摘　　要：目的　观察髓内扩张自锁钉治疗股骨干骨折的临床疗效。方法　回顾性分析 1998年 10月～ 2 0 0 0年 3月髓内扩张自锁钉治疗闭合性股骨干骨折 32例资料。所有手术均采用切开复位 ,置入髓内扩张自锁钉固定治疗。术后 1周即开始临近关节功能活动和患肢 10～ 15 kg的部分负重。结果　经 4～ 2 2月 (平均 13.2月 )随访 ,32例骨折患者 3～ 6个月内临床骨愈合。1例术后 4个月再次外伤 ,继续固定 3月达临床骨愈合。所有患者术后临近关节的功能恢复达正常的 90 %以上。结论　 (1)髓内扩张自锁钉及配套器械设计合理 ,手术操作简便 ,避免术中 X线辐射损害 ;(2 )不须完全扩髓 ,对局部血运破坏小 ,有利于骨折愈合 ;(3)其抗骨折部位扭转及短缩能力可靠 ,避免应力集中 。Objective To observe the clinical effect of intramedullary expended self loaking nail in the treatment of femoral shaft fracture.Methods Thirty two cases of femoral shaft fracture were treated with the intramedullary expended self loaking nail from october,1981 to March,2000 were analyzed retrospectively.All of them were operated with open correcting dislocation and nailing procedure.A week after operation,the patient was asked to begin function exercise of the adjacent joints and weight training(10～15 kg)with the injured limb.Results After follow up of 4～22 months(average 13.2 months),all of the fracture had union in 3～6 months.A case had trauma once more 4 months after operation,which were healed after continuous internal fixation for 3 months.After operations,among all cases the adjacent joints' effect recovered partly to more than 90 percent.Conclusion (1) The intramedullary expended self loaking nail is well designed,easy to operate,which can avoid X ray's harm during the operation.(2)Expension of bone merrow completely is not needed,which would reduce the impartment of local circulation and promote the fracture healing.(3)The intramedullary expended self loaking nail has reliable ability of resisting caricature,shortening of fracture,which is beneficial the functional excise and the weight training of affected limb.
