title: [Hip joint problems in patients with Down's syndrome].
abstract: 10 patients with Down's syndrome and hip disorders have been examined. Hip instability was present in 5 patients: habitual dislocations occurred in 2 patients, persistent subluxation was found in 2 patients and 1 patient had bilateral fixed hip dislocation. Hip instability usually occurs after the begin of walking and we suggest to perform regularly radiographic examinations on hip instability. Other hip disorders as slipped femoral capital epiphysis may be complicated by hip instability. Legg-Calvé-Perthes disease was found in 2 patients and slipped femoral capital epiphysis in 3 patients. 7 of the 10 patients underwent operative treatment. Subsequently a second or third operation was necessary in 2 patients because of an unexpected instability of the hip following the primary surgery. This was caused by the ligamentous laxity which is often found in Down's syndrome. An increased rate of infections is known in trisomy 21 and wound infections occurred in 2 of the 7 operated patients. Therefore we recommend to consider ligamentous laxity and susceptibility to infection in the treatment of hip disorders in Down's syndrome.
