E1177. Avoiding the Peek and Shriek: Mastering the Common Imaging Appearance and Complications of Uncommon Arthroplasties

Radiologists encounter arthroplasties frequently in practice given the widespread utilization of joint reconstruction for common joint disorders such as osteoarthritis and inflammatory arthritis involving the shoulder, knee, and hip. However, several surgical arthroplasties are increasingly utilized for small joints such as the elbow, ankle, and first carpometacarpal joint. Despite the increasing number of these arthroplasties, general radiologists often have a limited exposure to the normal imaging appearance and complications specific to these uncommon arthroplasties, leading to a “peek and shriek” phenomena when reviewing these cases.

Educational Goals / Teaching Points
The purpose of this educational exhibit is to familiarize radiologists with what normal elbow, ankle, and other uncommon arthroplasties should look like on imaging evaluation and explore unique features of each arthroplasty. Using case examples, this exhibit will review complications both unique to the arthroplasties as well as complications common to all arthroplasties.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit will review common indications leading to total elbow arthroplasties, total ankle arthroplasty, first carpometacarpal joint reconstruction, and silastic implants of the joints of the fingers. Additionally, we will review the unique components of each uncommon arthroplasty and how the components lend to the not only the structure but the function of the arthroplasty. Throughout the exhibit, we will review common imaging modalities used for postoperative assessment. Finally, we will explore common and uncommon complications through specific case examples.

Upon review of the educational exhibit, the radiologist should feel comfortable with the normal imaging appearance of these less common arthroplasties, be familiar with the different components of each arthroplasty, and identify complications of these uncommon arthroplasties.
