Abstract

Purpose: To review the clinical and radiological results after an open reduction and internal fixation with a T-shaped LCP for unstable distal clavicle fractures. Materials and Methods: From February 2005 to June 2006, ten patients with distal clavicle Neer type II fractures were treated with an open reduction and internal fixation with a T-shaped LCP. Bony union was identified by plain radiography. The clinical results were analyzed according to the UCLA scoring system. Results: The mean time to fracture union was 9weeks and union was achieved in all cases. The mean UCLA score was 33.4 (30-35); excellent in 8 cases and good in 2 cases. In one case, loosening of one distal screw was occured and mild AC joint subluxation was observed in another case. Conclusion: 3.5 mm T-shaped LCP fixation is a useful technique for treating unstable distal clavicle fractures. This procedure provide stable fixation with no further AC joint injury.

목적: 쇄골 원위부 불안정성 골절에 대하여 3.5 mm T형 잠김 금속판을 이용한 내고정을 시행한 후 임상적 결과를 보고하고자 한다. 대상 및 방법: 2005년 2월부터 2006년6월까지 3.5 mm T형 잠김 금속판을 이용하여 수술적 치료를 시행한 Neer 2형 원위 쇄골 골절 환자 중 1년 이상 추시가 가능하였던 10예를 대상으로 후향적 연구를 시행하였다. 남자가 6예 여자가 4예였으며, 평균 연령은 45.7세($32{\sim}62$)였다. 동반 손상은 다발성 골절이 1예가 있었으며, 비수술적 치료의 실패로 불유합이 발생하여 자가골 이식술을 동반한 수술적 치료를 시행한 예가 2예 있었다. 평균 추시 기간은 14.8개월($12{\sim}22$)이었으며, 골유합은 단순 방사선검사 소견으로 판정하였고, 임상적 결과는 UCLA점수와 관절 운동 범위 등으로 평가 하였다. 결과: 방사선학적 골유합은 평균 9주($6{\sim}12$주)에 얻을 수 있었으며, 최종 추시 시 UCLA 점수는 평균 33.4점($30{\sim}35$)으로 전예에서 양호 이상의 결과를 얻었고, 관절 운동 범위도 전예에서 정상으로 회복되었다. 합병증으로 1예에서 나사못의 이완소견이 관찰 되었고, 1예에서 견봉-쇄골 관절의 경도의 아탈구가 발생하였으나, 결과에 영향을 미치지는 않았다. 결론: 불안정성 원위 쇄골 골절에 사용한 3.5 mm T형 잠김 금속판을 이용한 내고정은 견봉 쇄골 관절에 영향을 주지 않으며, 견고한 고정을 얻을 수 있었고, 분쇄의 정도가 아주 심하지 않은 원위쇄골 골절의 치료 시 고려 할 수 있는 유용한 술기로 사료된다.
