Hip arthroplasty (HA) is a frequently used procedure with high success rates, but 7% to 27% of the patients complain of persistent postsurgical pain 1 to 4 years post-operation. HA complications depend on the post-operative delay, the type of material used, the patient's characteristics, and the surgical approach. Radiographs are still the first imaging modality used for routine follow-up, in asymptomatic and painful cases. CT and MRI used to suffer from metallic artifacts but are nowadays central in HA complications diagnosis, both having their advantages and drawbacks. Additionally, there is no consensus on the optimal imaging workup for HA complication diagnosis, which may have an impact on patient management. After a brief reminder about the different types of prostheses, this article reviews their normal and pathologic appearance, according to each imaging modality, keeping in mind that few abnormalities might be present, not anyone requiring treatment, depending on the clinical scenario. A diagnostic imaging workup is also discussed, to aid the therapist in his imaging studies prescription and the radiologist in their practical aspects.
髋关节置换术（HA）是一种常用手术，成功率较高，但7%至27%的患者在术后1至4年抱怨存在持续性术后疼痛。HA并发症取决于术后延迟时间、所用材料类型、患者特征以及手术方式。对于无症状和疼痛病例，X线片仍是常规随访中首先使用的成像方式。CT和MRI过去受金属伪影影响，但如今在HA并发症诊断中起着核心作用，两者都有各自的优缺点。此外，对于HA并发症诊断的最佳成像检查方法尚无共识，这可能会对患者管理产生影响。在简要回顾不同类型假体后，本文根据每种成像方式综述了它们的正常和病理表现，要记住，根据临床情况，可能存在一些异常，但并非所有异常都需要治疗。还讨论了诊断性成像检查方法，以协助治疗师进行成像研究的处方开具，并帮助放射科医生了解实际操作方面的问题。
