[Surgery of the lower limbs in Duchenne's muscular dystrophy].

Seventy-one children had surgical procedures on hips and/or knees and/or feet contractures before or after the age of loosing gait. Gait has been continued on 1 year and 7 months to 3 years and 8 months according to the evolving type of Duchenne Muscular Dystrophy (DMD). After analysis of results of the surgery upon contractures, surgical procedures have been determined for each joint. Before loosing gait, but when contractures were all present, surgery prolonged on gait without orthosis and relieved of physiotherapy. During the 6 months after loosing gait, surgery allowed to recover same walking ability more often with orthesis. After loosing gait, surgery gave a better comfort of life to the child and his family.
