[Arthroscopy of the wrist].

Wrist arthroscopy may add specific datas to that provided by standard or motion view radiographs, arthrography, bone scan, TDM or RMN. Eight portals allow direct visualization of articular surfaces of radio-carpal and medio-carpal joints, triangular fibrocartilage, spaces between the carpal bones, interosseous and extrinsic ligaments. Wrist arthroscopy may be useful to evaluate lesions involving ligaments or cartilages, in degenerative or post-traumatic conditions. Arthroscopy may help to the decision in treatment of carpal instabilities, scaphoid pseudarthrosis, or Kienbock disease. Operative arthroscopy may allow shaving of damaged cartilage or fibrocartilage, bone resection or triangular fibrocartilage reinsertion.
