Glenolabral articular disruption lesions
Glenolabral articular disruption (GLAD) lesions result from a forced adduction injury. There is a superficial anterior inferior labral tear associated with an anterior inferior glenoid articular cartilage injury. These lesions do not tend to be associated with shoulder instability.
It is better visualised in ABER position. Articular cartilage lesions are best demonstrated with MR arthrography.
Images demonstrate a non-displaced tear involving the superficial anteroinferior labrum with associated injury to the adjacent cartilage 4.
The anterior labrum and glenoid articular cartilage often demonstrate normal morphology one image superior to the GLAD lesion.
Treatment and prognosis
Treatment options include glenoid articular chondroplasty or an abrasion arthroplasty. Recovery usually takes about three months.
