Abstract
Arthroscopic shoulder surgery can be performed in both the beach chair and lateral decubitus positions. The lateral decubitus position allows for excellent exposure to all aspects of the glenohumeral joint and is therefore frequently employed in procedures such as stabilization, in which extensive visualization of the inferior and posterior aspects of the joint is required. Improved visualization is imparted due to applied lateral and axial traction on the operative arm, which increases the glenohumeral joint space. To perform arthroscopy surgery in the lateral decubitus position successfully, meticulous care during patient positioning and setup must be taken. In this Technical Note, we describe the steps required to safely, efficiently, and reproducibly perform arthroscopic shoulder surgery in the lateral decubitus position.
