Current Concepts Imaging Techniques for the Evaluation of Glenohumeral Instability

The ability to image lesions associated with glenohu-meral instability has evolved significantly over the past 2 decades. In the past, several imaging techniques ranging from conventional radiography to computer-ized axial arthrography and, most recently, to magnetic resonance imaging have been used to depict various labral abnormalities. In most instances, conventional radiography remains the initial imaging study for eval-uating the patient with persistent shoulder pain and instability. Recently, however, magnetic resonance ar-thrography has been firmly established as the imaging modality of choice for demonstrating specific soft tis-sue abnormalities associated with glenohumeral insta-bility. This article will review the role of various imagin
