금속 대 금속 고관절 표면 치환술의 최소 4년 추시 결과

국문 초록 (Abstract)

목적: 금속 대 금속 고관절 표면 치환술의 최소 4년 추시 결과를 보고하고자 하였다.
대상 및 방법: 1998년 11월부터 2001년 9월까지 금속 대 금속 고관절 표면 치환술을 시행 받고 최소 4년 이상 추시 관찰이 가능하였던 36명, 39 고관절을 대상으로 하였다. 평균 연령은 45세(28-69세), 평균 추시 기간은 51.9개월(48-82개월)이었다. 임상적 평가를 위해 해리스 고관절 점수 설문 및 술 후 보행 분석을 시행하였다. 방사선학적으로는 술 후 주기적으로 전후면 및 횡측면 방사선 사진을 촬영하였다. 세라믹 대 세라믹 관절면 고관절 전치환술군 21예를 대조군으로 코발트와 크롬의 혈중 농도를 측정하여 비교하였다.
결과: 해리스 고관절 점수는 술 전 평균 61점(31-74점)에서 최종 추시에서 평균 96점(85-99점)으로 향상되었다. 비구컵의 해리는 보이지 않았고 대퇴 부품의 삽입 각도는 대퇴골 간부에 대해 평균 136°로 22 고관절(61.1%)에서 130-140o의 범위에 있었다. 4년 추시상 생존율은 97.4%이었으며, 혈중 코발트, 크롬 농도 모두가 대조군에 비해서 증가된 소견을 보였다(p＜0.05).
결론: 고관절 표면 치환술은 단기 추시 결과 우수한 생존율을 보였으나 향후 더 많은 증례에서의 장기 추시가 필요하며, 금속 이온 유리에 대한 관찰이 필요하다고 생각된다.

Purpose : To report the minimum 4 year follow up results of metal on metal hip resurfacing arthroplasty.
Materials and Methods : 39 hips from 36 patients, who received hip resurfacing from November 1998 to September 2001 and were followed up for at least 4 years, were enrolled in this study. The average age was 45 years (28-69 years) and the average follow up period was 51.9 months (48-82 months). A clinical evaluation was performed with the Harris Hip Score and gait analysis postoperatively. A radiologic evaluation was performed regularly after surgery using anteroposterior and lateral simple radiographs. The post-operative cobalt-chrome serum concentration was measured and compared using 21 cases of ceramic-on-ceramic total hip arthroplasty as a control group.
Results : The Harris Hip Score improved from 61 points (31-74) preoperatively to 96 points (85-99) postoperatively. There were no cases of acetabular loosening, and the average angle of femoral insert to the shaft was 136° with 22 hips (61.1%) being within 130-140o. The 4 year follow-up survival rate was 97.4%. The serum cobalt and chrome levels were higher than the control group (p＜0.05).
Conclusion : Hip resurfacing showed excellent survival rate after a short-term follow-up, but still requires a long-term evaluation with more cases and further metal ion release studies.
