交锁髓内钉治疗胫骨骨干骨折骨不连

Treatment of nonunion of tibia shaft after fracture with interlocking intramedallary nail

目的探讨交锁髓内钉在胫骨骨干骨折骨不连治疗中的应用方法,并对其疗效进行评估。方法2000年7月～2004年3月应用交锁髓内钉治疗胫骨干骨折骨不连62例。结果该组术后随访8个月～4.4年(平均2.6年),除1例因术后过早下地活动,导致髓内钉折断,需再次手术,其余病例均愈合,愈合率98.39%。结论交锁髓内钉治疗胫骨干骨折骨不连,具有固定牢靠,有效维持肢体长度,早期活动,有利于关节功能恢复,并发症少等优点。

[Objective] To explore retrospectively the using techniques of interlocking intramedaUary nail in the treatment of nonunion of tibia shaft after fracture and evaluate the outcomes of the treatment. [Methods] Sixty two cases suffered from nonunion of tibia shaft after fracture between July 2000 and March 2004 were treated by interlocking intramedaUary nail protocol. [Results] After an average 2.6 years of follow-up ranging from 8 months to 4.4 years, 61/62 cases had achieved a osteal healing of the nonunion, the healing rate was 98.39% and 1/62 cases had exchanged another interlocking intramedaUary nail protocol due to walking burdened too early lead to the break of interlocking intramedaUary nail. [Conclusion] Interlocking intramedallary nail protocol have some advantages, such as providing finn fixation, feasible early activity, effective maintaining the limb length, benefiting the recover of the joint function, less complications in the treatment of nonunion of tibia shaft after fracture.
