Zusammenfassung:	PCT No. PCT/FR92/00845 Sec. 371 Date Apr. 26, 1994 Sec. 102(e) Date Apr. 26, 1994 PCT Filed Sep. 6, 1991 PCT Pub. No. WO93/04644 PCT Pub. Date Mar. 18, 1993.A finger joint prosthesis for metacarpalphalangeal and interphalangeal joints is provided including two diaphyseal parts which are implantable in the phalangeal and/or metacarpal bones and are fixed to a pivotable joint. The joint includes a female cap, a male cap, a shaft force fitted into two openings in the female cap and extending through an opening in the male cap, and a collar surrounding the shaft in the male cap. The joint also includes two side flanges which hold disks for holding the collar in place. The female and male caps and the side flanges are made of titanium alloy while the collar, the shaft, and the disks are made of pyrocarbon so that friction during rotation of the joint occurs only between components that are made of pyrocarbon.
