目的探讨外固定架在创伤骨科中的应用疗效。方法选取100例四肢长骨骨折患者随机分成观察组和对照组两组，每组各50例。对照组实行内固定治疗，观察组实行外固定架治疗，对比两组疗效。结果观察组手术时间、术中出血量、骨折愈合时间、术后并发症发生率等均低于对照组(<0.05)。结论外固定支架术治疗普通创伤骨折的疗效值得肯定，效果优于常规内固定治疗术，术后并发症发生率低，可行推广应用。“,”Objective To investigate the clinical effect of external fixator in the treatment of trauma department of orthopedics.Methods 100 cases of bone fracture were randomly divided into observation group and control group two groups,50 cases in each group.The control group was treated with internal fixation,the observation group was treated with external fixation,and the efficacy of the two groups was compared.Results The operation time, bleeding volume,fracture healing time and postoperative complication rate of the observation group were lower than those of the control group( <0.05). Conclusion The clinical effect of external fixation for the treatment of common trauma fracture is worthy of recognition,and the effect is better than that of conventional internal fixation,and the postoperative complication rate is low,and it can be popularized and applied.
