带锁髓内钉固定并植骨治疗肱骨干骨折不愈合疗效的临床分析

Clinical analysis of treatment of nonunion of humeral shaft fracture with interlocking intramedullary nailing and bone grafting

目的 :探讨带锁髓内钉治疗肱骨干骨折不愈合的疗效。方法 :回顾性分析肱骨干骨折不愈合 19例 ,用带锁髓内钉静力型固定骨折端并植骨。根据骨折部位生长情况改为动力型固定。并分析 1年以上的疗效。结果 :所有病例 6～ 8个月内均达骨性愈合。结论 :带锁髓内钉静力固定能有效控制有害的剪应力 ,同时对骨折有一定的加压作用 ,可提供早期坚强的内固定 。

Objective:To observe the effect of the nonunion of humeral shaft fracture treated by interlocking intramedullary nailing and bone grafting.Method:Ninteen cases of fracture nonunion of humeral shaft were manipulated to anatomic alignment and statically fixed with intramedullary interlocking nails.The effect over 1 year was evaluated.Result:All cases achieved a solid union with in (6～8) months.Conclusion:Intramedullary interlocking nails can provide not only the static fixation effectively control harmful shearstress,but also has some pressor function.It can provide firm internal fixation.So it is a perfect procedure for patients with hypertrophic nonunion of humeral shaft fracture.
