An 81-year-old female was treated for a pertrochanteric multifragmentary fracture of the proximal femur with a third-generation Gamma nail. After 3 months she presented herself again with acute pain and inability to bear weight on the leg. Radiographs showed medial migration of the lag screw. She was treated with a total hip arthroplasty, after which she was successfully discharged. In this case report the possible causes of this late and unusual complication are discussed.

一名81岁女性因股骨近端转子间多段骨折接受第三代伽马钉治疗。3个月后，她再次出现剧痛且无法负重行走。X线片显示拉力螺钉向内侧移位。她接受了全髋关节置换术，术后顺利出院。本病例报告讨论了这种晚期罕见并发症的可能原因。
