Abstract: The present disclosure provides a joint implant for replacing a finger joint. The joint implant includes a first component, wherein the first component includes a first joint section and a first anchoring section, the first joint section including a concave joint surface about a first axis and the first anchoring section extending transverse to the first axis. The joint implant also includes a second component, wherein the second component includes a second joint section and a second anchoring section, the second joint section including a circumferential surface about a second axis and the second anchoring section extending transverse to the second axis, wherein the circumferential surface includes a convex joint surface that is configured to act as a hinge joint with the concave joint surface of the first joint section.

Abstract: The invention relates to an arthrodesis plate for the stiffening of joints, in particular finger joints, comprising a proximal and distal anchoring region which are connected to one another in a mechanically rigid manner, characterised in that at least one outer contour of one of the two anchoring regions has a cross-section which is undulating, for example roof-shaped, or is provided with alternating crests and troughs by means of coating, and/or has a transversal-sagittal cross-section.
