计算机导航下交锁髓内钉的远端螺钉交锁

Computer navigation for distal locking in the interlocking intramedullary nailing

目的 报道计算机导航技术应用于交锁髓内钉远端交锁螺钉固定效果。方法 6例股骨、4例胫腓骨骨折 ,交锁髓内钉置入后 ,只需要一次C臂X线机透视定位 ,在计算机导航下完成远端交锁螺钉的固定。结果 10例全部在导航下完成交锁髓内钉的远端交锁 ,平均透视时间为 10s。结论 计算机导航手术用于交锁髓内钉的远端固定十分有效 ,可避免机械引导器的误差。

Objective To investigate the effect of computer navigation for distal locking in the interlocking intra-medullary nailing. Methods 6 cases of femoral fractures and 4 tibial fractures were enrolled. After insertion of the nail, only under once C-arm localization, the distal locking was completed with computer navigation.Results 10 cases obtained successful distal locking computer navigation. The fluoroscopy time was 10 s on average. Conclusion It is very effective to performed distal locking in the interlocking intramedullary nailing with computer navigation, which avoids the deviation of mechanical target device.
