Intramedullary expanded self locking nail in treatment of femoral shaft fractures

目的观察髓内扩张自锁钉治疗股骨干骨折的效果。方法用髓内扩张自锁钉治疗股骨干骨折52例。其中股骨上1/3段8例,中1/3段35例,下1/3段9例。新鲜骨折46例,陈旧性骨折骨不连6例。结果随访5～32个月,平均15个月,50例正常愈合,2例延迟愈合。骨折愈合时间2～18个月,平均3.8个月。手术时间30～120min,平均80min,平均失血量390ml。结论髓内扩张自锁钉治疗股骨干骨折术中不需X线监视,骨折愈合率高,是一种较好的内固定方法。

Objective To investigate the clinical effects of intramedullary expanded self locking nail (IESN) in the treatment of femoral shaft fractures. Methods 52 cases of femoral shaft fractures were treated with the nailing procedure. Among them, 8 cases had fracture in the upper third of the femoral shaft, 35 cases in the middle third and 9 cases in the lower third. There were 46 cases of fresh fractures and 6 cases of old ones. Results The follow ups of 5 to 32 months (averaging 15 months) showed that 51 cases had union,with the union rate being 98%. The union time was from 3 months to 18 months (averaging 8 months). The operation time was from 30 minutes to 120 minutes (averaging 80 minutes). The loss of blood in operation averaged 390ml. Conclusion The intramedullary expanded self locking nail is a good internal fixation method to treat femoral shaft fractures, because it produces high union rate and does not need X ray monitoring during the operation.
