We evaluated the use of the beach-chair, or sitting, position for arthroscopic shoulder surgery in 50 consecutive patients. Routine arthroscopy, arthroscopic subacromial decompression, and arthroscopic shoulder stabilizations were performed, with no complications. The advantages of this position include ease of setup, lack of brachial plexus strain because no traction is used, excellent intraarticular visualization for all types of arthroscopic shoulder procedures, and ease of conversion to the open approach if needed. The positioning technique is described.

Reflex sympathetic dystrophy (RSD) of the knee is an extremely difficult problem to treat. This study examined the possible relationship between isolated injury to the infrapatellar branch of the saphenous nerve (IPBSN) and the etiology and natural course of RSD. Thirty-five patients with clinically significant sympathetic dystrophy of the knee were examined retrospectively. ⋯ Initial ICSTs of improved and unimproved patients were compared. Baseline temperatures were significantly warmer in patients who improved with therapy (p less than 0.05), and a warmer trend was evident throughout all phases of the test in those who improved compared with those who did not. Eighty percent of patients treated within 1 year improved with one or more vasoactive therapies, whereas only 44 percent improved when treatment was started after 1 year, indicating a significant population difference (p less than 0.05).
