Hip arthroplasty is a common and largely successful surgical procedure, often used for the treatment of advanced osteoarthritis. Imaging plays a key role in routine postoperative imaging surveillance as well as the evaluation of post-arthroplasty pain. Radiographs are the first-line imaging modality and may be followed by computed tomography (CT), ultrasound, and/or magnetic resonance imaging (MRI). Recent advancements in imaging techniques allow for metal artifact reduction on CT and MRI. A variety of complications can arise in the setting of arthroplasty: mechanical loosening, component wear-induced synovitis and osteolysis, adverse local tissue reaction, infection, periprosthetic fracture, implant dislocation and/or component displacement, tendinopathy, and neurovascular injury. This article reviews normal and abnormal imaging findings of hip arthroplasty.
髋关节置换术是一种常见且大多成功的外科手术,常用于治疗晚期骨关节炎。影像学在术后常规影像监测以及人工关节置换术后疼痛评估中起着关键作用。X线片是一线影像检查方式,之后可能会进行计算机断层扫描(CT)、超声和/或磁共振成像(MRI)。成像技术的最新进展有助于减少CT和MRI上的金属伪影。关节置换术可能会出现多种并发症:机械性松动、假体磨损导致的滑膜炎和骨溶解、局部组织不良反应、感染、假体周围骨折、植入物脱位和/或假体移位、肌腱病以及神经血管损伤。本文综述了髋关节置换术的正常和异常影像学表现。
