This document discusses chronic shoulder dislocation and SLAP lesions of the shoulder. It describes the 7 types of SLAP lesions that can occur, involving tears in the superior labrum and detachment of the biceps tendon. Type I involves fraying of the superior labrum while it remains attached. Type II is a separation of the superior labrum and biceps tendon. The document lists the characteristics of types I-VII and concludes with thanking the audience.

27. • A SLAP tear or SLAP lesion is an injury to
the glenoid labrum (fibrocartilaginous rim
attached around the margin of the glenoid
cavity). SLAP is an acronym for "superior
labral tear from anterior to posterior".

28. • Although ten varieties of SLAP lesion have
been described on MRI or MR
arthrography[5] seven clinical types are
generally described.[6]
• Type I. Degenerative fraying of the superior
portion of the labrum, with the labrum
remaining firmly attached to the glenoid rim

29. • Type II. Separation of the superior portion of
the glenoid labrum and tendon of the biceps
brachii muscle from the glenoid rim
• Type III. Bucket-handle tears of the superior
portion of the labrum without involvement of
the biceps brachii (long head) attachment

30. • Type IV. Bucket-handle tears of the superior
portion of the labrum extending into the
biceps tendon
• Type V. Anteroinferior Bankart lesion that
extends upward to include a separation of the
biceps tendon

31. • Type VI. Unstable radial flap tears associated
with separation of the biceps anchor
• Type VII. Anterior extension of the SLAP lesion
beneath the middle glenohumeral ligament
