Distal third tibial fractures are prone to non-union following tibial nail insertion. The purpose of this study was to assess the union of distal third tibial fractures in patients who have undergone intra-medullary (IM) tibial nailing with one versus two distal locking screws. Sixty-five patients who had intramedullary tibial nail fixation were retrospectively analysed. Our results showed that 80% of non-unions in distal third fractures had only one distal locking screw compared to 20% who had two distal locking screws. This is statistically significant (p<0.01). We therefore conclude that two distal locking screws are essential for distal third fractures.
胫骨远端三分之一骨折在插入胫骨髓内钉后容易发生骨不连。本研究的目的是评估接受单枚与双枚远端锁定螺钉的胫骨髓内钉固定的患者中胫骨远端三分之一骨折的愈合情况。对65例行胫骨髓内钉固定的患者进行回顾性分析。我们的结果显示,远端三分之一骨折的骨不连患者中,80%仅使用了一枚远端锁定螺钉,而使用两枚远端锁定螺钉的患者占20%。这具有统计学意义(p<0.01)。因此,我们得出结论,对于远端三分之一骨折,两枚远端锁定螺钉是必不可少的。
