SLAP lesion involves injury to which structure?

SLAP lesion involves injury to which structure?

• A. Infraspinatus tendon
• B. Superior Labrum of the glenoid
• C. Acromioclavicular joint
• D. Coracoid process

Answer: (B)

A SLAP lesion involves injury to the superior labrum of the glenoid. This structure is the fibrocartilaginous rim around the top of the shoulder socket that deepens the glenoid and serves as the anchor for the long head of the biceps tendon. When the superior labrum tears, it disrupts this biceps attachment and the rim’s stability, leading to pain, catching, and instability with shoulder motion. The other options refer to different structures: the infraspinatus tendon is part of the rotator cuff, the acromioclavicular joint is a separate joint at the top of the shoulder, and the coracoid process is a bony projection—none of which define a SLAP lesion.
