Musculoskeletal SE 07 MS - 01 What ’ s in your shoulder ? Current concepts of shoulder arthroplasty

TEACHING OBJECTIVES: To review the current concepts of shoulder arthroplasty. To review the normal post-operative appearance of shoulder arthroplasty including materials, design, and function. To review the imaging appearance of common complications. CONTENTS: Prosthesis material, design, and terminology Preoperative imaging assessment Normal post-operative imaging appearance Imaging findings of common complications CONCLUSION: Imaging evaluation of shoulder arthroplasty predominantly utilizes radiographs. The foundation of interpretation is the knowledge of the normal appearance of the many types of shoulder replacement hardware. From this knowledge of normal, the malfunctioning shoulder arthroplasty can be assessed. A standard approach to radiographic reporting should be undertaken. Some complications have a characteristic appearance that all radiologists should recognize.
