[The Roseland prosthesis].

Total joint replacement of the trapezio-metacarpal (TMC) joint is one of the procedures available for the surgical treatment of degenerative osteoarthritis or rheumatoid arthritis of the first carpometacarpal joint. A four French Alpine surgeon group, (C. Lebrun, P. Massart, F. Moutet and C. Sartorius) have developed a new cementless total TMC joint prosthesis: the Roseland prosthesis. Such a device tries to improve the biomechanical conditions of the La Caffinière's implant, which was introduced in 1973. Clinical data of a 24 patients with a 38 month mean follow-up series are reported.
