A 17-year-old adolescent boy presented 2 months after initial intramedullary nail (IMN) fixation of a comminuted subtrochanteric fracture with refracture at the previous site and approximately 20° varus angulation of the nail. The bent femoral nail was successfully extracted using an open technique using Lohman bone-holding clamps and a broad plate. At the 1-year follow-up, fracture union was achieved.
Removal of a deformed IMN is rare. No standardized protocol exists in guiding orthopaedic surgeons. A thorough review of techniques is discussed on this unusual complication.
一名 17 岁青少年男性，初次接受髓内钉（IMN）固定粉碎性转子下骨折 2 个月后，在原骨折部位发生再骨折，且钉出现约 20°的内翻成角。采用开放式技术，使用 Lohman 骨夹持钳和宽钢板成功取出弯曲的股骨钉。1 年随访时，骨折愈合。
变形的 IMN 取出较为少见，目前尚无指导骨科医生的标准化方案。对这种不常见的并发症进行了技术的深入探讨。
