Abstract

An artificial joint for implantation in humans and animals, the joint comprising a joint body arranged between two base elements which are adapted to be connected to adjoining bone parts. The two base elements comprise horizontal and vertical retaining members respectively, that hold the joint body between them. The joint body comprises curved surfaces arranged to make sliding contact to corresponding curved surfaces of at least one base element. The joint body this way distributes the applied forces over a large surface to withstand the load initiated by the patient. The joint body is kept in position using pins held by retaining members at the base elements. The angle of motion can be predetermined by the design of the implant body to mimic the movement of a normal finger.
