This paper describes two different techniques for removal of broken Precice Stryde intramedullary bone lengthening nails, which unlike trauma nails are solid containing mechanical components. Consequently, surgeons face unique challenges when these implants brake within medullary canal. Here, we present our surgical approach for removal of three broken implants. In one patient (46kg) both Ø10mm femoral Stryde implants (max. weight allowance 68kg) broke through the proximal locking screw hole preoperatively on the right side and intraoperatively on the left side (413 and 504 days after index surgery respectively). The third Ø11.5 femoral nail broke through the area containing the magnet (55kg patient, 325 days after index surgery). LEVEL OF EVIDENCE: IV.
本文描述了两种不同的取出断裂的 Precice Stryde 髓内骨延长钉的技术，与创伤钉不同，这些钉子是实心的，含有机械部件。因此，当这些植入物在髓腔内断裂时，外科医生面临着独特的挑战。在这里，我们介绍了我们移除三个断裂植入物的手术方法。在一名 46 公斤重的患者中，右侧的两根 10 毫米股骨 Stryde 植入物（最大允许重量 68 公斤）在术前和左侧的植入物在术中（分别在指数手术后的 413 天和 504 天）穿过近端锁定螺钉孔。第三根 11.5 毫米股骨钉在含有磁铁的区域断裂（55 公斤患者，指数手术后 325 天）。证据水平：IV。
