고관절 이형성증에서 시행한 비구주위 회전 절골술 = 단기 추시 결과

국문 초록 (Abstract)

목적: 고관절의 비구 이형성증 환자에서 시행한 비구주위 회전 절골술의 임상적, 방사선학적 단기 추시 결과를 보고하고자 한다.
대상 및 방법: 비구주위 회전 절골술을 시행 후 1년 이상 추시 된 34명 36예를 대상으로 고관절 운동법위, Harris 고관절 점수, CE 각(center edge angle), Sharp 각, A-H지표(acetabular head index), Tonnis 등급을 이용하여 평가 하였다.
결과: 고관절 운동범위는 수술 전ㆍ후 차이가 없었으며, Hams 고관절 점수는 수술 전 79.4점(60-89점)에서 수술 후 95.1 (82-100점)으로, CE 각이 수술 전 7.1° (-7~19°)에서 수술 후 33.8°(27-44°)로, Sharp 각은 수술 전 43.5° (26-53°)에서 수술 후 39.7° (30-49°)로, A-H 지표는 수술 전 56% (34-72%)에서 수술 후 90% (73-99%)로 향상되었다. 최종 추시시 Tonnis 등급은 무변 25예, 호전 9예, 진행 2예였다. 1예는 인공 고관절 전치환술이 시행되었다.
결론: 비구주위 회전 절골술은 고관절 이형성증의 치료 및 이차적 고관절염 예방에 권장할 만한 치료법으로 여겨지나 숙달된 수술 수기가 요구된다.

Purpose: To evaluate the short term results of a periacetabular rotational osteotomy in early and moderate osteoarthritis of hip dysplasia by comparing the clinical findings and radiological measurements.
Materials and Methods: Thirty-six cases (34 patients) who received periacetabular rotational osteotomy for hip dysplasia with pain and could be followed up for more than one year were reviewed. The clinical findings were evaluated by the range of motion and HHS. The radiological measurements were evaluated using the center edge angle (CE angle), Sharp angle, acetabular-head index (A-H index) and Tonnis grade.
Results: The average Harris hip score improved from 79.4 points (60 to 89 points) to 95.1 points (82 to 100 points). The average range of motion did not change significantly. The mean CE angle increased from 7.1° (-7° to 19°) to 33.8° (27° to 44°), the mean sharp angle increased from 43.5° (26° to 53°) to 39.7° (30° to 49°), the mean A-H index increased from 56% (34% to 72%) to 90% (73% to 99%). The Tonnls grade had remained unchanged in 25 cases, improved in 9, and worsened in two. One case underwent total hip arthroplasty.
Conclusion: The periacetabular rotational osteotomy is the preferred method for treating hip dyaplasia and preventing secondary osteoarthritis. However, a skillful technique is mandatory.
