Intertrochanteric Varus Osteotomy in Legg-Calvé-Perthes Disease: A Report on 112 Hips

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 patientʼs age was >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.
