title: Pemberton osteotomy for the treatment of developmental dysplasia of the hip in older children.
abstract: A retrospective analysis was done of the results of the Pemberton osteotomy for the treatment of developmental dysplasia of the hip in 16 hips of 14 children older than 7 years. The average age of the patients at the time of surgery was 11+6 years and the average follow-up was 4+10 years. Eleven hips required one or more surgical procedures concomitant with the Pemberton osteotomy to achieve a concentric and congruous reduction of the hip joint. None of the hips developed avascular necrosis of the acetabular fragment. The center-edge angle improved from a preoperative average of 1 degree to an average of 30 degrees at the most recent follow-up. Correction of acetabular dysplasia was noted in 14 of the 16 hips, as demonstrated by the improvement in the acetabular index, the center-edge angle, and the Severin class. We believe that the Pemberton osteotomy can be a safe and effective procedure for the treatment of developmental dysplasia of the hip in the older child.
