双矩形钉内固定治疗肱骨干骨折

Treatment of Humerus Fracture by Internal Fixation of Double Rectangle Shape Nails

目的 分析和评估双矩形钉内固定治疗肱骨干骨折的效果。方法 应用双矩形钉内固定治疗 42例肱骨干骨折 ;采用钢板螺丝钉内固定治疗 46例肱骨干骨折 ,观察疗效并进行比较。结果 所有病例随访 6～ 2 4(平均 12 )个月。手术耗时及出血量矩形钉组明显少于钢板组 (P <0 .0 5 )。矩形钉组及钢板组骨折愈合优良率分别为 95 .2 %及 80 .5 % (P >0 .0 5 ) ,肩肘关节活动度优良率分别为 88.1%及 84.8% (P <0 .0 5 ) ,术中桡神经误伤分别为 0例及 5例 (P <0 .0 5 )。结论 应用双矩形钉内固定治疗肱骨干骨折具有操作简便 ,手术创伤小 ,固定可靠等优点 ,骨折愈合率高 ,术后可早期活动关节 ,并发症少。值得应用和推广。

Objective To analyze and evaluate the efficacy of the double shape rectangle nail in the treatment of humerus fracture.Method 42 cases of humerus shaft fracture were treated with the double rectangle nails,and 46 cases of humerus fracture were treated with the steel plate.Results All cases were followed up from 6 to 24 months with an average of 12 months.The operation time and blooding volume in the rectangle nail group were less than those in the steel plate group( P <0.05).95.2% of the fractures healed up well in the rectangle nail group,80.5% in the steel plate group.There were 0 and 5 cases of radial nerve damage during the operation in the rectangle nail group and the steel plate group respectively.There were significant differences above all between two groups( P <0.05).88.1% of the cases have good functions of shoulder and elbow joint in the rectangle nail group,84.8% in the steel plate group.There were no significant differences between two groups( P >0.05).Conclusions Double rectangle shape nails had obvious advantage of simpler manipulation,less trauma,reliable fixation,high rate of fracture healing.It is a recommendable method for the treatment of humerus fracture.
