Hardware removal in a healed intertrochanteric fracture in elderly, which is not a routine procedure, should be needed in the case of irritable hardware. The reports of refracture after hardware removal can be seen as sparse in current literature, which are focused to secondary femoral neck fracture after removal of the lag screw or blade. We experienced a case of the intertrochanteric refracture and varus collapse after the PFNA removal in a healed fracture, treated with valgus trochanteric osteotomy and angled blade plate fixation. The PFNA is an innovative device for the treatment of the trochanteric fracture; however, the complications after removal never end. Therefore, the removal from healed fracture in elderly who have osteoporosis should not be recommended unless intractable pain had persisted.

股骨转子间骨折愈合后切除 PFNA 后的再骨折：病例报告

对于易激惹的硬件，应该需要在老年人股骨转子间骨折愈合时移除硬件，这不是常规程序。目前文献中关于硬件移除后再次骨折的报道很少，主要集中在拉力螺钉或刀片移除后的继发性股骨颈骨折。我们经历了一例在愈合的骨折中取出 PFNA 后转子间再骨折和内翻塌陷的病例，采用外翻转子截骨术和成角度的刀片板固定治疗。PFNA 是一种用于治疗大转子骨折的创新设备；然而，移除后的并发症永远不会结束。因此，除非顽固性疼痛持续存在，否则不应建议患有骨质疏松症的老年人从愈合骨折中取出。
