To report our experience with a novel alternative method of freehand interlocking of intramedullary nails. This method requires the use of only anterior-posterior image intensification and an intramedullary guide wire to verify screw placement. Our results are compared with historical results in the literature.
A total of 815 patients were treated using this technique from January 2008 to December 2012; 603 patients had fractures of the tibia and 212 had fractures of the femur.
The mean duration of surgery for tibial shaft fractures was 55.6 minutes (range 42-60 minutes) and that for fractures of the femur was 78 minutes (range 50-90 minutes). The mean time for each distal locking was 3.8 minutes (2.5-5.1 minutes), with 7.65 seconds of exposure to radiation during each block.
The surgical technique is simple, easy and reproducible. Mean time of surgery and radiation exposure was less than that in the literature. A comparative study should be performed.
报告我们使用一种新型徒手交锁髓内钉的替代方法的经验。该方法仅需使用前后位影像增强器和一根髓内导丝来验证螺钉置入情况。我们将结果与文献中的既往结果进行比较。
2008年1月至2012年12月期间，共有815例患者采用该技术进行治疗；其中603例为胫骨骨折患者，212例为股骨骨折患者。
胫骨干骨折的平均手术时长为55.6分钟（范围42 - 60分钟），股骨骨折的平均手术时长为78分钟（范围50 - 90分钟）。每次远端交锁的平均时间为3.8分钟（2.5 - 5.1分钟），每次透视期间的辐射暴露时间为7.65秒。
该手术技术简单、易行且可重复。平均手术时间和辐射暴露时间均低于文献中的报道。应进行一项对比研究。
