title: Triple osteotomy of the innominate bone for the treatment of congenital hip dysplasia.
abstract: Triple osteotomy of the innominate bone was performed on 12 hips to correct significant, symptomatic hip dysplasia. The procedure used was a modification of Steel's operation, with the modification being removal of a segment of the ischial ramus to facilitate medial displacement and the addition of an acetabular shelf. The patients' ages at surgery ranged from 9 to 22 years, with follow-up of 3-10 years. All patients had clinical improvement in both pain and limp. Radiographically, the average center edge angle improved from 5 to 36.6 degrees. The shelf that was added to buttress further the acetabulum contributed approximately 10 degrees to this improvement in the center edge angle.
