Anterior Shoulder Instability

The anatomy of the glenohumeral joint prioritizes mobility at the expense of stability and thus predisposes it to injury through dislocation. This article discusses the anatomical basis for instability and how it translates into patterns of injury, focusing on anterior instability. We suggest an approach to imaging the unstable shoulder and examine the imaging features seen in the context of anterior instability, along with consideration of postoperative appearances.
