MR Arthrography of Shoulder

Abstract

The glenohumeral joint boasts the greatest range of motion of any peripheral joint in the body, but not without cost; it is also the most frequently dislocated joint in the body. Stability of this articulation is limited for two major reasons. The articulating surface of the glenoid is significantly smaller than that of the humeral head, and the joint capsule is redundant and provides little support. This unit presents a basic MR arthrography protocol for evaluation of glenohumeral joint instability.
