Shoulder Arthroscopy (Cadaver)

1. Landmarks

• Draw out bony landmarks: acromion, coracoid, soft spot.
• Use thumbnail to delineate anterolateral and posterolateral acromion.

2. Posterior Portal

• 2 cm inferior and slightly medial to acromial angle in the “soft spot” between infraspinatus and teres minor.
• Aiming toward coracoid, pierce skin with an 18-gauge needle.
• Insufflate joint with 50 cc of saline/epi solution.
• Make an incision with #11 blade.
• Place a blunt trocar through through capsule.
• Attach inflow to arthroscopic cannula, suction as well.

3. Arthroscopy (Beach Chair Position)

1. Examine Glenoid, Biceps, Humeral Head, Subscapularis, and Rotator Interval.
2. Visualize the RTC and Check the Bare Area, Labrum, and HAGL
3. Create Instrument Portal Through Rotator Interval
4. Test Biceps Tendon
5. Enter Subacromial Space

4. CA Ligament Release

• While in the subacromial space, release the CA ligament off the bone with a radiofrequency ablator.
