ABSTRACT
Shoulder instability is common, especially anterior subluxation and dislocation. The
sequelae are well seen on magnetic resonance imaging and include tears of the labrum,
glenohumeral ligaments, capsule, tendons, and muscles. This article seeks to discuss
and illustrate common pitfalls and lesions associated with instability. Anatomic and
technical considerations, including the use of magnetic resonance arthrography, are
also addressed.
