Improved visualization of the glenohumeral joint, obviating the need to create accessory portals that disrupt the rotator cuff |
Risk of neurologic injury due to applied lateral and axial traction on the operative arm (peripheral nerves and brachial plexus) |
Increased working space, specifically to the inferior and posterior labrum, inferior capsule, subacromial space, and articular side of the rotator cuff |
Risk of vascular injury due to portal placement, especially the cephalic vein |
Allows surgeon to operate with arms at side for increased comfort and decreased fatigue (as opposed to abducted position) |
Increased difficulty with intraoperative conversion to an open approach |
Bubbles created by electrocautery move laterally, providing a clearer view |
Difficulty manipulating the operative arm when in applied traction |
Lower incidence of cerebral desaturation events compared with the beach chair position. |
Increased difficulty identifying internal and external anatomic landmarks |
