应用扩髓交锁髓内钉治疗胫骨不稳定性骨折

目的 探讨扩髓交锁髓内钉治疗胫骨不稳定性骨折的治疗效果。方法 对42例胫骨不稳定性骨折患行扩髓交锁髓内钉固定，闭合性骨折22例，开放性骨折20例，均应用静力性固定。结果 平均随访时间12个月，采用Johner—Wruh评分标准，治疗结果：优32例，良8例，一般2例。骨折平均愈合时间：闭合性骨折15周，开放性骨折19周，3例延迟愈合，无深部感染、骨髓炎、畸形愈合及骨不连发生。结论 扩髓交锁髓内钉是治疗胫骨不稳定性骨折较理想的方法，可促进骨折愈合，并发症少。

Treatment of unstable tibial fractures with reamed interlocking intramedullary nail

objective To study the therapeutic effect of reamed interlocking intramedullary nail for unstable tibial fractures. Methods Forty two consecutive patients with unstable tibial fracture, including 22 closed and 20 open fractures, were treated with reamed interlocking intramedullary nail. All fractures were fixed statically.The mean duration of follow up was 12 months and was evaluated with Johner& Wruhs' criteria. Results The outcome was excellent in 32 cases, good in 8 cases and fair in 2 cases. The time for fracture union averaged 15 weeks in closed fractures and 19 weeks in open fractures. Delayed union occurred in 3 patients. No deep part infection, osteomyelitis, malunion, nonunion and nail failur were observed.Conclusion Reamed interlocking intramedullary nail is an ideal internal fixation method for treatment of unstable tibial fracture, which can improve the union of fracture with less complications.
