Ceramic liner fracture in ceramic on ceramic Total hip arthoplasty: A case report

摘要

Introduction Revision rates of total hip arthoplasty have decreased after introducing total hip arthroplasty using ceramic component due to reduce wear and osteolysis. Case report 29?year old male case of bilateral hip avascular necrosis operated for bilateral hip THA presented 30 months after with complaint of squeaking, x-ray showing left ceramic liner fracture without any history of trauma. Revision of ceramic liner and head with ceramic on polyethylene was done. Discussion and conclusion Ceramic on ceramic articulation has the lowest wear rate among various articulations. However, there is a concern about ceramic implant fracture; therefore ceramic with polyethylene bearing could be a good choice.
