scheuermann's disease is a condition in which some of the bones of the spine (vertebrae) develop wedge-shaped deformities. this causes curvature of the spine (rounding of the back, or kyphosis), most commonly in the upper back.
most of the time, curvature of the spine can get better with treatment. bracing often prevents further progression of the disease and may improve the existing curvature. exercises and good posture can also be helpful. surgery is occasionally needed.
scheuermann's disease occurs most often in growing teens. the cause is unknown. it is usually not serious, but treatment may be needed if the problem is severe.
