Between 2008 and 2010, an arthroscopic wafer procedure was performed in 24 patients. The resection of the ulnar head was 2.5 mm on average. After a mean follow-up time of 13.25 months, very good results were archived in 23 of 24 patients; the ulnar impingement test was negative. On a visual analog scale (0-10) average postoperative pain was 1.16 at rest and 4.5 under stress. The mean postoperative DASH score was 13.4.
