Abstract
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.
