肱骨干骨折不愈合原因分析与治疗方法的探讨

目的：分析肱骨干骨折不愈合原因,探讨治疗方法。方法：随诊病例23例,了解初次治疗及本次术后1年以上情况。结果：除解剖因素外,均有治疗不当因素。如治疗方式失误,内固定材料欠,外固定与功能练习不正确等。经切开腹位,交锁髓内钉内固定,髂骨取骨植骨治疗这种陈旧骨折,骨折全部愈合,肩关节功能优良率68．3％,肘关节功能优良率72．7％,结论：Russell-Taylor(R-T)肱骨髓内钉用于肱骨干骨折不愈合或延迟愈合效果良好,关节功能恢复与初次治疗成功与否有关。

Study of the etiology of non union of humeral shaft fractures and its treatment methods

Objective*"To analyse the etiology of non union of humeral shaft fractures and to explore its treatment methods Methods*"The data of 23 patient with humeral shaft fractures after initial and the present treatment of over 1 year were studied.Results*"Apart from anatomic factor,the etiology of non union were related to incorrect treatment such as not suitable treatment method,non accurate selection of internal fixation apparatus and not exact external fixation or excise.After treating with open reduction,internal fixation of interlocking and bone grafting of iliac bone,the old fractures were cured and the excellent and good rate of shoulder joint function was 68 3%,elbow joint 72 7%.Conclusion*"Russell Taylor (R T) interlocking intramedullary nail is very effective in treating non union or delayed union of humeral shaft fractures and the recovery of joint function is related to the results of the initial treatment.
