Component dissociation secondary to trunnionosis is rare, and its causes are multifactorial. It is a major complication of total hip replacement, in most cases requiring revision arthroplasty. In this paper, we present a case of taper/head modular interface dissociation in a metal-on-metal total hip replacement. We review the literature of both trunnionosis, as well as a systematic review of modular dissociation of the femoral component in total hip arthroplasty, identifying commonalities with our own case.
由于股骨柄腐蚀导致的部件分离很少见,其病因是多因素的。它是全髋关节置换术的一种主要并发症,在大多数情况下需要进行翻修关节成形术。在本文中,我们报告了一例金属对金属全髋关节置换术中锥度/股骨头模块化界面分离的病例。我们回顾了股骨柄腐蚀的相关文献,以及对全髋关节置换术中股骨部件模块化分离的系统综述,确定了与我们自己病例的共性。
