Abstract

Purpose: The purpose of this study was to evaluate the radiologic and clinical outcomes after intercalary tricortical iliac bone graft with plate fixation for the nonunion of midshaft clavicular fractures. Material and Methods: Between September 2007 and May 2011, 10 patients who were treated by the intercalary tricortical iliac bone graft, with plate fixation for clavicle nonunion, were studied. The mean follow-up period was 30.7 (12~57) months. After the sclerotic bone was excised to the bleeding cortical bone, we interposed the tricortical iliac bone to provide structural support and restore clavicle length, and then fixed the plate and screws. The radiologic outcomes on the serial plain radiographs and clinical outcomes, according to UCLA, ASES and Quick DASH scores, were analyzed. Results: Bony union was obtained in all cases (100%) and the average union time was 18.4 (14~24) weeks. The average respective UCLA and ASES scores improved from 16.7 and 52.1 preoperatively to 27.4 and 83.6 postoperatively (p<0.05). The average Quick DASH score was 40.5, at the final follow-up. Complications were 2 shoulder stiffness, and one case had removal of device and arthroscopic surgery at 11 months, postoperatively. There were no implant failure or infection. Conclusion: Intercalary tricortical iliac bone graft, with plate fixation for the nonunion of midshaft clavicular fractures, is a good option that can provide structural support and restore clavicle length, as well as high union rate.

목적: 쇄골 간부 불유합에서 개재 삼면피질 장골 이식술 및 금속판 고정술을 시행하고 그 방사선학적 및 임상적 결과를 알아보고자 하였다. 대상 및 방법: 2007년 9월부터 2011년 5월까지 쇄골 간부 불유합으로 개재 삼면피질 장골 이식술 및 금속판 고정술을 시행한 10예를 대상으로 하였으며, 평균 추시 기간은 30.7 (12~57)개월이었다. 불유합 부위의 경화된 골을 충분히 절제한 후 구조적 지지 및 쇄골 길이를 회복할 수 있도록 삼면피질 장골을 골 결손 부위에 개재한 후 금속판 고정술을 시행하였다. 술 후 방사선적 평가는 단순 방사선 사진을 이용하여 골 유합을 판단하였고, 임상적 평가는 UCLA, ASES, Quick DASH 평가 점수를 이용하였다. 결과: 전 예에서 골 유합을 얻을 수 있었으며, 평균 골 유합 기간은 18.4 (14~24)주였다. UCLA 점수는 술 전 평균 16.7점에서 최종 추시 시 평균 27.4점으로, ASES 점수는 술 전 평균 52.1점에서 최종 추시 시 평균 83.6점으로 호전되었다 (p<0.05). 최종 추시 시 Quick DASH 점수는 평균 40.5점이었다. 합병증으로 2예에서 견관절 강직이 있었으며, 그 중 1예는 술 후 11개월째 금속물 제거술과 함께 견관절 관절경 수술을 시행하였다. 그 외 고정물의 파손 및 감염 등의 합병증은 없었다. 결론: 쇄골 간부 불유합에서 개재 삼면피질 장골 이식술은 구조적 지지대 역할 뿐만 아니라 쇄골의 길이를 회복할 수 있는 좋은 술식으로 사료된다.
