We present a case of a rare low-energy catastrophic failure of a carbon-fiber-reinforced polyetheretherketone tibial intramedullary nail at 10 weeks after placement in a 36-year-old man. We describe our experience with extraction of the device.
Carbon-fiber composite implants are approved for clinical use in orthopaedic trauma applications. The rare failure of carbon-fiber implants presents unique challenges because typical extraction techniques cannot be used. With the patient described herein, a terminally threaded guidewire was used to cannulate and extract the distal segment of the nail.
我们报告了一例罕见的低能量灾难性事件，一名36岁男性在植入碳纤维增强聚醚醚酮胫骨髓内钉10周后，该髓内钉发生断裂。我们描述了取出该装置的经验。
碳纤维复合植入物已被批准用于骨科创伤的临床应用。碳纤维植入物的罕见断裂带来了独特的挑战，因为无法使用典型的取出技术。对于本文所述的患者，使用了末端带螺纹的导丝插入并取出髓内钉的远端部分。
