Abstract

Summary

This study reviewed at skeletal maturity 180 congenitally dislocated, subluxed, and dysplastic hips in 122 patients treated by the same surgeon by using Salter's innominate osteotomy (IO). The mean follow-up was 12 years. The sex of the patient, the laterality and height of the dislocation, the pre-operative acetabular angle, the amount of femoral antetorsion, or the development of postoperative complications (except avascular necrosis of the femoral head), or a combination of these were not found to have a significant influence on the result. However, those patients who had a previous unsuccessful treatment of the hip, who developed pre- or postoperative avascular necrosis, who were unable to be restored by the osteotomy to a normal acetabular angle, or who required an open reduction of the hip joint(or who had a combination of these) were more likely to have an abnormal result. An important finding was that patients who underwent IO before age 4 years were the most likely candidates to receive a very satisfactory result.
