Treatment of supra-condylar fractures of the humerus with a unilateral external fixator

目的 探讨使用外固定架治疗肱骨髁上合并蝶形块的骨折的疗效.方法 2003年6月至2006年10月采用Orthofix外固定架系统治疗AO分型为12-B1.2型的闭合性肱骨髁上骨折28例,按Tscherne and Lobenhoffer分型:Ⅰ型21例,Ⅱ型7例.桡神经损伤2例,均为不完全损伤.结果 28例患者均获得随访,时间12～54个月(平均28个月).骨折全部愈合,时间3～6个月(平均4.5个月).5例患者术后有针道感染伴有针松动.2例桡神经损伤完全恢复,恢复时间2～5个月(平均3.5个月).肘关节功能采用Morrey and Bryan评分:80～100分(平均97分),肩关节功能采用Constant and Murley评分:85～100分(平均98分).结论 单边外固定架是治疗肱骨髁上骨折(AO分型为12-B1.2型)的一种较好的治疗方法,固定有效可靠,允许早期功能锻炼,疗效确切.Objective To evaluate the treatment of supra-condylar fractures of the humerus (12-B1.2 by AO classification) with a unilateral external fixator. Methods From 2003 to 2006,28 cases of supra-condylar fractures of the humerus were treated with a unilateral external fixator. They were 15 males and 13 females. Their average age was 43 (24 to 58) years old. They were all closed fractures and 2 cases complicated with radial nerve injury. Results All were followed up for an average of 28 (12 to 54) months. All fractures united with an average healing time of 4.5 months. The 2 cases of radial nerve injury recovered completely. Five cases had infection of pin holes. The patients had an average elbow score (Money and Bryan system) of 97 and an average shoulder score (Constant and Murley system) of 98. Conclusion The unilateral external fixator is appropriate for supra-condylar fractures of the humerus ( 12-B1.2 by AO classification),because it provides not only effective fixation but also early functional rehabilitation.中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)08710-7131
