title: Innominate osteotomy for the treatment of Legg-Calvé-Perthes disease.
abstract: A retrospective study was performed in 37 patients who underwent innominate osteotomy for the treatment of Legg-Calvé-Perthes disease. The majority of the patients (81%) were more than 6 years old, and the mean age was 7 years and 6 months. Thirty five hips were Catterall group III or IV, and 2 hips that had clinical and radiological "head at risk" signs were group II. The time interval between surgery and the final follow-up ranged from 2 to 6 years with a mean of 3 years and 10 months. Twenty five of 37 patients had good clinical results, and radiographs showed that the sphericity of the femoral head in the older age (> 8 years) group was poorer, which demonstrated a similar pattern to the clinical results in this age group. We conclude that innominate osteotomy is a safe and effective procedure in severe Legg-Calvé-Perthes disease and this operation should be carefully selected as a treatment method in the appropriate age group.
