Purpose: To evaluate the clinical and radiologic results of periacetabular osteotomy for the treatment of hip dysplasia.
Materials and Methods : We performed a clinical and radiological assessment of 20 periacetabular osteotomies (19 patients), which had been followed up for>1 year. The mean age of the patients at the time of surgery was 34.2 years (range, 18~50 years). The average follow-up period was 26.7 months (range, 12~85 months). The Harris hip score and range of motion were used for clinical evaluation. The radiologic measurements were evaluated using the acetabular angle, center-edge angle, acetabular depth, femoral head coverage, and medialization.
Results: The mean Harris hip score improved from 59.6 points to 96.4 points. The mean acetabular angle improved from 47.9° to 26.4°. The mean center-edge angle increased from 14.2° to 41°. The acetabular depth increased from 176 to 242.7 The mean femoral head coverage increased from 63.3% to 95.4%. The following complications were noted: hematoma in 2 cases, temporary lateral femoral cutaneous nerve palsy in 3 cases, and superficial wound infection in 1 case.
Conclusion: Periacetabular osteotomy is an effective surgical treatment for hip dysplasia.
