• ABSTRACT
    • Six patients with Down syndrome were treated for dislocation of the hip (10 hips). Follow-up averaged 49 months. Group I consisted of three patients (six hips) with dislocatable hips and normal acetabula treated with capsular plication and/or proximal femoral osteotomy. Group II consisted of three patients (four hips) with dislocatable hips and dysplastic and insufficient acetabula treated with capsular plication, Salter osteotomy, and proximal femoral osteotomy. Results were rated as satisfactory in four patients (seven hips) and unsatisfactory in two patients (three hips).
