Abstract

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 degrees to 26.4degrees. The mean center-edge angle increased from 14.2degreesto 41degrees. 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.
