A retrograde intramedullary nail is an implant option for tibiotalocalcaneal arthrodesis because it provides mechanical strength and compression at the fusion site, while being less invasive to soft tissue. However, some fusion failures result in implant overloading, resulting in implant failure. The accumulated stress at the level of the subtalar joint will most likely cause implant breakage. It is challenging to remove the broken tibiotalocalcaneal nail's proximal part. Several surgical procedures for removing the broken tibiotalocalcaneal nail have been reported. In this article, we present a surgical technique for removing a broken tibiotalocalcaneal nail by punching out the proximal part of the broken nail using a prebent Steinmann pin. It has the advantage of being less invasive and not requiring any specific tools to punch out the nail.
逆行髓内钉是用于胫距跟关节融合术的一种植入物选择，因为它能在融合部位提供机械强度和加压作用，同时对软组织的侵袭性较小。然而，一些融合失败会导致植入物过载，进而导致植入物失效。距下关节水平处的累积应力很可能会导致植入物断裂。取出断裂的胫距跟钉近端部分具有挑战性。已有多篇报道介绍了几种取出断裂胫距跟钉的手术方法。在本文中，我们介绍一种手术技术，即使用预弯的斯氏针冲出断裂钉的近端部分来取出断裂的胫距跟钉。它具有侵袭性较小且无需任何特殊工具来冲出钉子的优点。
