旋入式自锁髓内钉治疗下肢长骨骨折

目的总结旋入式自锁髓内钉治疗下肢长骨骨折的疗效。方法回顾性分析75例下肢骨折行旋入式自锁髓内钉治疗的临床资料,其中股骨干骨折29例,胫腓骨骨折46例。结果手术时间平均32(25～95)min,失血量平均65(20～350)ml,手术切口均一期愈合。69例平均随访13(7～25)月。骨折愈合时间平均4.3(3.5～15)月。3例发生延迟愈合。结论旋入式自锁髓内钉治疗下肢长骨骨折具有操作简单、创伤小、并发症少的优点,值得临床推广应用。

Internal Fixation of Rotary Self-locking Intramedullary Nail for Long Bone Fractures of Lower Extremity

Objective To summary the effect of rotary self-locking intramedullary nail in treatment of long bone fractures of lower extremity.Method 75 cases with long bone fractures of lower extremity performed internal fixation of rotary self-locking intramedullary nail were reviewed,including 29 of femoral shaft fracture and 46 of tibiofibular fracture.Results The average operation time was 32 minutes（ranged 25 to 95 minutes）,and the average blood loss was 65 ml（ranged 20 to 350） ml.All operative incisions were primary healing.69 cases were followed up for 7 to 25 months（average 13 months）.All fractures healed in 3.5 to 15 months（mean 4.3 months）.There was delayed fracture healing in 3 cases.Conclusion Internal fixation of rotary self-locking intramedullary nail is a simple and mini-invasive treatment for long bone fracture of lower extremity with less complication,and it deserve popularizing.
