Scheuermann's Disease (Juvenile Kyphosis)
A structural kyphosis developing during adolescent growth — the most common cause of hyperkyphosis in teenagers
ICD-10: M42.00 · thoracic condition
Scheuermann's disease is the most common structural cause of hyperkyphosis (excessive rounding of the upper back) in adolescents and young adults. It occurs when vertebral bodies develop irregular, wedge-shaped deformities during the growth spurt, typically at the thoracic or thoracolumbar spine. Unlike postural kyphosis — which is flexible and corrects when the patient lies flat or extends the spine — Scheuermann's kyphosis is structural and rigid. The condition affects approximately 1–8% of the adolescent population and is more common in males. Scheuermann's disease is diagnosed radiographically when three or more consecutive vertebral bodies are wedged 5 degrees or more, often accompanied by Schmorl's nodes (disc material herniating into the vertebral endplate).
1–8%
Scheuermann's disease affects approximately 1–8% of the adolescent population and is 2–3 times more common in males than females.

Bracing in skeletally immature patients with Scheuermann's kyphosis achieves an average curve reduction of 10–15 degrees with consistent wear.
American Academy of Orthopaedic SurgeonsSymptoms
- Visible rounding of the upper back (thoracic kyphosis) that does not straighten with extension
- Back pain — particularly in the thoracolumbar region during or after the growth spurt
- Tight hamstrings and hip flexors
- Fatigue with prolonged sitting or standing
- Self-consciousness about posture in adolescents
- In severe curves (>70–80 degrees): reduced pulmonary capacity and dyspnea on exertion
Causes & Risk Factors
- Abnormal cartilaginous growth plates in the vertebral endplates during adolescent growth — the precise trigger is unknown
- Possible genetic component — the condition often runs in families
- Repetitive loading during rapid growth (heavy labor, sports) may play a role in predisposed individuals
- Mechanical factors — anterior vertebral body loading during growth
Treatment Options
Conservative
- Physical therapy — extension exercises, core strengthening, and hamstring stretching
- Bracing (Milwaukee or thoracolumbar-sacral orthosis) — most effective for curves 45–65 degrees in skeletally immature patients with growth remaining
- NSAIDs for pain management during active growth phase
- Activity modification — avoiding heavy axial loading activities during bracing
Surgical
- Posterior spinal fusion with instrumentation — for curves exceeding 70–75 degrees, or those causing significant pain or neurological compromise
- Combined anterior-posterior approach — occasionally used for very stiff, large curves
When to see a spine specialist
Consult a spine specialist or pediatric orthopedic surgeon if your child has a noticeable rounding of the upper back that does not correct with postural effort, if back pain is limiting activity, or if the curve is progressing. Early evaluation during the growth years (typically ages 10–16) offers the best window for brace treatment to influence curve progression.

How is Scheuermann's disease different from bad posture?
The key distinction is rigidity. Postural kyphosis — the most common cause of a rounded back in teenagers — corrects completely when the patient lies flat or is asked to extend the spine. Scheuermann's kyphosis is structural and rigid: it does not straighten with position change. Radiographically, Scheuermann's shows wedged vertebral bodies (≥5 degrees at ≥3 consecutive levels) and often Schmorl's nodes, while postural kyphosis shows no vertebral body deformity.
Does Scheuermann's disease get worse over time?
Most curves in Scheuermann's disease stabilize when skeletal maturity is reached (typically at Risser grade 5, around age 16–18). Curves greater than 55–60 degrees at skeletal maturity are at risk for slow progression into adulthood. Adult patients who had uncorrected Scheuermann's kyphosis greater than 70 degrees may experience increasing back pain and, in severe cases, cardiopulmonary compromise from chest restriction.
Is bracing effective for Scheuermann's disease?
Bracing is most effective in skeletally immature patients (Risser 0–2) with curves between 45–65 degrees who wear the brace 16–23 hours per day consistently. Studies show bracing can reduce the curve by 10–15 degrees in compliant patients. Bracing does not work once skeletal maturity is reached, and curves over 70 degrees are unlikely to respond adequately — these patients may be surgical candidates.
