[Arthroscopic treatment of osteoarthritis of scaphotrapezotrapezoid joint.]
Osteoarthritis of scaphotrapezotrapezoïd joint corresponds to 13% of wrist arthritis. It is seldom isolated. The arthroscopic treatment associates a radial mid carpal portal and a STT portal called 1-2 midcarpal portal. Between 2002 and 2005, we carried out 13 resection isolated from the distal pole of the scaphoïd. There were only women whose average age was 58 years. The improvement was real on the level of the pain, mobility and the muscular force. In same time, we operated on 13 patients by associating an implant in pyrocarbone as interposition after resection. The average age was 67 years. The average follow-up was 20 months. We had two implant dislocations for technical errors. The quality of the results helped by the invasive initially mini-approach and the arthroscopy can make it possible to select some indications.
