Modular hip replacement components offer numerous advantages, and the modular femoral component has become standard for contemporary total hip implants. Recent reports of mechanically assisted crevice corrosion (MACC) at the head-neck junction, and associated adverse local tissue reactions (ALTRs), have renewed concerns for complications attributed to modularity. This manuscript describes the diagnosis, prognosis, and treatment options for MACC and highlights how appropriate pre-revision evaluation and planning, in conjunction with meticulous surgical technique, should be followed to avoid complications and achieve optimal surgical outcomes. Future directions for research include biomechanical, clinical, and retrieval studies.
模块化髋关节置换组件具有诸多优点,模块化股骨组件已成为当代全髋关节植入物的标准配置。近期有关头颈交界处机械辅助缝隙腐蚀(MACC)及相关局部不良组织反应(ALTRs)的报道,再次引发了人们对模块化导致的并发症的担忧。本文描述了MACC的诊断、预后和治疗选择,并强调应如何结合细致的手术技术进行适当的翻修前评估和规划,以避免并发症并实现最佳手术效果。未来的研究方向包括生物力学、临床和取出物研究。
