Abstract

Purpose: We compared the results of arthroscopic Bankart repair using metal and biodegradable anchor fixation. Materials & Methods: We reviewed 26 patients with anterior shoulder instability treated by arthroscopic Bankart repair from October, 2006, to March, 2007, 15 patients with metal anchors and 11 patients with biodegradable anchors. The average age was 27.4 years old (range: 17~55) and mean follow-up was 14 months (range: 12~17 months). Functional outcome was evaluated using the Korean Shoulder Score for Instability (KSSI), Rowe's Bankart Grading scale (RBGS), ASES score, and UCLA scores. Results: In the metal-anchor group, the improvements of mean KSSI, ASES, UCLA score, and RBGS were 20.6, 24.0, 4.0, and 45.5, respectively. In the biodegradable anchor group, improvements of mean KSSI, ASES, UCLA score, and RBGS were 21.0, 23.6, 4.6, and 48.9. The improvements in final outcomes were not significantly different (p>.05). One metal problem and one traumatic redislocation occurred in the metal group. Conclusion: Both techniques produced satisfactory outcomes in the treatment of traumatic anterior instability. The biodegradable anchor group could also avoid problems with metal anchors.

목적: 본 연구의 목적은 관절경하 Bankart 수복술에서 금속 봉합나사못과 생체흡수성 봉합나사못을 사용 시의 결과를 비교하는데 있다. 대상 및 방법: 2006년 10월에서 2007년 3월까지 견관절 전방 불안정에 대해 관절경하 Bankart 수복술을 시행한 26명을 대상으로 하였고, 금속 봉합나사못 군(GI)은 15명, 생체흡수성 봉합나사못 군(GII)은 11명이었다. 조사대상의 평균연령은 27.4세였고, 평균 추시기간은 14개월이었다. 기능평가는 KSSI 점수, Rowe 점수, ASES점수, UCLA 점수를 사용하여 평가하였다. 결과: 금속 봉합나사못 군(GI)에서 KSSI, ASES점수, UCLA점수, Rowe 점수들의 평균값의 상승은 각각 20.6, 24.0, 4.0, 45.5이었고, GII에서는 각각 21.0, 23.6, 4.6, 48.9였다. 최종 추시 시 두 군에서 기능평가상 유의한 차이를 보이지 않았지만(p>.05), GII에서 금속돌출로 인한 문제와 외상에 의한 재탈구가 각각 1예씩 있었다. 결론: 두 군 모두 만족스런 결과를 보였으며, 생체흡수성 봉합나사못을 사용할 경우 금속으로 인한 문제를 피할 수 있는 이점이 있어 추천할 만한 술식으로 생각되었다.
