双切口克氏针及外侧可吸收张力带内固定治疗儿童肱骨髁上骨折

目的：探讨双侧克氏针结合外侧可吸收张力带内固定治疗儿童肱骨髁上骨折的临床疗效。方法：2006年至2010年采用双侧切口切开,交叉克氏针并可吸收张力带内固定治疗82例儿童肱骨髁上骨折,男53例,女29例;年龄5～12岁,平均7岁。根据骨折临床愈合后肘关节屈伸功能及肘部提携角结果,按Flynn评定标准综合评定疗效。结果：82例均获随访,时间0.5年,肘关节屈伸活动受限（2.8±3.7）°,提携角（12.7±2.2）°。依据疗效评定标准,优80例,良2例。结论：采用双侧切口交叉克氏针并可吸收张力带内固定治疗儿童肱骨髁上骨折,能早期进行肘关节功能锻炼,具有创伤小、固定牢固、恢复快的特点,是目前手术治疗儿童肱骨髁上骨折较理想的方法。

Treatment of humeral supracondylar fracture in children with internal fixation using Kirschner wires and biodegradable tension band through double small incisions

Objective: To study therapeutic effects of internal fixation with Kirschner wires and biodegradable tension band through double small incisions for the treatment of humeral supracondylar fracture in children. Methods: From 2006 to 2010,82 children with humeral supracondylar fractures were treated with internal fixation using crossed Kirschner wires combined with biodegradable tension bands. Among the patients,53 patients were male and 29 patients were female,ranging from 5 to 12,with an mean of 7 years old. The elbow joint function and Carrying angle were observed before and after treatment. The Flynn criteria was used to evaluate therapeutic effects. Results: All the patients were followed up,and the duration was six months. The average limitation angle of elbow joint was (2.8±3.7)°,and the Carrying angle was(12.7±2.2)°. According to Flynn clinical evaluation,80 patients got an excellent result,2 good. Conclusion: Treatment of child humeral supracondylar fracture with internal fixation using Kirschner wires and biodegradable tension bands through double small incisions is believed to be a good method,which has advantages of minimal trauma,reliable fixation,early exercises and rapid recovery.
