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

[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.
