Learning objectives To describe the different types of elbow replacement. To analyze the role of imaging techniques (plain radiograph, CT, MR, US, scintigraphy) in evaluating elbow prostheses. To present images of plain radiographs and CT of elbow replacements, emphasizing usefulness and limitations. To review normal and abnormal postoperative imaging findings and signs of complications.
Read more Background Although not so frequent as prostheses in other articular areas, elbow replacement is becoming an accepted technique in treating several entities. We review elbow replacement, highlighting key imaging findings and parameters useful for the surgeon and correlating images with clinical considerations and functional outcomes.
Read more Findings and procedure details A.- INDICATIONS: 1.- Total elbow arthroplasty Classic Indication Inflammatory arthropathies, such as rheumatoid arthritis, constitute a classical indication for elbow prostheses. Newer indications: Primary or posttraumatic osteoarthritis. Fracture nonunion. Comminuted fractures of the elbow. Postoperative resection of a neoplasm. [fig 1] 2.- Radial head replacement Comminuted Mason types III and IV radial head fracture. Radial head fracture with medial or lateral ulnar collateral ligament dysfunction. Monteggia variants. Olecranon and coronoid process fractures. Interosseous membrane disruption. Treatment of osteoarthritis. [fig 2] B.- CONTRAINDICATIONS:Absolute contraindications Active infection. Inability or unwillingness of the patient to comply with the short- or long-term activity...
Read more Conclusion Elbow arthroplasty is a better treatment option for advanced-stage rheumatoid arthritis, severe joint diseases, and elbow trauma. Imaging is essential in preoperative planning and evaluation of elbow replacement. The radiologist should be familiar with normal and abnormal images and the presentation of complications in different imaging techniques. Serial radiography is integral to the postoperative evaluation of elbow replacement. CT, MR, and nuclear medicine complement postoperative imaging evaluation of implant components and surrounding bone, specifically regarding occult or equivocal radiographic findings.
