| abstract |
According to the state of the art, the replacement of a basal finger joint is effected by, for example, interposition of soft part tissue or a distance piece, which does not, however, constitute a replacement joint. In joint prostheses with a metal-metal sliding combination, but in particular with a metal/polyethylene sliding combination, wear of the material can lead to osteolyses at the bone ends. Owing to the tact that the metal or plastic joint prostheses known from the state of the art are as a rule multipart, loosening of the individual components can occur, which shortens the service life of the implant. n According to the invention, it is therefore proposed that the implant ( 1 ) is an uncoupled, two-part implant. |
