Comparison of Disadvantages of Shoulder Arthroscopic Surgery in Lateral Decubitus, Beach-Chair, and Modified Semilateral Decubitus Positions

Disadvantages	Lateral Decubitus	Beach Chair	Modified Semilateral Decubitus
Orientation of anatomy	●		●
More difficult for training residents, especially with rotator cuff work	●		●
Usually requires general anesthetic	●
Increased risk of cardiovascular and cerebral hypoperfusion		●
Requires arm-holding sleeve and balanced suspension device	●		●
Less visualization in posterior and inferior aspects of joint		●
Increased risk of neurapraxia to brachial plexus and peripheral nerve	●		●
More difficult to control arm rotation (external and/or internal), making access to some structures more difficult (e.g., subscapularis tears)	●
Potential difficulty with conversion to open procedure	●
