title: Intertrochanteric varus osteotomy in Legg-Calvé-Perthes disease: a report of 112 hips.
abstract: The results of 112 intertrochanteric femoral varus osteotomies performed on 102 children with Legg-Calvé-Perthes disease were analyzed. The result worsened with the increasing age of the patient at operation. It was seldom good when the patients age was greater than or equal to 9 years. Catterall grouping and the concept of head at risk were of prognostic significance in patients operated on before 9 years of age and before the disease had reached the healing phase. No correlation was observed between the result and the femoral neck-shaft angle measured preoperatively and after consolidation of the osteotomy.
