Subscapularis integrity is critical after anatomic total shoulder arthroplasty, with failure leading to potential instability, loss of function, and revision surgery. The three well-described subscapularis mobilization techniques during total shoulder arthroplasty include tenotomy, peel, and lesser tuberosity osteotomy (LTO). While several comparative studies exist, the optimal approach remains controversial. LTO has been associated with the highest healing rates, but techniques and repair constructs are highly variable. The purpose of this article was to provide an overview of LTO with attention on radiographic assessment, repair options, and clinical outcomes.

Background: Prone positioning during endoscopic retrograde cholangiopancreatography (ERCP) can lead to post-procedure neck pain due to increased cervical spine stress and prolonged muscle stretching. This study aimed to evaluate the efficacy and satisfaction of an ergonomic wedge pillow for patients undergoing prone ERCP.

Methods: Patients indicated for ERCP were randomized 1:1 to a study group (with the pillow) or a control group.
