title: [Ulna impaction syndrome therapy: decompressive surgical procedures of the head of the ulna].
abstract: The ulnar impaction syndrome can be defined as the impaction of the ulnar head against the triangular fibrocartilage complex and ulnar carpus. As a result of this pattern, painful degeneration of the TFCC occurs. Wrist arthroscopy offers a certain diagnostic tool. In addition, arthroscopic debridement of the TFCC shows a high success rate of 70 to 80 percent. After failed arthroscopic debridement, ulnar shortening osteotomy reduces ulnar load significantly. Malunion of the radius resulting in posttraumatic ulna-plus variance should be treated by correction osteotomy with lengthening of the radius. If arthrosis of the distal radioulnar joint is combined with ulnar impaction syndrome, the hemiresection procedure of Bowers or the method of Kapandji-Sauvé are the methods of choice.
