As you know, Scheuermann's disease is a forward curvature or kyphosis of the upper back area. Males and females are affected equally. Less than 10 per cent of the population is affected by this condition. The exact cause is unknown.
Studies show a higher rate of disabling back pain in adults with untreated Scheuermann's disease. Untreated patients with this condition are more likely to be limited in their job choices. They tend to have sedentary jobs or occupations. They are also more likely to remain single and never marry.
Surgery is advised when the curve is more than 75 degrees as measured on X-rays. Pain, neurologic problems, and cardiopulmonary impairment are other reasons to consider surgery. Bone graft is used along with rods and screws to fuse the spine usually from T2 to L2. Bracing is required after surgery but the result is often a near normal spinal curve and appearance.
