After viewing this exhibit the reader will be able to:  1. Explain the pathophysiology of anterior glenohumeral joint instability 2. Accurately quantify the extent of glenoid bone loss using Computed Tomography (CT) and Magnetic Resonance Imaging (MRI)  3. Understand the clinical ramifications associated with the extent of glenoid bone loss  4. Understand the multiple reconstructive surgical techniques for correcting anterior glenohumeral instability with emphasis on the Latarjet procedure (coracoid transfer to glenoid) and its normal and abnormal postoperative imaging appearance
