The Role of CT Arthrography in Shoulder Instability

Computerized Tomography (CT) and CT arthrography are useful tools in evaluating both the osseous structures and the soft tissues in patients with shoulder instability. A variety of osseous injuries can be accurately depicted, such as Hill-Sachs lesions, glenoid rim fractures, or glenoid bone loss. CT arthrography further allows precise evaluations of labral and chondral defects. Further, CT is a simple modality for performing anatomical measurements in the shoulder such as glenoid version or for the assessment of osseous deficiencies of the posterior glenoid. Finally, CT is also be beneficial for assessing patients in the postoperative situation.
