hallmark is the pathologic detachment of the labrum and biceps anchor from the superior glenoid

54
Q

describe a type III SLAP lesion

superior labrum ha a vertical tear analogous to a bucket handle tear in the meniscus of the knee

the remaining rim of the labral tissue is well anchored to the glenoid, and the biceps anchor is intact

vertical tear of the superior labrum, but this superior labral tear extends to a variable extent up into the biceps tendon as well
