Objectives: The goals of surgery are to reorient the biomechanical relationships such that the development of degenerative hip disease is delayed or prevented. To achive these goals, various pelvic osteotomies have been used. We preferred the Steel Triple Innominate Osteotomy to treat acetabular dysplasia.
Materials and Methods: During the period between November 2003 and March 2007, triple innominate osteotomy was performed on 30 patients and 31 hips. There were 27 women and 3 men. The average clinical follow-up was 24.1 months (range 12-52 months). The average age at surgery was 31.1 years (range 16-52 years).
Results: Preoperative hip score increased from an average 64.3° preoperative to 82.9° postoperative. The CE angle was increased from an average 5.42° preoperative to an average 24.52° postoperative. The VCE angle was increased from an average 8.94° preoperative to an average 29.1° postoperative. The Sharp angle was decreased from an average 50.71° preoperative to an average 37.68° postoperative. The Tönnis angle was decreased from an average 22.32° preoperative to an average 11.52° postoperative. The percentage of the femoral head covered by the acetabulum increased from 59.23% to 79.77%. These parameters were significant statistically (p
