Learning objectives Understand the various types of shoulder replacement.Review the role of imaging techniques (plain radiographs, CT, MRI, ultrasound, and scintigraphy) in assessing prostheses.Evaluate the usefulness and limitations of x ray and CT in shoulder replacement.Recognize normal and abnormal postoperative imaging findings, including signs of complications.
Read more Background Shoulder arthroplasty is an effective surgical procedure used to treat conditions like arthritis and fractures. Imaging plays a vital role before and after the surgery. Preoperative imaging, primarily through X-rays, helps assess the shoulder's anatomy and plan the surgery. CT scans give detailed insights into complex bone structures and are useful for evaluating bone quality. During the surgery, fluoroscopic imaging assists in real-time verification of component positioning. After the surgery, routine X-rays are taken to monitor healing and ensure proper implant alignment, while CT...
Read more Findings and procedure details A.- TYPES OF SHOULDER REPLACEMENT PROSTHESIS1.- Hemiarthroplasty Replacement Hemiarthroplasty: Replaces the humeral head with a stemmed prosthesis, used after proximal humerus fractures or when bone loss/osteoporosis prevents resurfacing implant fixation. Resurfacing Hemiarthroplasty: Suitable for moderate humeral head deformity with a preserved glenoid, in cases like osteoarthritis or avascular necrosis. 2.- Total Arthroplasty Total Shoulder Arthroplasty (TSA): Resurfaces/replaces the humeral head and glenoid, indicated for joint cartilage loss with an intact, functional rotator cuff. Reverse Shoulder Replacement: Reverses joint components, creating a constrained implant with a...
Read more Conclusion Imaging is essential for preoperative planning and evaluation of shoulder replacement. Preoperative imaging features and postoperative appearances of arthroplasty components are critical for surgical planning and early complication detection. Serial radiography is key for postoperative assessment, while CT, MR, and nuclear medicine complement radiographic findings by evaluating implant components and surrounding bone. X-rays serve as the initial modality, offering a straightforward assessment of bone structure, joint alignment, and deformities. CT scans provide detailed imaging of complex bony structures, which is especially useful for...
