Abstract

We report two cases of implant removal failure following internal fixation of femoral neck fractures using the Prima Hip Screw Side Plate (PHS-SP) system.

Case 1 involved an 80-year-old woman with stripped screw heads, which prevented standard screw removal. The femoral neck was osteotomized, and the screws were severed to allow removal of the plate.

Case 2 involved a 50-year-old man in whom a screw was firmly lodged in the barrel of the implant, making extraction impossible. The protruding screw was excised, and a second operation was later performed to cut the femoral neck and remove the implant.

Conclusion: In both cases, implant removal required osteotomy of the femoral neck and mechanical destruction of the screws. These cases highlight the potential for implant removal failure in locking plate systems, and the importance of preoperative planning and patient counseling.

Prima髋侧钢板系统切开复位内固定治疗股骨颈骨折后假体取出失败2例

我们报告两例使用Prima髋关节螺钉侧板（PHS-SP）系统内固定股骨颈骨折后取出假体失败的病例。病例1涉及一名80岁妇女，螺钉头脱落，无法正常取出螺钉。股骨颈被截骨，螺钉被切断以便取出钢板。病例2涉及一名50岁的男性，其中一颗螺钉牢牢地卡在种植体的筒状体中，无法拔出。切除突出螺钉，随后进行第二次手术切除股骨颈并取出植入物。结论：在这两种情况下，假体取出需要股骨颈截骨和机械破坏螺钉。这些病例强调了锁定钢板系统中植入物取出失败的可能性，以及术前计划和患者咨询的重要性。

期刊介绍： Trauma Case Reports is the only open access, online journal dedicated to the publication of case reports in all aspects of trauma care and accident surgery. Case reports on all aspects of trauma management, surgical procedures for all tissues, resuscitation, anaesthesia and trauma and tissue healing will be considered for publication by the international editorial team and will be subject to peer review. Bringing together these cases from an international authorship will shed light on surgical problems and help in their effective resolution.
