Abstract
In order to determine the role of the spinal muscles in the etiology of the scoliosis associated with Duchenne muscular dystrophy, we carried out a study of 16 children using computerized tomography. Scans were taken at the level of the 9th dorsal and the 3rd lumbar vertebrae. Density readings were taken in the medial and lateral portions of the erector spinae. The results confirmed the loss of muscle and replacement by fat which was greater on the concave side. The density differences between the convex and concave sides correlated with the degree of curvature measured by Cobb's method. Computed tomography may offer a prognostic indicator in the development of scoliosis.
