The predictability of outcomes with reverse shoulder arthroplasty (RSA), compared with hemiarthroplasty or open reduction and internal fixation, has led to its increased use in treating displaced three- and four-part proximal humerus fractures (PHFs) in patients older than 65 years. Although RSA was initially designed to restore humeral elevation in the absence of a functional rotator cuff, studies have shown improved patient-reported outcomes and range of motion in patients who achieve tuberosity union following surgery. Despite numerous advancements in implant design over the past decade, optimal strategies to maximize outcomes in PHFs remain debated. This article reviews indications, intraoperative decision making, implant selection, and surgical techniques to optimize outcomes for patients undergoing RSA for PHFs.

08:57Shoulder Exam I
Examination of the shoulder can be complex, because it actually consists of four separate joints: are the glenohumeral (GH) joint, the acromioclavicular (AC) joint, the sternoclavicular joint, and the scapulothoracic joint. The GH joint is primarily responsible for shoulder motion and is the most mobile joint in the body. It has been likened to a golf ball sitting on a tee and is prone to instability. It is held in place...
09:51Using Point of Care Ultrasound to Augment Acquisition of Physical Exam Skills: Knee and Shoulder
Point of Care Ultrasound or POCUS is easy to use, has enhanced mobility due to the smaller equipment needed, and may be carried out in a variety of settings. It is also far safer and cheaper than imaging techniques like computer tomography.
POCUS can be helpful when certain physical exam findings are difficult to appreciate by palpation, percussion, or auscultation and can facilitate learning elements of the cardiac, pulmonary,...

08:30Intra-articular Shoulder Injection for Reduction Following Shoulder Dislocation
The anterior shoulder dislocation is one of the most common joint dislocations seen in emergency settings. In anterior shoulder dislocation, the humeral head is displaced out of the glenohumeral joint in front of the scapular glenoid, resulting in a loss of the articulation between the arm and the rest of the shoulder. This can be caused by a fall onto an abducted, extended, and externally...
