Abstract
A metallic implantable finger joint has a biocompatible protective coating and includes both a base member and a protraction member. The base member is formed with a recess and has a protrusion projecting from inside the recess. The protraction member has a hemispherical surface which is slidingly engageable with the recess of the base member. Additionally, the protraction member is formed with a groove which engagingly receives the protrusion from the base member. This engagement is such that when the base member is juxtaposed with the protraction member, the interaction between the protrusion and the groove allows for relative movement between the members in flexion-extension, lateral rotation and pure rotation. The finger joint can also include implant barbs which are selectively engageable with the base member and the protraction member.
