- refers to a detachment lesion of the superior aspect of glenoid labrum, which serves as the insertion of long head of biceps;

- varient anatomy:
- in 50% of patients, biceps predominately attaches to supraglenoid tubercle where as in other half biceps predominately attaches to superior labrum;
- slight detachment of the superior posterior labrum may be normal in older aults;
- Buford complex: (see shoulder capsule)
- anatomical variant: MGHL ligament appears cord-like and will often be frayed and is often associated w/ a physiologic antero-superior sublabral hole;
- glenoid labrum opposite of the MGHL will often be absent;
- attempts to close down this sub-labral hole w/ a absorable tack anchor may precipitate frozen shoulder;
- in most cases a SLAP lesion will show infammatory changes around the biceps tendon origin;
- arthroscopic findings: (true slap vs normal findings)
- glenoid chondromalacia in the area of detachment, with corresponding fraying on the underside of the detached labrum and glenoid;
- anterior cannula may be used to hold labrum against the glenoid while the shoulder is externally rotated;
- normal variants will pop free with external rotation, while tears can be held inplace;

- Treatment of Labral Tears with Associated Spinoglenoid Cysts without Cyst Decompression
- labral exposure:
- consider passing a heavy suture under the labrum and bringing both ends of the suture out of the end of the canula;
- tension is kept constant by applying a clamp over the sutures at the end of the canula.
- this will keep the labram out of the way while drilling and suture passage is completed.
- once the labrum is ready to be secured, tension on the stay suture is released;
- anchor position:
- goal is insertion within the superior glenoid tubercle;
- consider hand tamping the drill bit instead of power drilling, so that the drill bit will not skive;
