Spinal deformity is common in muscular dystrophy and usually occurs after loss of walking ability. Unlike in idiopathic and other scoliosis forms, there seems to be no side preference of the convexity. Aim of the study was to analyse, if there is any relation between incidence and extent of walking ability, lower limb contractures and development of scoliosis. In a retrospective study, 45 patients with Duchenne muscular dystrophy who underwent surgery were analysed, concerning walking ability, contractures of lower extremities and scoliosis. 1: No scoliosis was observed in ambulatory patients. 2: 96% of the wheelchair bound patients suffered from scoliosis. 3: 96% of the scoliosis patients had hip flexion or abduction contractures. 4: In 12 of 15 cases with side-different contractures, scoliosis tended to the side with the greater contracture. The influence of hip contracture and pelvic obliquity on scoliosis is discussed controversially. Concerning muscular dystrophy, there seems to be a positive correlation between convexity and hip contracture. If this is a causal relation or if there is a faster progression of structural alteration of the muscles on one side has to be further investigated.
