Shoulder arthroscopy is most commonly performed in some variation of the lateral decubitus position with the arm in traction. Because of reports of neuropraxia associated with the traction, we have investigated the use of the "beachchair" or sitting position for shoulder arthroscopy. We have used this position for over 50 consecutive patients for arthroscopic debridements, arthroscopic subacromial decompressions, and arthroscopic shoulder stabilizations.
