ABSTRACT
Superior labral anterior to posterior (SLAP) lesions describe injuries to the superior labrum (1) and are classified into four basic types. Type I lesions consist of fraying and degeneration (Fig. 1), type II consists of detachment of the biceps anchor (Fig. 2), type III lesions consist of a bucket-handle tear (Fig. 3), and type IV lesions are similar to a type III lesion with extension of the tear into the biceps tendon (Fig. 4). Combinations of these lesions may also be observed.
