[摘要] 目的 研究內固定物失效的原因及防治對策。方法 回顧性研究分析30例內固定物失效病例。結果 不同骨折部位、骨折類型、內固定方式發生內固定物失效機率不同。負重較多的股骨、脛骨發生內固定物斷裂、松動率較高,約占56.3%,合并開放性及粉碎型骨折約占53.3%,鋼板固定方式約占53.3%。結論 內固定物失效原因眾多,與骨折發生部位、骨折類型、內固定物選擇方式、術中的具體操作及術后功能鍛煉、外固定物的輔助有密切關系。

[Abstract] ObjectiveTo research the reasons of invalid fixation in limb fractures and the prevention and cure counterplan. MethodsThirty cases of limb fracture with lossen or broken internal fixators were reviewed admitted from January 1998 to March 2007. ResultsDifferent kinds of fracture site,fracture type,the way of internal fixation takes place invalid fixation rats is dissimilarity the weigth loading site such as femur and tibia result in invalid fixation more than the other sites,about account 56.3%.complicating the compound fractures and syntripsis share 53.3%,the steel-plate fixation cases share 53.3%. ConclusionThe reasons of invalid fixation in limb fractures is numerous,it is close contact with the fracture site,fracture type,the way of internal fixation,operative procedure,postopration functional exercise and essential external fixation.

現今骨折的治療逐漸傾向手術治療,內固定術由于其復位準確、固定堅強、能早期下地活動、生活質量較高等眾多優勢而被普及推廣,但是隨之伴隨的內固定物斷裂、松動、再骨折等并發癥亦日漸增多,日益受到重視及反思,本文通過病例回顧性研究,旨在分析內固定物失效原因及有效防治對策。
