337 Accuracy of Landmark-Guided Glenohumeral Intra-Articular Injections in Patients With Anterior Shoulder Dislocations

The shoulder joint is the most commonly dislocated joint and accounts for more than 70,000 emergency department (ED) visits per year in the United States alone. Current evidence suggests that intra-articular injection of the shoulder with local anesthetic agents can provide adequate analgesia to facilitate reduction and obviate the need for more resource intensive methods such as procedural sedation. However, studies have not determined the rate at which landmark-guided shoulder joint injections (LGI) truly deposit local anesthetic into the joint space.
