Basics of Elbow Arthroscopy Part III: Positioning and Diagnostic Arthroscopy in the Lateral Decubitus Position

In recent years, arthroscopy has gained popularity as a preferred treatment of a multitude of pathologies affecting the elbow. Since its initial description in 1985, many modifications have been made as our knowledge and technology have advanced. Currently, the majority of arthroscopic procedures are performed in either the lateral decubitus or supine suspended position. In this work, we discuss the history, patient positioning, and key steps for performing elbow arthroscopy in the lateral decubitus position. In addition to key steps, a number of strengths and limitations of this set up are discussed in detail. When properly executed, elbow arthroscopy can be performed in a safe and efficient manner with minimal risk to patients.
