带锁髓内钉治疗股骨、股骨干骨折的临床应用

目的 带锁髓内钉治疗股骨、胫骨干骨折临床应用研究。方法 应用带锁髓内钉治疗股骨、胫骨干骨折104例。结果 闭合复位穿钉内固定术后6－10周愈合，切开复位内固定8－12周愈合，48周后拔出内固定物。无断钉、骨折延迟愈合或不愈合、感染、脂肪栓塞、关节僵硬等并发症发生。104例均获随访，平均随访20个月，无1例再次骨折。结论 带锁髓内钉内固定治疗股骨、胫骨干骨折与传统钢板螺丝钉内固定相比，具有固定牢固，防止骨折端扭转、分离，术后不需要外固定支持，能早期负重行走，骨折愈合率高，治疗效果可靠的优点。

Clinical use of intramedullary interlocking nail in treatment of femoral, tibial fractures

Objective To study the clinical use of intramedullary interlocking nail in treatment of femoral and tibial fractures. Methods104 cases of femoral or tibial fractures were treated with intramedullary interlocking nails.Results The close and open reduction fractures had healed 6 10 and 8 12 weeks after surgery, and the fixation nails were taken out after 48 weeks. No broken nail, no delayed or nonunion, no infection, no fat embolism, no stiff joint occurred, All cases were followed up and the average following was 20 months without fracture.Conclusion The intramedullary interlocking nail had obvious advantage of reliable fixation, rotation and separation prevention, no need of external fixation support, high rate of fracture healing and allowance of early walk without support.
