Long-term outcome of Legg-Perthes disease after Salter innominate osteotomy / 中国矫形外科杂志

ABSTRACT

[Objective]To observe radiographic morphology of femoral head at skeletal maturity of the Salter innominate osteotomy for treatment of patients with Legg-Perthes disease and evaluate sphericity of the femoral head and congruity of the hip.Based on system review of literatures,thes attempted to determine the indications and methods of treatment.[Method]Sixteen patients of Legg-Perthes disease were treated by Salter innominate osteotomy before 1994.The mean age of patients was six years and seven months at operation.Of them,only were 12 patients followed up 10 years and ten months avergely and mean ages of patients were 17 years and 2 months at last follow-up.Growth of plate of femoral head and Y cartilage of acetabulum was closed,indicating skeletal maturity.[Result]According to Stulberg classification of outcome,there were four cases in Stulberg class Ⅰ and six patient in class Ⅱ and one patient in class Ⅲ and one patients in class Ⅳ and no case in class Ⅴ.Lower limb of shortening was averagely 1.5 cm(ranged 0.8~2.0 cm)and the range of motion of hips was almost normal and no abnormal gait was observed.[Conclusion]The Salter innominate osteotomy could keep sphericity of the femoral head and congruity with acetabulum of the hip for children with Legg-Perthes disease and also could be in aid of preventing premature arthritis of hip.
