Abstract

Purpose: The aim of this study is to evaluate the clinical result of intra-articular fractures of the distal humerus (AO type C) in elderly osteoporotic patients treated with double tension band osteosynthesis. Materials and Methods: From January 2006 to December 2010, 10 elderly osteoporotic patients(1 male, 9 females) with intra-articular fractures of the distal humerus (AO type C) were treated with double tension band osteosynthesis. The mean age of patients at the time of surgery was 74.6(66~84) years and the mean follow-up period was 39.2(20~74) months. The fracture union and complications were assessed and the functional result was evaluated by the rating system of Jupiter et al. and the Mayo elbow performance index. Results: Bone union was achieved in all patients with no secondary displacement. The mean time for union was 16.6(13~22) weeks. The average postoperative arc of elbow flexion was 119(100~140) degrees with a mean flexion contracture of 8.5(0~15) degrees. The recovery in two patients was rated as excellent, in 7 as good, and in 1 as fair in terms of the Mayo elbow performance index with average value of 82(70~90) points. Seven patients were rated as excellent, 1 as good, and 2 as fair in terms of the rating system of Jupiter et al. Changing tension band wiring was performed in one patient as skin irritation was noticed due to tension band knots. Heterotopic ossification developed in one patient but had no symptom. Conclusion: Double tension band osteosynthesis in intra-articular fractures of distal humerus (AO type C) in elderly osteoporotic patients can provide sufficient and secure stability to allow early rehabilitation.

목적: 고령 환자의 상완골 원위부 골절에서 이중 강선 장력대 고정술을 이용한 수술의 임상적 결과를 분석하여 그 유용성을 알아보고자 한다. 대상 및 방법: 상완골 원위부 골절 환자 중 AO 분류상 C형 골절과 골다공증을 가진 65세 이상의 고령 환자에서 이중 강선 장력대 고정술을 이용해 관혈적 정복과 내고정을 시행 받은 10예를 대상으로 하였다. 남자가 1명, 여자가 9명이었으며 평균 연령은 74.6(66~84)세였다. 평균 추시 기간은 39.2(20~74)개월이었다. 골유합 유무, 시기와 주관절의 운동 범위를 측정하였고, Mayo 주관절 수행 점수, Jupiter 등에 의한 평가법을 이용하여 기능 상태를 평가하였다. 결과: 골유합은 10명에서 2차적인 전위 없이 이루어졌고, 평균 골유합 기간은 16.6(13~22)주였다. 최종 추시시 측정한 평균 주관절 운동범위는 굴곡 구축은 8.5 (0~15)도, 후속 굴곡 119(100~140)도, Mayo 주관절 수행 점수는 82(70~90)점으로 각각 우수 2예(20%), 양호 7예(70%), 보통 1예(10%)였다. Jupiter 등에 의한 평가법을 따르면 각각 우수 7예(70%), 양호 1예(10%), 보통 2예(20%)였다. 1예에서 이소성 골화가 있었으나 그에 따른 증상은 동반되지 않아 추시 관찰하기로 하였으며, 1예에서 강선에 대한 피부 자극 증상이 발생하여 장력대 강선 교체 수술을 시행하였다. 결론: 골다공증을 가진 고령 환자의 상완골 원위부 C형 골절의 수술적 치료에서 이중 강선 장력대 고정술은 견고한 고정과 동시에 조기 관절 운동을 가능하게 하여 효과적이며 우수한 치료법으로 사료된다.
