**7.1. Surgical positioning**

Surgery is typically performed in an ambulatory setting, under combination general and regional anesthesia. After induction of anesthesia, and prior to positioning (with the patient supine on the operating table), the shoulder should be examined for passive motion and stability. Manipulation of the shoulder to regain motion should be performed as needed. We prefer a beach-chair position with the arm supported by a hydraulic arm positioner device, but a lateral decubitus with balanced suspension-traction may also be used.
