S1otted锁式髓内钉治疗胫骨开放性骨折

作者应用Ｓ１ｏｔｅｄ锁式髓内钉治疗胫骨开放性骨折６４例，其中粉碎性骨折４７例。除２例失访，其余６２例骨折平均随访１．５年，骨折全部愈合。最终结果评分采用Ｊｏｈｎｅｒ－Ｗｒｕｈ评分标准，优６１例，良１例。６１例骨折平均愈合时间为５．６个月，１例延迟愈合（于术后１２个月愈合），术后晚期发生胫前浅表感染１例，未影响骨折愈合。所有病例未发现髓内钉断裂和锁钉断裂、脱出及拨钉后再骨折等情况。作者认为Ｓ１ｏｔｅｄ髓内钉可用于胫骨干的各段骨析（包括高位和低位骨折），对粉碎性骨折效果良好，且操作简单，不需特殊设备及器械，固定后能较好控制旋转，促进骨折愈合，是一种比较好的内固定方法。

Slotted Interlocking Intramedullary Nailing in the Treatment of Open Fractures of the Tibia.

Sixty four open fractures of the tibia had been treated with slotted interlocking intramedullary nailing by the authors.There were 47 comminuted fractures.Sixty two patients were followed up for an average of 18 months and evaluated according to the criteria of Johner and Wruh.In the open fractures,there were 61 assessed as excellent,l as good.The time for fracture union in 61 fractures averaged 5 6 months.Delayed union(12 months)developed in one patient.One of the patients was infected in the skin in front of the shin bone after operation but it did not affect the fracture healing.There were no broken nails and screws in this series.Furthermore,there were no refracture after nailing removed.The author concludes that slotted interlocking intramedullary nails is suitable for all kinds of shin bone fractures,especially for comminuted fracture.It is a simple operative method,which needs not any special equipment and medical appliances.There is low disturbance over the intramedullary circulation of tibia,and it can improve the fracture healing effectively.The author believes this is a good internal fixation.
