改良克氏针治疗锁骨骨折

Treating Clavicular Fracture by Improved Kel′s Needle

目的 :探讨克氏针治疗锁骨骨折的并发症及其原因 ,并对克氏针进行改良。方法 :将克氏针针头 1cm加工成螺纹状 ,再将针头做轻度弯曲 ,治疗锁骨骨折病人。结果 :全部病例均得到随访 ,骨折均愈合 ,平均愈合时间 3个月 ,治疗锁骨骨折病人 37例 ,优良率为 97.3%。结论 :改良克氏针符合生物力学原理 ,改良后增加了摩擦力 ,减少退针 ,增加了稳定性 ,有利于骨折的愈合 ,且操作简单 。

Objective To research the efficiency of clavicular fracture treatment by improved Kel′s needle.Methods The surface of 1cm of apical segment of Kel′s needle was processed into spiral stria and somewhat arched,then used to fix the fractured clavicula.37 cases of cavicular fracture were treated with the improved Kel′s needle and followed up.Results All cases were cured well.The average period of cure is 3 months.Good and excellent rate of curatice effect is 97.3%.Conclusion The improved Kel′s needle accords with biomechanical characteristic of clavicle,it can increase the stability and is of value to cure the fracture and easy to operate.
