Scheuermann disease

[Sommer]

Scheuermann disease is an osteochondrosis that causes localized changes in vertebral bodies, leading to backache and kyphosis. Diagnosis is with spinal x-rays. Treatment usually involves only reduction of weight bearing and strenuous activity.
Scheuermann disease manifests in adolescence and is slightly more common among boys. It probably represents a group of diseases with similar symptoms, but etiology and pathogenesis are uncertain. It may result from osteochondritis of the upper and lower cartilaginous vertebral end plates or trauma. Some cases are familial.
Most patients present with a round-shouldered posture and they may have persistent low-grade backache. Some have an appearance similar to people with Marfan syndrome; trunk and limb length are disproportionate. Normal thoracic kyphosis is increased diffusely or locally.
