목적: 골 관절염을 동반한 이형성 고관절에 시행한 변형된 Chiari 절골술의 결과를 알고자 하였다.
대상 및 방법: 원형(dome)의 절골술로 변형된 Chiari 절골술을 시행받은 이형성 고관절 환자 17명을 대상으로 하였으며, 평균 연령은 33.5세, 평균 추시기간은 28.2개월이었다. 임상적 평가는 절뚝거림, 고관절 운동범위와 Harris Hip Score (HHS)를 사용하였고 방사선학적 평가는 acetabular 각, Center edge 각, 비구피복, 체중부하 관절 간격, 최소 관절 간격 등을 평가하였다.
결과: 수술 전 동통 보행을 호소하던 13예 중 6예에서 호전되었고, 고관절 운동범위도 외전, 외회전, 내회전에서 의의 있게 향상 되었다. HHS 점수는 54.6점에서 81.6점으로 통계학적으로 의의를 보였다. 방사선학적 결과상 acetabular 각, Center edge 각, 비구피복은 각각 수술 전 47.5°, 9.9°, 57.9%에서 최종 추시상 40.0°, 38.5°, 82.4%로 의의있는 변화를 보였다.
결론: 변형된 Chiari 절골술은 조기 및 중기 골 관절염을 동반한 이형성 고관절의 치료에 있어서 임상적, 방사선학적으로 의의있는 효과를 보이는 적절한 방법 중의 하나이다.

Purpose : To evaluate the clinical, radiographic results of a modified Chiari osteotomy for dysplastic hips associated with early osteoarthritis. Materials and Methods : 17 dysplastic hip patients were examined, and treated with modified Chiari osteotomy, which is dome-shaped pelvic osteotomy. Their mean age at surgery was 33.5 years old (range: 14-53 years), and the mean follow-up period was 28.2 months (range: 12-73 months). In the clinical evaluation, limping, range of motion and Harris Hip Score (HHS) were used and in the radiographic evaluation, center edge angle, acetabular angle, head coverage, weight bearing joint space and minimal joint space were evaluated. Results : Six out of 13 patients who had an antalgic gait improved, and the level of abduction, internal rotation and external rotation showed significant improvement at the final follow-up. The radiographic results showed that the acetabular angle improved significantly from 47.5° preoperatively to 40.0° at the last follow-up. The center edge angle showed significant improvement from 9.9° preoperatively to 38.5° at the last follow-up and the head coverage also showed significant improvement from 57.9% preoperatively to 82.4% at the last follow-up. Conclusion : A modified Chiari osteotomy is an effective method for a dysplastic hip with a mild and moderate grade of osteoarthritis, and shows improved clinical and radiographic results.
