[Salter innominate osteotomy for the treatment of congenital dislocation of the hip].

Thirty-one children (43 hips) were reviewed after having sustained a Salter innominate osteotomy. The average follow up was 10 years. The indication for the osteotomy was a persisting dysplasia after conservative treatment of congenital dislocation of the hip. The X rays study allowed to describe the importance of the remodeling of the femoral head. The overall results were satisfactory in 60 per cent of the cases. The age of the patient at the time of surgery was important: the results being much better in children under 5 years of age. The failures were mostly related to technical faults. However some failures could not be predicted.
