- Discussion:
- w/ arm in external rotation, upper & lower borders of subscapularis can be visualized and palpated;
- rotator cuff interval (soft spot) between supraspinatus & subscapularis is identified;
- subscapularis tendon is tagged just shy of insertion;
- subscapularis tendon and subajacent capsule are separated w/ cautery;
- inferior dissection will encounter AHCA and axillary nerve;
- greater exposure is obtained by dividing coracohumeral ligament which is located just medial to intra-articular Biceps tendon;
- nerves to the rotator cuff muscles lie on their deep surface, & medial dissection on the deep muscles may jeopardize their nerve supply;
- small (< 1 cm) defect is normally found in the capsule just below coracoid process, the articular opening of the subcoracoid recess;
- labram may remain attached to capsular ligaments, or may remain on glenoid side of rupture;
- this should not be confused with a Bankart Lesion
