A problem arose when the reamed tibia nail was replaced by a massive unreamed tibia nail. Of the nail fractures, it is difficult to remove the distal fragment from the medullary cavity. It may also happen that the connecting screw between the insertion handle and the nail breaks off at the edge of the implant, which complicates removal of the nail. The authors have developed a technique for removing the implant without having to saw a fissure in the marrow. A concave instrument is slid over the part of the nail left behind after which the two are connected by means of a K wire. This method has been successfully applied in two patients.
当扩髓胫骨髓内钉被大量非扩髓胫骨髓内钉取代时出现了一个问题。在髓内钉骨折的情况下,很难从髓腔中取出远端碎片。也可能发生插入手柄与髓内钉之间的连接螺钉在植入物边缘处折断的情况,这使得取出髓内钉变得复杂。作者开发了一种无需在骨髓中锯开裂缝就能取出植入物的技术。将一个凹形器械滑过残留的髓内钉部分,之后通过一根克氏针将二者连接起来。该方法已在两名患者中成功应用。
