Glenohumeral osteoarthritis results in considerable disability, and affected patients have significant pain with acitivities and loss of motion.  Shoulder arthroplasty is the mainstay of operative treatment when conserative measures fail.  Good or excellent pain relief and restoration of function has been reported in 80% of those who have undergone hemiarthroplasty, and greater than 90% of patients with total shoulder arthroplasty.  Preoperative planning for shoulder arthroplasty with cross-sectional imaging is critical in selecting the correct prosthesis for long-term success. With this exhibit, the learner should gain knowledge of: Important glenohumeral and rotator cuff pathologies/findings as demonstrated on CT and MRI that result in the need for or attribute to the success of shoulder arthroplasties Different types of arthroplasties and what imaging findings help determine which prosthesis will be used. 

Introduction to shoulder osteoarthritis Review of the types of shoulder arthroplasties Familiarization of the pathologic findings that influence the choice of arthroplasty and their CT and MR imaging findings Pre-operative evaluation of the glenoid axis using 3D and 2D images through the true scapular axis
