Intervention model description: Patients undergoing reverse total shoulder arthroplasty or rotator cuff repair will be randomly assigned to two groups of immobilization method groups, namely abduction brace group and antirotation sling group.
Primary purpose: TREATMENT

Brief summary: To compare the functional and anatomical outcomes, and patient satisfaction and compliance between two different postoperative immobilization methods - abduction shoulder brace versus simple arm sling - following 2 common shoulder surgical procedures - rotator cuff repair (RCR) and reverse total shoulder arthroplasty (RTSA) through a prospective randomized clinical trial.

Detailed description: Scientific Background and Gaps Rotator cuff repair and reverse total shoulder arthroplasty are common procedures that aim to provide patients with less pain, better shoulder function, and overall improved quality of life. The number of these procedures performed annually has increased dramatically, and improved outcomes have been demonstrated for each intervention. Part of the success of these operations is dependent on postoperative rehabilitation and patient compliance. Shoulder immobilization versus early range of motion following each procedure has conflicting data, and recent studies have shown that the method of shoulder immobilization may not influence clinical outcomes. Previous studies, both clinical and biomechanical, have demonstrated that arm position following RCR impacts tension and stress placed on the repair, but few have shown whether this translates to improved patient outcomes. Some surgeons prefer simple arm slings for the above-named procedures, while others opt for the abduction brace. Multiple studies have shown the optimal shoulder position that places the least amount of tension on the RCR, or soft tissue envelope following RTSA, however there is no consensus as to the optimal postoperative immobilization technique that significantly affects patient outcomes. An antirotation sling is significantly cheaper than an abduction shoulder brace, and our anecdotal experience is that patients experience more difficulties with an abduction shoulder brace than an antirotation sling. Our study aims to determine whether patient outcomes are significantly affected by immobilization with an abduction brace or simple arm sling. Our hypothesis is that antirotation slings are no better or worse than shoulder abduction braces in regards to shoulder range of motion, satisfaction and compliance with the immobilization method, and pain.

Study Rationale There is a lack of evidence regarding abduction braces versus simple arm slings for postoperative immobilization following rotator cuff repair and reverse total shoulder arthroplasty. A better understanding of outcomes between each device will allow for more options available to the patient and surgeon, as well as a potential for decreased cost to the patient as there is a substantial difference in cost between the two devices.
