The incidence of complications following total hip arthroplasty is low, but due to the frequency of the procedure, they are quite commonly encountered and require appropriate investigation. Complications include aseptic loosening, infection, foreign body granulomatosis (osteolysis), adverse reactions to metal debris, periprosthetic fracture, heterotopic ossification, hardware failure, and a range of soft tissue complications, all of which may result in pain. Relevant imaging findings are illustrated and the role of various imaging modalities is reviewed. A suggested approach for the radiological investigation of each potential complication is outlined, based on our experience at a specialist referral unit.
全髋关节置换术后并发症的发生率较低，但由于该手术的实施频率较高，这些并发症相当常见，需要进行适当的检查。并发症包括无菌性松动、感染、异物肉芽肿（骨质溶解）、对金属碎屑的不良反应、假体周围骨折、异位骨化、内固定失败以及一系列软组织并发症，所有这些都可能导致疼痛。文中展示了相关的影像学表现，并回顾了各种成像方式的作用。基于我们在一家专科转诊单位的经验，概述了针对每种潜在并发症进行放射学检查的建议方法。
