Role of MRI Arthrography In Assessment Of Traumatic Anterior Shoulder Instability

Abstract

Glenohumeral instability remains a very complex and sometimes challenging diagnostic problem. There are potential lesions of the capsule and Labro-ligamentous structures that can occur in association with anterior shoulder instability, and the clinical history and physical findings are not always sufficient to make accurate diagnosis.

In the past, several imaging modalities were used ranging from conventional radiography, arthrography to computerized axial arthrography. Recently, various imaging modalities are now available including ultrasonography, CT arthrography, conventional MRI and MR arthrography.

Conventional MR imaging, had been used in the examination of patients with shoulder instability, though it has been pointed out that accurate interpretation of glenohumeral joint structures is beset with pitfalls.

To improve the evaluation of smaller intra-articular structures such as the glenoid labrum and glenohumeral ligaments, MR arthrography is increasingly recognized as the examination of choice in glenohumeral instability providin
