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 $47.9^{\circ}$to $26.4^{\circ}$. The mean center-edge angle increased from $14.2^{\circ}$to $41^{\circ}$. 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.

목적: 비구 이형성증 환자에서 시행한 비구주위 절골술의 임상적 및 방사선학적 결과를 보고하고자 한다. 대상 및 방법: 비구주위 절골술을 시행 받고 1년 이상 추시 가능하였던 19명 20고관절을 대상으로 수술 전후의 임상 및 방사선학적 소견을 비교 분석하였다. 수술 당시 환자의 평균 연령은 34.2세(18~50세)이었으며, 술 후 평균 추시 기간은 26.7개월(12~85개월)이었다. 임상적 평가는 arris 고관절 점수를 이용하였으며, 방사선적 평가로는 비구각, CE 각, 비구 깊이, 대퇴골두 피복 정도, 대퇴골두의 내측 전이의 변화를 비교하였다. 결과: Harris 고관절 점수는 술 전 59.6점에서 최종 추시시 96.4점으로 향상되었다. 비구 각은 술전$47.9^{\circ}$에서 $26.4^{\circ}$로, CE 각은 $14.2^{\circ}$에서 $41^{\circ}$로, 비구 깊이는 176에서 242.7로, 대퇴골두 피복은 63.3%에서 95.4%로 호전을 보였다. 합병증으로는 혈종 발생 2예, 일시적 대퇴부 이상 감각 3예, 표재성 감염 1예가 있었다. 결론: 비구 이형성증 환자에서 비구주위 절골술은 임상 및 방사선학적 호전을 보이는 효과적인 술 방법이다.
