title: [Arthroplasty of the metacarpophalangeal joint using pyrocarbonate implants].
abstract: As early as the 1970s, pyrocarbon became a point of focus in the search for materials for alternative finger replacement. This type of material had already proven its biocompatibility and excellent wear behaviour in its use for artificial heart valves. The first trials with pyrocarbon surface replacement implants for the small finger joints in baboons showed good biocompatibility as well as good functional results. The first patient series confirmed theses results in long-term follow-up. Meanwhile, the surface replacement implants made of pyrocarbon are an interesting alternative to silicon spacers. Further developments for other joints in the hand are under evaluation.
