Primary total hip arthroplasties are expected to increase up to 174% by 2030 as the population ages. Unfortunately, complications associated with hip arthroplasties will also be on the rise. Therefore, it is important that we are familiar with these complications and recognize how they appear in several different modalities to provide relevant information to positively affect patient care.

Educational Goals / Teaching Points
It is our aim to describe primary vs revised hip arthroplasties as well as total vs hemi-hip arthroplasties. Their associated complications will be described using multimodal imaging findings such as x-ray, CT, ultrasound, and MRI. Metal artifact reduction techniques for CT and MRI will also be showcased.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Key issues include early and late complications of hip arthroplasties and their associated clinical signs and symptoms. We aim to describe perioperative hematoma, mechanical loosening, infection, polyethylene wear and particle disease, dislocations, stress shielding, periprosthetic fractures (including the Vancouver Classifications), metallosis/pseudotumor/aseptic lymphocyte-dominant vasculitis associated lesions and heterotopic ossifications (including Brooker classification).

As our population ages, the number of hip arthroplasty is projected to increase. Complications related to these procedures will also inevitably increase. Imaging plays a key role in routine postoperative imaging surveillance as well as the evaluation of post-arthroplasty pain. It is imperative that we are familiar with the appearance of these complications on multimodal imaging to positively affect patient care. We will provide a detailed display of early and late-stage complications using several different modalities.
