve pattern. The Lenke classification system helps the surgeon plan exactly which levels to fuse and which to leave free.

Potential complications to discuss with the surgical team include:

• Infection (1–2%): Treated with antibiotics, sometimes requiring implant removal or washout.
• Proximal junctional kyphosis (PJK, 5–20%): A rounding of the spine just above the fusion, sometimes requiring revision surgery.
• Pseudarthrosis: Failure of the bone to fully fuse, potentially requiring a second surgery.
• Neurological injury (<1%): Very rare with modern neuromonitoring but possible. This is why choosing an experienced center matters.
• Implant failure: Rod breakage or screw loosening, though uncommon with modern instrumentation.

Robotic-assisted pedicle screw placement (systems include ExcelsiusGPS and Mazor X) is increasingly used in scoliosis surgery. Early case series with ExcelsiusGPS report high screw accuracy and low complication rates, though data is limited to small series from specialized centers. All robotic systems demonstrate higher screw placement accuracy than traditional fluoroscopy-guided freehand techniques.

Robotic assistance is especially valuable in scoliosis, where deformed anatomy makes accurate screw placement more challenging. Reduced radiation exposure to the surgical team is an additional benefit.

Not all centers have robotic systems. Excellent results are also achieved by experienced surgeons using conventional techniques with intraoperative CT navigation.

• Hospital stay: Typically 3–5 days. Patients are up and walking within 1–2 days.
• Return to school: Usually 4–6 weeks after surgery.
• Light activity: Walking and gentle movement immediately; gradually increasing over weeks.
• Return to most sports: Typically 6–12 months. Contact sports are the last to be cleared.
• Full recovery: Most patients feel fully recovered by 6–12 months, though the bone fusion continues to mature for up to a year.

The fused segment of the spine will not move, but because the fusion typically involves the thoracic spine (mid-back), most patients retain good overall spinal mobility and can bend, twist, and participate in nearly all activities.

• How many scoliosis surgeries do you perform per year?
• Which levels will be fused, and how much correction do you expect?
• Will intraoperative neuromonitoring be used?
• Is robotic-assisted or navigation-guided screw placement available?
• What is your complication rate for this procedure?
• What restrictions will there be after surgery, and for how long?
• When can my child return to school and to sports?
• What does long-term follow-up look like after fusion?
• Is this curve a candidate for VBT instead of fusion?

The surgery is performed thoracoscopically (through small incisions in the chest, without opening the back). Screws are placed into the vertebral bodies on the convex (outer) side of the curve, and a flexible polyethylene cord connects the screws under tension. As the child continues to grow, the tethered side grows more slowly while the untethered side catches up, gradually correcting the curve through growth modulation.

This is fundamentally different from fusion: the spine remains flexible, motion is preserved, and growth continues. The correction is a partnership with the body’s own growth rather than a mechanical straightening.

VBT is appropriate for a specific subset of patients:

• Skeletally immature: Must have significant growth remaining (typically Sanders stage 4–6 or Risser 0–2). Growth is what drives the correction.
• Flexible curves: The curve should correct by at least 50% on bending X-rays.
• Cobb angle 30–65 degrees: Moderate-to-severe curves large enough to warrant surgery but flexible enough for tethering to work.
• Thoracic curves preferred: The thoracoscopic approach works best for thoracic curves.

VBT is not appropriate for all patients who would otherwise need fusion. Rigid curves, very large curves, lumbar curves, and skeletally mature patients are generally not candidates. Careful evaluation by a surgeon experienced with VBT is essential.

VBT is a promising but still-evolving procedure. The honest picture from current data:

• Early correction is typically 50–60% of the curve, comparable to fusion.
• A study with at least 5 years of follow-up (74 patients) found 66% had radiographically suspected tether breakage after 5 years, 13.5% ultimately required conversion to fusion, and the overall reoperation rate was 21.6%.
• A separate study found 49% tether breakage, with single-cord constructs having a 60% breakage rate.
• The Scoliosis Research Society (May 2023) described VBT as potentially effective but under active investigation.

• Is my child a good candidate for VBT based on skeletal maturity, curve size, and flexibility?
• How many VBT procedures have you performed, and what are your outcomes?
• What is the tether breakage rate in your experience?
• What happens if the tether breaks — does it always mean a second surgery?
• What is the risk of overcorrection as the child continues to grow?
• If VBT is not ideal, would you recommend fusion instead, or is there another option?
• Is your center participating in any VBT outcome registries or studies?

Traditional growing rods are attached to the spine above and below the curve and periodically lengthened through a small surgical procedure every 6–8 months. Each lengthening is a relatively minor operation, but the cumulative burden of repeated surgeries over years is significant.

MAGEC rods represent a major advance: the rods contain an internal magnet that can be lengthened non-invasively in the clinic by placing a magnet on the skin over the rod. This eliminates the repeated surgeries required by traditional growing rods, though the initial implantation and final conversion to fusion still require surgery.

MAGEC rods have reduced the number of unplanned returns to the operating room compared with traditional growing rods.

• VEPTR (Vertical Expandable Prosthetic Titanium Rib): Used for thoracic insufficiency syndrome associated with severe scoliosis. Attaches to the ribs and spine to expand the chest while controlling the curve. Primary Children’s Hospital has significant experience with VEPTR (86-patient program).
• Mehta casting: For infantile scoliosis (under 3 years), serial body casts applied under anesthesia can sometimes resolve the curve entirely. This is most effective for flexible curves detected early. Primary Children’s Hospital offers this technique.

ApiFix is a posterior dynamic correction device that aims to provide moderate curve correction with a shorter fusion segment than traditional PSF. Data show 46% major curve correction (average from 47 degrees to 25 degrees) with 82% of patients achieving a final Cobb angle of 30 degrees or less, preserving a degree of spinal motion not possible with traditional fusion. It is an option for moderate, single Lenke 1 or 5 curves, though concerns remain about implant breakage in some cases.

• What is the best growth-sparing option for my child’s specific situation?
• Are MAGEC rods available, and would they reduce the number of surgeries needed?
• If Mehta casting is an option, how many casts are typically needed and over what timeframe?
• When will definitive fusion eventually be performed?
• What is the impact on lung development if we do not treat this curve now?
• Does this center have experience treating early-onset scoliosis specifically?
• Would a referral to Primary Children’s Hospital or Shriners Children’s be appropriate?

Scoliosis diagnosed before age 10 carries additional concerns because the lungs and thorax are still developing. A severe curve that limits chest expansion can lead to thoracic insufficiency syndrome — the lungs cannot develop to their full capacity.

Treatment follows a careful ladder: observation for mild curves, serial Mehta casting for progressive infantile curves, bracing when appropriate, and growth-sparing surgery (growing rods, MAGEC rods, or VEPTR) when the curve progresses despite conservative measures. The goal throughout is to control the curve while allowing maximum lung and skeletal growth, delaying definitive fusion as long as possible.

Adult scoliosis falls into two categories: adult idiopathic (a curve that has been present since adolescence and may be progressing) and degenerative (a new curve developing from disc and joint degeneration, typically in the lumbar spine).

The treatment goals in adults are fundamentally different from adolescents. The focus is on pain, function, and quality of life rather than curve magnitude. Treatment follows this sequence:

• Physical therapy and core strengthening: First-line treatment for most adults. Scoliosis-specific exercises can help.
• Pain management: Anti-inflammatory medications, epidural steroid injections, nerve blocks.
• Minimally invasive surgery (LLIF, OLIF): Emerging lateral approaches that achieve meaningful correction with less surgical morbidity. A 2025 systematic review found LLIF achieves an average 9.5-degree Cobb reduction.
• Major deformity correction surgery: Reserved for severe disability, progressive neurological deficits, or intractable pain that has not responded to conservative treatment. Adult deformity surgery carries higher complication rates (30–40% minor, 10–15% major) and requires careful preoperative assessment of frailty and realistic goal-setting.

Neuromuscular scoliosis develops in patients with conditions affecting the muscles or nervous system — cerebral palsy, Duchenne muscular dystrophy, spinal muscular atrophy (SMA), and spina bifida, among others. These curves tend to be long, C-shaped, progressive, and can cause pelvic obliquity (tilting of the pelvis) that affects sitting balance and wheelchair positioning.

An important recent development: disease-modifying drugs for SMA (nusinersen, risdiplam, onasemnogene) may reduce scoliosis progression in SMA patients by improving muscle function.

Surgical treatment often requires fusion extending to the pelvis and carries higher complication rates (10–25%) than AIS surgery. A multidisciplinary team — including neurology, pulmonology, and rehabilitation — is essential for managing these complex patients.

Congenital scoliosis results from vertebral malformations present at birth — such as hemivertebra (a wedge-shaped vertebra) or an unsegmented bar (vertebrae fused together on one side). The natural history varies greatly depending on the specific defect type.

Because congenital scoliosis is associated with other birth abnormalities, every child diagnosed should be evaluated with an echocardiogram (20% have cardiac anomalies), a renal ultrasound (25% have kidney anomalies), and an MRI of the entire spine (20–40% have intraspinal anomalies such as a tethered cord or diastematomyelia).

Surgical options include hemivertebra excision, in situ fusion, and growth-sparing constructs, depending on the defect and the child’s age.

• Which type of scoliosis does my child have, and how does that affect the treatment plan?
• For early-onset: what is the impact on lung development, and how are you monitoring that?
• For adult scoliosis: is conservative treatment likely to be sufficient, or is surgery on the horizon?
• For neuromuscular scoliosis: how does the underlying condition affect surgical planning and risk?
• For congenital scoliosis: have all the associated screening tests been done (echo, renal ultrasound, MRI)?
• Is a multidisciplinary team involved in the treatment plan?

One of the most common fears — for both patients and parents — is that scoliosis means giving up sports and physical activities. In reality:

• During bracing: Most sports can continue. Swimming is often done during brace-off time. High-impact contact sports may require discussion with the doctor, but many braced teens participate fully in athletics.
• After fusion surgery: Return to light activity within weeks. Most sports, including competitive athletics, resume within 6–12 months. Contact sports are typically the last to be cleared. Many athletes return to the same level of performance they had before surgery.
• After VBT: Activity restrictions are typically 6–12 weeks, with gradual return to all activities.

Regular exercise is encouraged at all stages of scoliosis management. Swimming, in particular, is excellent for building core and back strength without high impact.

A brace only works if it’s worn — and the research is clear that hours of wear, more than the brace design, determine success. The challenge is rarely the medicine; it’s making the brace livable. Practical tips that help real families:

• Clothing: A snug seamless cotton undershirt worn under the brace prevents rubbing and absorbs sweat. Sizing tops one size up, choosing patterned or looser fabrics, and layering all make the brace far less visible than teens fear.
• Skin care: Check skin daily for redness; persistent red marks that don’t fade within ~30 minutes of brace-off mean the fit needs adjusting — call the orthotist rather than enduring it. Keep skin clean and dry; avoid lotions under the brace (they soften skin and worsen rubbing).
• Sleep: Most braces are worn overnight. A firmer mattress, a thin pillow, and a week or two to adjust usually solve early sleep difficulty. Night-only braces exist for some milder curves.
• Building wear time: Ramp up gradually over the first 1–2 weeks rather than jumping to full-time. Anchor wear to routines (home, homework, sleep) and use the brace-off hours for sports and showering.
• Tracking: Many braces now include a small temperature sensor that records wear hours. Rather than feeling “watched,” many families find it helps — it turns an abstract goal into concrete feedback and credit for the hours put in.
• Activity: You can stay active in a brace; most teens take it off for sports and PE per their doctor’s plan. Bracing does not mean sitting on the sidelines.

If the brace is genuinely intolerable — not just inconvenient — tell the team. A brace that doesn’t fit won’t be worn, and won’t work; the fix is adjustment, not endurance.

Not all scoliosis is found in adolescence. Many adults learn they have a curve later in life — either a curve that began in their teens and was never treated, or a new “degenerative” curve that develops as the discs and joints of the spine wear with age. Adult scoliosis is genuinely different from the adolescent kind, and understanding that difference helps set expectations:

• The goal shifts from the curve to how you feel. In adults, treatment is driven by pain, function, and quality of life — not by the size of the curve on its own. A large curve that doesn’t bother you may need only monitoring, while a smaller curve causing leg pain or imbalance may warrant more.
• Most adults never need surgery. First-line care is non-surgical: physical therapy and core strengthening, staying active, weight management, targeted injections for nerve-related leg pain, and medications for pain. Many people do well for years this way.
• Surgery is reserved for specific problems — nerve compression causing weakness or relentless leg pain, pain that hasn’t responded to thorough non-surgical care, or a spine that is becoming unbalanced (leaning forward or to the side). Adult spine surgery is bigger and carries more risk than adolescent surgery, so it’s a carefully shared decision.
• What matters most is alignment, not just the angle. Surgeons focus on keeping your head balanced over your pelvis (“sagittal balance”); restoring that balance is what most improves function.

If you’re an adult newly diagnosed, a reasonable first step is evaluation by a spine specialist who treats adult deformity, an honest trial of non-surgical care, and a clear conversation about what is actually causing your symptoms — because in adults the curve and the symptoms don’t always match.

Women with spinal fusion for scoliosis generally have favorable pregnancy and delivery outcomes. Studies show that fusion does not prevent normal pregnancy, vaginal delivery, or epidural anesthesia in most cases (though the anesthesiologist needs to know the fusion levels in advance). Discuss your surgical history with your obstetrician early in pregnancy or during preconception planning.

The psychosocial impact of scoliosis — particularly on adolescents — is real and should not be minimized. Common concerns include:

• Body image and self-consciousness about the curve, rib prominence, or brace
• Feeling different from peers during a developmental period when fitting in matters intensely
• Anxiety about whether the curve will worsen or whether surgery will be needed
• Frustration with the constraints of bracing
• Fear about surgery and its aftermath

These feelings are valid and treatable. Peer support groups (Curvy Girls is specifically for adolescent girls with scoliosis), school counselors, and mental health professionals with experience in chronic conditions can all help. Do not wait for emotional distress to become severe before seeking support.

When a child is diagnosed with scoliosis, parents often feel worry, guilt (“did I miss it? did I cause it?”), and pressure to make the right decisions. A few things help:

• You did not cause this. Adolescent idiopathic scoliosis is not caused by backpacks, posture, sports, or anything you did or didn’t do. Genetics play a role, but it is no one’s fault.
• Make the brace the team’s job, not a battle. Bracing works only if it’s worn, and nagging tends to backfire. Frame it as a time-limited project with a clear end point, let your teen own as much of it as possible, and use the brace’s wear-time data as neutral feedback rather than a verdict. Celebrate the hours, not just the X-ray.
• Protect normal life. Keep your child in sports, friendships, and activities. Scoliosis treatment is designed to fit around a full adolescence — the goal is a normal life, and treating your child as fragile can do more harm than the curve.
• Mind the emotional side. Body image and feeling different are real for braced teens. Watch for withdrawal, sadness, or anxiety, normalize talking about it, and connect your child with peer support (such as Curvy Girls) or a counselor early — before distress builds.
• Be an informed partner. Learn the three numbers that drive decisions (curve size, growth remaining, curve pattern), keep a copy of X-ray reports, and bring written questions to visits. Understanding the plan reduces everyone’s anxiety.
• Take care of yourself too. Your steadiness is part of what helps your child cope. It’s okay to seek your own support.

Most children with scoliosis grow into healthy, active adults. Your calm, informed support through the treatment years is one of the most valuable things you can offer.

Scoliosis care revolves around a few numbers from your X-rays. Knowing what they mean helps you follow your own (or your child’s) progress:

• Cobb angle is the size of the curve in degrees — the single most important number. Roughly: under 25° is usually watched; 25–45° in a growing child is the bracing range; above 45–50° is when surgery is discussed. A change of about 5° or more between visits counts as real progression (smaller changes can just be measurement variation).
• Risser sign (0–5) estimates how much growing is left, based on a growth center on the pelvis. Risser 0–2 means lots of growth remaining (higher risk of the curve worsening, and the window when bracing works); Risser 4–5 means growth is nearly finished (curves are much less likely to progress, and bracing no longer helps).
• Curve pattern and flexibility — where the curve is, whether there are one or two curves, and how much it straightens on bending X-rays — guides which treatment fits and, if surgery is needed, how much of the spine is involved.

Put together, these explain why two people with the same Cobb angle can get very different advice: a 30° curve in a young, fast-growing child is treated urgently, while the same 30° curve in someone who has finished growing may simply be monitored. A useful question at each visit: “What’s my Cobb angle and Risser sign now, and is the curve stable or changing?”

• A letter from the doctor to the school explaining the condition and any accommodations needed (extra time between classes, modified PE activities, permission to leave class for brace adjustment)
• A 504 plan or individualized education plan (IEP) if the condition affects school participation
• Permission to carry a water bottle (staying hydrated is important during bracing)
• A comfortable chair or cushion if sitting for long periods is uncomfortable
• After surgery: a plan for homebound instruction during the 4–6 week recovery period and a gradual return to full schedule

• Bring all X-rays and imaging (on disc or through your portal), especially if seeing a new provider.
• Write down your questions in advance. Appointments move quickly, and it is easy to forget important questions in the moment.
• Track symptoms between visits: pain location and intensity, activity limitations, brace wear hours, exercise compliance.
• Bring a second person to take notes. Two sets of ears catch more than one.
• Ask for a summary. At the end of each appointment, ask the doctor to summarize the current status, any changes to the plan, and when to come back.

Good questions help you understand the plan and feel like a partner in it. Useful ones at different stages:

At diagnosis:

• What is my (or my child’s) Cobb angle, and what type of scoliosis is it?
• How much growing is left (Risser sign / skeletal maturity), and what does that mean for the risk of the curve getting worse?
• Does this curve need treatment now, or monitoring — and how often should we re-check?
• Should siblings or my other children be checked?

If bracing is recommended:

• What type of brace, how many hours a day, and for how long?
• What in-brace correction did the first X-ray show, and is the fit good?
• Can we use a wear-time sensor so we know how it’s going?
• Can my child keep doing sports and activities?

If surgery is discussed:

• Why now, and what happens if we wait?
• How many levels would be fused, and how will that affect movement?
• What are the specific risks at your center, and how many of these surgeries do you do a year?
• Is vertebral body tethering (VBT) an option for us, and what are its trade-offs?
• What does recovery look like, and when can normal activities and sports resume?

It’s always reasonable to ask for a second opinion at an experienced scoliosis center, especially before surgery.

• Sudden severe back pain
• Weakness or numbness in the legs
• Difficulty walking or changes in gait
• Loss of bladder or bowel control
• After surgery: fever, wound drainage, increasing pain, or new neurological symptoms

These may indicate a neurological emergency (spinal cord compression) requiring urgent evaluation. Do not wait for the next scheduled appointment.

Scoliosis management does not end at skeletal maturity or after surgery. Long-term follow-up is important for:

• After bracing: Monitoring curve behavior after brace discontinuation. Some curves can progress slowly even after skeletal maturity, particularly curves above 30 degrees at the completion of bracing.
• After fusion: Monitoring for adjacent segment degeneration (wear on the discs above and below the fusion), proximal junctional kyphosis, and implant-related issues. Follow-up at 1, 2, 5, and 10 years is typical.
• After VBT: Monitoring for tether breakage, overcorrection, and curve behavior as growth completes.

• Normalize the experience. Scoliosis is common. Most children with scoliosis do not need surgery and lead completely normal lives.
• Balance vigilance with calm. Follow the monitoring schedule carefully, but do not let anxiety about the curve dominate family life.
• Advocate effectively. Know the numbers (Cobb angle, Risser sign) and bring your organized records to every appointment. Prepared families get better care.
• Support independence. Adolescents with scoliosis should gradually take ownership of their own care — understanding their condition, participating in appointments, managing their brace and exercise routine.
• Take care of yourself. Managing a child’s chronic condition is stressful. Seek your own support when you need it.
• Prepare for surgery if it comes. Tour the hospital, meet the surgical team beforehand, arrange school accommodations, prepare the home (raised toilet seat, grabber tool, recovery supplies), and plan for 4–6 weeks of homebound recovery.

Clinical trial information is available at ClinicalTrials.gov. Discuss with your doctor whether any trial is appropriate for your situation.

Research has identified over 21 genetic loci associated with scoliosis, including LBX1, PAX1, GPR126, GDF6, and BNC2. Novel loci GAK and KLF12 were identified in 2025–2026 studies. However, early prediction models explain only about 7.9% of variance in specific populations — modern polygenic scores explain somewhat more but remain insufficient for clinical use.

Machine learning algorithms that combine genetic data with clinical features (initial Cobb angle, skeletal maturity, curve pattern) may eventually allow personalized prediction of which children are most likely to need treatment, reducing unnecessary monitoring for low-risk patients. This remains a research goal, not a clinical tool.

The standard measurement of scoliosis curve severity, expressed in degrees. Measured on a standing posteroanterior (PA) full-spine X-ray by drawing lines along the endplates of the most tilted vertebrae at the top and bottom of the curve. A Cobb angle of 10° or more defines scoliosis. Mild: 10–25°. Moderate: 25–45°. Severe: >45–50°. A change of more than 5° between visits is considered clinically significant progression.

A grading system (0 through 5) that measures skeletal maturity by assessing the ossification (hardening) of the iliac apophysis — the growth plate along the top of the hip bone, visible on a standard scoliosis X-ray.

• Risser 0: No ossification visible. Maximum growth remaining. Highest risk of curve progression.
• Risser 1: Ossification of the lateral 25% of the iliac apophysis. Significant growth remaining.
• Risser 2: Ossification of 25–50%. Active growth phase; bracing is still effective.
• Risser 3: Ossification of 50–75%. Growth slowing but not complete.
• Risser 4: Ossification of 75–100%, but apophysis not yet fused to the ilium. Near skeletal maturity; bracing is typically weaned.
• Risser 5: Complete fusion of the apophysis to the ilium. Skeletal maturity is reached. Growth is complete and the risk of further progression is low (though curves above 30° may still progress slowly in adulthood).

The standard classification system for adolescent idiopathic scoliosis, used by surgeons to plan which vertebral levels to fuse. The system categorizes curves into 6 main types based on the location and flexibility of the major and minor curves, combined with a lumbar modifier (A, B, or C) and a sagittal thoracic modifier (minus, normal, or plus). Understanding your Lenke type helps explain why the surgeon recommends fusing specific levels.

The most common form of scoliosis, accounting for approximately 80% of all cases. “Adolescent” refers to onset during the growth spurt (ages 10–18). “Idiopathic” means no identifiable underlying cause — the spine curves for reasons that are not fully understood, though genetics play a significant role. AIS is more common in girls who progress to needing treatment.

A fusionless surgical technique that received an FDA Humanitarian Device Exemption in 2019. Screws are placed into the vertebral bodies on the convex (outer) side of the curve and connected by a flexible polyethylene cord under tension. As the child grows, the tethered side grows more slowly while the untethered side catches up, gradually correcting the curve through growth modulation. VBT preserves spinal motion and growth but has a meaningful reoperation rate (approximately 20%) and limited long-term data beyond 5 years.

The gold standard surgical treatment for severe scoliosis (Cobb >45–50°). Metal rods and pedicle screws are attached to the vertebrae to correct the curve, and bone graft material is placed to permanently fuse the involved vertebrae together. Achieves 60–70% curve correction. The fused segment no longer moves, but most patients retain good overall spinal mobility because fusion typically involves the thoracic (mid-back) region.

A scoliosis-specific physiotherapy approach developed in Germany by Katharina Schroth. Uses three-dimensional autocorrection exercises that address the curve in all three planes of the body — side-to-side, front-to-back, and rotational. A signature technique is rotational breathing, which directs airflow into the concave (collapsed) side of the rib cage. Each exercise program is tailored to the patient’s specific curve pattern. Requires a certified Schroth therapist. Not the same as general physical therapy.

A scoliosis-specific exercise method developed at ISICO (Italian Scientific Spine Institute). The core principle is functional autocorrection — the patient learns to actively correct their spinal alignment and then maintains that corrected position while performing progressively challenging exercises. The goal is to integrate corrected posture into daily life. Like Schroth, SEAS requires specifically trained therapists and is distinct from general physical therapy.

The normal front-to-back curvature of the thoracic spine (mid-back), which curves outward (convex posteriorly). Normal thoracic kyphosis ranges from 20–45°. Excessive kyphosis (>45°, sometimes called Scheuermann’s kyphosis) produces a “round back” appearance. In scoliosis surgery, the sagittal thoracic kyphosis is measured and classified as part of the Lenke system to guide surgical planning.

The normal front-to-back curvature of the lumbar spine (lower back) and cervical spine (neck), which curves inward (concave posteriorly). Normal lumbar lordosis ranges from 40–60°. Maintaining proper lordosis is an important goal in scoliosis surgery, as loss of lumbar lordosis can cause pain and forward-leaning posture (flatback syndrome).

Refers to the junction between the thoracic (mid-back) and lumbar (lower back) spine, roughly at the T12–L1 vertebral level. A thoracolumbar curve is a scoliosis curve centered at this junction. Thoracolumbar curves can be treated with bracing or surgery depending on severity, and have different natural history and treatment considerations than purely thoracic or lumbar curves.

A scoliosis that develops in adulthood (typically after age 40–50) due to age-related degeneration of the intervertebral discs and facet joints, most commonly in the lumbar spine. Distinct from adult idiopathic scoliosis (a curve present since adolescence that persists or worsens). Treatment goals focus on pain management, functional improvement, and quality of life rather than curve correction. Conservative treatment (physical therapy, injections, medication) is first-line; surgery is reserved for severe pain or neurological compromise unresponsive to conservative measures.

Growth modulation is the principle behind VBT and other fusionless approaches: selectively slowing growth on one side of the spine so the other side can catch up, gradually correcting the curve using the body’s own growth. Active research directions include:

• Guided posterior vertebral growth modulation: Researchers are exploring techniques that apply growth-modulating forces from the posterior (back) side of the spine rather than the anterior (front) approach used in VBT. Posterior approaches could potentially avoid the thoracoscopy required for VBT and extend eligibility to lumbar curves. These remain in early-stage development.
• Staple-based growth modulation (vertebral body stapling): Shape-memory alloy staples placed across vertebral growth plates to selectively restrict growth. Earlier clinical experience showed variable results, and research continues to refine patient selection criteria and staple design.
• Biodegradable implants: Investigational devices that provide growth modulation during the critical growth period and then gradually resorb, potentially eliminating the need for implant removal or the long-term concerns associated with permanent hardware.

Growth modulation is conceptually appealing because it works with the body rather than against it. The challenge is achieving reliable, predictable correction — the variables of individual growth rate, growth remaining, and curve flexibility make outcomes less predictable than fusion.

ApiFix is a posterior dynamic correction device designed for moderate, flexible, single-curve AIS (Lenke type 1 or 5). Unlike traditional fusion, it aims to achieve correction with a short fusion segment, preserving more spinal motion.

• Clinical data show an average major curve correction of 46% (from approximately 47° to 25°), with 82% of patients achieving a final Cobb angle of 30° or less.
• The device involves a ratchet-based elongation mechanism activated by patient-performed exercises during the postoperative period.
• Advantages: shorter operative time, less blood loss, shorter fusion segment, and faster recovery compared with full-length PSF.
• Concerns: device breakage has been reported in some series, and the device is not suitable for all curve types or magnitudes.
• Ongoing research is evaluating long-term durability and defining optimal patient selection criteria.

Vertebral body tethering continues to evolve as surgeons and device manufacturers address the limitations identified in early-generation constructs:

• Improved cord materials: Research into stronger, more durable polyethylene cords and alternative materials aims to reduce the tether breakage rate (currently reported at 49–66% at 5 years in some series). Next-generation cords may offer better fatigue resistance while maintaining the flexibility needed for growth modulation.
• Dual-cord constructs: Studies have found that single-cord constructs have a 60% breakage rate. Dual-cord systems (two parallel cords) may provide redundancy and distribute mechanical stress, potentially reducing breakage. This is an active area of design refinement.
• Expanded indications: Current VBT is primarily used for thoracic curves in skeletally immature patients. Research is evaluating whether lumbar VBT, combined thoracic-lumbar tethering, and application to broader Risser/Sanders stages can be safe and effective.
• Smart tethers: Investigational concepts include tethers with embedded sensors to monitor tension and guide postoperative management, and tension-adjustable cords that allow non-invasive modification of correction forces during growth.
• Registries and outcome tracking: Multiple centers are now contributing to VBT outcome registries (including through the SRS) to build the long-term evidence base that families and surgeons need for informed decision-making.

The evidence base for scoliosis-specific exercises has strengthened significantly with recent and ongoing randomized controlled trials (RCTs):

• NCT06500806 — Long-term supervised Schroth + bracing: Studying the combination of supervised Schroth exercises with bracing in patients aged 10–17, evaluating whether adding structured exercise to bracing improves outcomes beyond bracing alone.
• 2024 RCT (Schroth + bracing vs. bracing alone): Found that supervised Schroth exercises combined with bracing improved both curve severity and quality of life compared with bracing alone in AIS patients aged 10–17.
• 2024 prospective controlled study (PSSE-Schroth as sole treatment): Demonstrated that Schroth exercises as the exclusive treatment reduced the risk of curve progression for curves under 25° during early rapid growth.
• 2025 Bayesian network meta-analysis: Synthesized evidence across multiple RCTs and concluded that Schroth and PSSE significantly improved Cobb angle, trunk rotation, and quality of life compared with controls.

Remaining questions being investigated include the optimal dose and frequency of supervised sessions, the durability of exercise-induced improvements after treatment ends, and cost-effectiveness in different healthcare systems. Ongoing trials registered at ClinicalTrials.gov continue to build this evidence base.

ClinicalTrials.gov is the primary registry for clinical trials in the United States and internationally. To search for scoliosis trials:

• Search for “scoliosis” and filter by recruiting status, age group, and location.
• Look for trials at institutions listed in the Specialty Centers section above — high-volume centers are more likely to offer trial access.
• Ask your spine specialist directly whether any trials are available and appropriate for your situation.
• Understand that clinical trial participation involves risks and benefits that should be discussed thoroughly with the research team.

Key trial identifiers referenced in this guide: NCT04500041 (casting vs. bracing), NCT05001568 (optimized braces), NCT07045337 (hybrid bracing), NCT06500806 (Schroth + bracing), NCT03365804 (3D brace design).

The U.S. Food and Drug Administration (FDA) regulates spinal devices including pedicle screws, growing rods, and vertebral body tethering (VBT) systems. Key regulatory details:

• Posterior spinal fusion (PSF) hardware: Pedicle screw systems for scoliosis have full FDA clearance (510(k)) and are the standard of care for curves requiring surgical correction.
• MAGEC growing rods: FDA-approved magnetically controlled growing rods for early-onset scoliosis, allowing non-invasive lengthening. NuVasive MAGEC received 510(k) clearance; however, in 2020 an FDA safety communication noted reports of pin breakage and metallosis, and the device was temporarily recalled in some markets outside the U.S. Updated design improvements have been implemented.
• Vertebral body tethering (VBT): The Zimmer Biomet Tether received FDA Humanitarian Device Exemption (HDE) approval in 2019 for skeletally immature patients (Sanders 4–6, Risser 0–2) with progressive idiopathic scoliosis (Cobb 30°–65°, thoracic curves). HDE status means the device is approved for conditions affecting fewer than 8,000 patients per year, and its use is monitored under institutional review board (IRB) oversight at implanting hospitals.
• ApiFix MID-C: Received FDA Humanitarian Device Exemption (HDE H170001, 2019) for a posterior dynamic deformity-correction device for moderate, flexible adolescent idiopathic scoliosis (Cobb 30–60°).
• Bracing: Custom thoracolumbosacral orthoses (TLSOs) do not require individual FDA clearance, though the materials and manufacturing processes are FDA-regulated. Bracing remains widely available across all 50 states through certified orthotists.

In the EU, spinal implant devices are regulated under the Medical Device Regulation (MDR 2017/745), which replaced the older Medical Device Directive (MDD) with stricter requirements effective May 2021.

• CE marking: Pedicle screw systems, growing rods, and VBT devices require CE marking for legal sale in EU member states. Most major systems used in the U.S. also carry CE marks and are available across Europe.
• MAGEC growing rods: CE-marked and widely used in Europe. In 2020, the UK’s MHRA issued a Medical Device Alert (MDA/2020/014) after reports of titanium rod fracture and metallosis. NuVasive suspended EU distribution temporarily; updated devices were re-introduced after design modifications.
• VBT availability: VBT is performed at select specialized centers in France, Germany, the Netherlands, and other EU countries. Unlike the U.S. HDE pathway, VBT devices in Europe are used under CE marking with fewer institutional oversight requirements, though major centers maintain their own registries.
• Schroth and PSSE: Scoliosis-specific exercise methods originated in Europe (Schroth in Germany, SEAS in Italy) and are deeply integrated into standard care. SOSORT, headquartered in Europe, publishes the international bracing and exercise guidelines. Many European systems fund structured physiotherapy for scoliosis as part of national health coverage.
• Bracing: European brace designs (Chêneau, Gensingen, SPoRT, Sforzesco) are widely used and have strong published evidence. Some designs are not routinely available in the U.S. but can be accessed through certified European-trained orthotists in select American practices.

• NICE guidance: The National Institute for Health and Care Excellence does not publish a dedicated scoliosis-specific guideline, but surgical and device interventions are evaluated through the Interventional Procedures Programme. NICE issued Interventional Procedure Guidance (IPG) on vertebral body tethering (IPG699, 2021), acknowledging insufficient evidence for routine use and recommending VBT be performed only under research or special governance arrangements with data collection.
• MHRA: The Medicines and Healthcare products Regulatory Agency oversees device safety post-Brexit. As noted above, the MHRA issued safety alerts regarding MAGEC growing rods in 2020.
• NHS access: Posterior spinal fusion for scoliosis is routinely available through the NHS at designated spinal deformity centers. Bracing is available through NHS orthotic services. VBT is generally only available in the UK through private practice or approved research programs.
• Schroth physiotherapy: Scoliosis-specific physiotherapy (including Schroth) is increasingly available in the UK, though NHS provision varies by region. Many patients access specialized physiotherapy through private practitioners.

• PMDA regulation: The Pharmaceuticals and Medical Devices Agency regulates spinal devices in Japan. Pedicle screw systems for scoliosis are approved and widely used at major Japanese spine centers.
• VBT: Not widely available in Japan as of 2026. Japanese scoliosis surgeons have generally followed the PSF approach, though some centers are evaluating fusionless techniques in research settings.
• School screening: Japan maintains one of the most systematic school scoliosis screening programs in the world, with mandatory screening introduced in 1979 (Gakko Hoken-ho). This has led to earlier detection and a strong referral infrastructure. Studies from Japan have demonstrated that screening reduces the rate of surgery by enabling earlier bracing.
• Conservative management: Japanese orthopedic practice has traditionally emphasized bracing and observation with strong adherence to monitoring protocols. Japanese-designed braces (e.g., OMC brace) are used domestically.

• Device regulation: Health Canada regulates spinal devices as Class III or IV medical devices. Pedicle screw systems and growing rods are licensed and available at major pediatric spine centers.
• VBT: Performed at select Canadian centers, including SickKids (Toronto) and BC Children’s Hospital (Vancouver). Device access is through Health Canada licensing. Canadian centers are contributing data to international VBT registries.
• Provincial coverage: Scoliosis surgery (PSF) is covered by provincial health plans at designated centers. Wait times for elective scoliosis surgery vary by province. Bracing is generally covered, though custom brace funding varies by provincial program.
• Schroth physiotherapy: Available in major Canadian cities, though not uniformly funded by provincial health plans. The SOSORT-certified therapist network is growing, particularly in Ontario and British Columbia.

• TGA regulation: The Therapeutic Goods Administration regulates spinal devices under the Australian Register of Therapeutic Goods (ARTG). Standard pedicle screw systems and growing rods are available.
• VBT: Available at select centers, primarily in Sydney and Melbourne. Australian surgeons have been active in publishing VBT outcome data and contributing to international registry efforts.
• Scoliosis screening: Australia does not have a mandatory national school screening program for scoliosis, unlike Japan. Screening is opportunistic through general practitioners and school nurses.
• Medicare coverage: Scoliosis surgery is covered under Medicare and private health insurance. Bracing is partially subsidized through various state-based programs.

While the core principles of scoliosis management are consistent worldwide, there are notable regional differences:

• Bracing threshold: The SRS/SOSORT guideline recommends bracing for progressive curves of 25°–40° in skeletally immature patients. European practice tends to initiate bracing at slightly lower thresholds (some centers begin at 20° with documented progression), while North American practice more commonly waits until 25° with progression.
• Exercise as primary treatment: In Central Europe (Germany, Austria, Poland), scoliosis-specific exercise therapy (Schroth, BSPTS) is considered a standard first-line intervention for mild to moderate curves, often before bracing is considered. In the U.S. and Canada, exercise therapy has traditionally played a supplementary role to bracing, though this is changing as the evidence base grows.
• Surgical thresholds: The general surgical threshold of 45°–50° for AIS is consistent across major international societies. However, the willingness to consider fusionless alternatives (VBT, ApiFix) at earlier curve magnitudes varies by region and individual surgeon experience.
• School screening: Japan and some U.S. states mandate school scoliosis screening. The U.S. Preventive Services Task Force (USPSTF) has concluded that current evidence is insufficient to assess the balance of benefits and harms of screening in asymptomatic adolescents (2018 statement), whereas SRS, AAP, AAOS, and POSNA support screening. This creates regional variability in screening practices within the United States.

Harrington rods were the dominant surgical technique for scoliosis from the 1960s through the 1980s. The system used a single distraction rod on the concave side of the curve to straighten the spine. While revolutionary at the time, Harrington rods had significant limitations: they did not correct rotational deformity, required prolonged postoperative immobilization (often in a cast or brace for 6–12 months), and were associated with a high rate of “flatback syndrome” — loss of normal lumbar lordosis causing chronic pain, forward lean, and disability in adulthood. Modern pedicle screw fixation, introduced in the 1990s, provides three-dimensional correction, eliminates the need for postoperative bracing, and produces far superior long-term outcomes. Harrington rods are no longer used in modern scoliosis surgery, though some adults living with Harrington instrumentation may present for evaluation of flatback syndrome or adjacent segment degeneration.

In the 1970s and 1980s, electrical muscle stimulation (EMS) was investigated as a non-invasive alternative to bracing for adolescent idiopathic scoliosis. The theory was that electrically stimulating the muscles on the convex side of the curve during sleep would correct the curvature over time. Multiple studies, including randomized controlled trials, demonstrated that electrical stimulation was no more effective than observation alone at preventing curve progression. The approach was abandoned by the early 1990s after consistent failure to demonstrate benefit across multiple well-designed studies.

The Milwaukee brace (cervical-thoracic-lumbar-sacral orthosis, or CTLSO) was the first widely used brace for scoliosis, introduced in the 1940s. It extends from the pelvis to the chin with a neck ring, making it highly visible and socially difficult for adolescents to wear. Studies consistently showed poor compliance due to the brace’s conspicuous design and discomfort. Modern underarm TLSO braces (Boston, Rigo-Chêneau, Providence) achieve equivalent or superior curve control for thoracic curves without the neck ring, with significantly better patient compliance and quality of life. The Milwaukee brace is rarely prescribed today and has been largely replaced by underarm designs for all but the highest thoracic curves (apex above T6).

For decades, general exercise (swimming, gymnastics, yoga) was recommended to patients with scoliosis as a treatment to correct or slow curve progression. While general physical activity is beneficial for overall health and well-being, systematic reviews have found no evidence that general exercise (as opposed to scoliosis-specific exercise programs like Schroth or SEAS) prevents curve progression in adolescent idiopathic scoliosis. SOSORT guidelines explicitly distinguish between scoliosis-specific exercises (which have evidence of benefit) and general exercise (which does not modify the natural history of scoliosis). General exercise and sport are encouraged for fitness and quality of life, but should not be substituted for evidence-based treatments when curve management is indicated.

Chiropractic spinal manipulation has been promoted by some practitioners as a treatment for adolescent idiopathic scoliosis. Multiple systematic reviews, including Cochrane-level analyses, have found no evidence that chiropractic adjustments reduce Cobb angle, prevent curve progression, or avoid surgery in structural scoliosis. The SRS and major orthopedic societies do not recommend spinal manipulation as treatment for scoliosis. While chiropractic care may provide symptomatic relief for back pain in some individuals, it should not be used as an alternative to evidence-based scoliosis management (bracing, scoliosis-specific exercises, or surgery) when indicated. Families should be aware that delays in appropriate treatment while pursuing unproven therapies may lead to curve progression past treatable thresholds.

Vertebral body stapling (VBS) uses shape-memory alloy (nitinol) staples placed across growth plates on the convex side of vertebrae to selectively restrict growth. The concept is similar to VBT (growth modulation) but uses rigid staples rather than a flexible tether. Early clinical experience in the 2000s showed variable and often disappointing results: many patients had inadequate curve control and progressed to needing fusion surgery. Studies reported failure rates of 40–50% for thoracic curves. The approach has largely been supplanted by VBT, which provides adjustable compression across more vertebral levels and has demonstrated superior curve correction. Some research groups continue to refine staple design, but first-generation VBS is no longer widely used.

Anterior spinal fusion (ASF) using anterior instrumentation (rods and screws placed from the front of the spine through a thoracotomy or thoracoabdominal approach) was once commonly used for thoracolumbar and lumbar AIS curves. The approach required diaphragm takedown for thoracolumbar curves and was associated with higher rates of pulmonary complications, longer operative times, and greater blood loss compared with posterior-only approaches. As posterior pedicle screw fixation improved and demonstrated equivalent or superior correction of these curve types with lower morbidity, anterior fusion for routine AIS fell out of favor. It is now rarely performed for standard AIS, though anterior releases may still be used in select severe or rigid deformities.
