半交叉钢针治疗儿童肱骨髁上骨折预防肘内翻的回顾性分析

Half Cross Pin Retrospective Analysis on the Treatment of Cubitus Varus Supracondylar Humeral Fractures in Children

目的：总结半交叉钢针在儿童肱骨髁上骨折的应用,并评价其预防后肘内翻的疗效.方法：对1180例病例行闭合复位半交叉钢针内固定治疗,术中注意纠正断端尺偏、尺倾、尺嵌移位及旋转移位.术后患者卧位时伤肢置于肩关节外展外旋、肘关节屈曲外翻、前臂旋后位,站位时上臂置于胸壁外侧,肘屈曲外翻、前臂旋后位.结果：随访时间3～36个月,平均为24个月,优良率达98％.结论：预防儿童肱骨髁上骨折肘内翻的发生,应强调手法整复的技能,术中应矫正骨折远端的尺偏、尺倾及旋转,术后应重视肢体位置的摆放.

Objective： Summary of application of semi cross pin fracture in children with supracondylar humerus, and to evaluate its efficacy in the prevention of cubitus varus after. Methods： On 1180 patients with dosed reduction and half cross pin fixation, Care should be taken to correct the broken end of ulnar deviation, ulnar deviation, ulnar block shift and rotation displacement. Postoperative patients lie when the injured limb on the shoulder joint abduction and external rotation, elbow flexion eversion, forearm supination position, arm placed in the lateral chest wall, elbow flexion, supination eversion of forearm. Results： The follow - up time was 3 - 36 months, An average of 24 months, The excellent and good rate was 98%. Conclusion： Prevention of humeral supracondylar fracture in children. The inci- dence of cubitus varus, should emphasize the manipulation skills. We should correct intraoperative fracture of the distal ulnar deviation, ulnar tilt and rotation. Postoperative should be put attention to body position
