목적: 무시멘트 인공관절 치환술을 AML인공 삽입물을 이용하여 수술하고 7년 이상 장기 추시가 가능하였던 환자를 대상으로 다른 문헌상의 결과와 비교하고자 하였다. 대상 및 방법: 1995년 1월부터 2002년 7월까지 본원 정형외과에서 AML 인공관절 기기를 이용 하여 고관절 전치환술을 시행한 환자 중 최소 7년 이상(최저 7.1년, 최고 14.6년, 평균 10.7년) 임상 및 방사선학적 추시가 가능하였던 51명 57예를 대상으로 하여 임상 및 방사선학적 결과에 대해 분석하였다. 결과: 임상 평가는 수술전 평균 Harris 고관절 점수는 52.4점 이었으며, 술 후 평균 Harris 고관절 점수는 최종 추시에서는 88.2점으로 향상되었다. 술 후 대퇴 주대의 초기 고정도 평가상 압박고정 이 된 경우가 40예(70%)였으며 압박고정이 되지 않은 경우가 17예(30%)였다. 최종 압박고정된 40예 중 대퇴 주대의 최종 안정도 평가상 골내성장 고정이 29예(72.5%), 압박 고정이 되지 않은 17예 중 골내성장 고정이 7예(41.2%), 불안정성 고정이 6예(35.3%)였다. 최종 추시 방사선 사진 상 골내성장이 이루어진 36예 중 28예(77.8%)에서 응력 차단을 확인 할 수 있었으며 대퇴골 주위 의 골용해는 21예(36.8%)에서 관찰되었고 비구컵 주위 골용해는 6예(10.5%)에서 관찰되었다. 결론: AML 인공물을 이용한 무시멘트 고관절 전치환술을 시행하고 최소 7년 이상의 추시 관찰을 시행한 결과 우수한 결과를 나타내었으나 폴리에틸렌 마모와 골용해에 대해서는 지속적으로 추시 관찰이 필요할 것으로 사료된다.
Abstract
Purpose: To evaluate the long-term results (minimum 7 Years’follow-up) of cementless total hip arthroplasty using an Anatomic Locking Medullary (AML) hip prosthesis. Materials and Methods: Fifty-one patients (57 hips) underwent total hip arthroplasty between January 1995 and July 2002. They were followed up for a minimum of seven years (7.1 to 14.6) after the initial operation. The mean age of the patients was 56.8 years. The radiographs were reviewed and the clinical results were evaluated. Results: The mean Harris hip score improved from 52.4 points preoperatively to 88.2 points postoperatively. Of the 40 hips showing a good press-fit, 29 hips (72.5%) exhibited bone ingrowth fixation. Of the remaining 17 hips with a poorer press-fit, 7 hips (35.3%) showed bone ingrowth fixation and 6 hips (35.3%) had unstable fixation. Of the 36 hips showing bone ingrowth fixation, 28 hips (77.8%) exhibited stress mediated bone resorption. On the last follow-up radiographic examination, osteolysis occurred around the femoral stem and acetabular cup in 21 (36.8%) and 6 (10.5%) hips, respectively. Conclusion: The results of cementless AML total hip arthroplasty were acceptable up to 7 years but polyethylene wear and osteolysis should be followed carefully over the long term.
