Abstract

Gamma 3 rotation control lag screws (U-blade) are particularly useful when treating rotational and unstable fractures of the proximal femur. A 93-year-old woman who underwent closed reduction of a trochanteric fracture and internal fixation with a Gamma 3 nail rotation control lag screw. The patient presented with metal failure and U-blade bending following a fall occurring 4 weeks after surgery. Here, we present a case report summarizing removal of the failed lag screw.

摘要

Gamma 3旋转控制拉力螺钉（U型刀片）在治疗股骨近端旋转性和不稳定骨折时特别有用。一名93岁女性接受了转子间骨折闭合复位并使用Gamma 3带旋转控制拉力螺钉进行内固定。患者在术后4周跌倒后出现金属失效和U型刀片弯曲。在此，我们报告一例总结取出失效拉力螺钉的病例。
