We reported a retrospective study of 36 patients with a pseudoarthrosis of thecarpal scaphoid bone treated by the Matti-Russe operation from 1985 to 1991. We used radial(50%), iliac (42%) or ulnar (8%) autogenous grafts without any difference in the rate of incorporation.The rate of healing of the pseudoarthrosis was higher in mid and distal location(80%) than in proximal location (54%). In 80% of cases, healing failures in the mid and distallocation occurred in old pseudoarthrosis ( > 3 0 months evolution). Carpal degenerative changeswere significantly higher ( p < 0,01) in patients with not healed pseudoarthrosis. The locationand the age of the pseudoarthrosis appear to be important prognostic factors. The Matti-Russetechnique has limitations when is performed either in proximal pseudoarthrosis or in the presenceof advanced radiocarpal osteoarthritis.
