Patent ID: 8372154

Claim:
A modular prosthesis for placement in a wrist relative to a radius and a carpal bone, comprising: a carpal bearing component including: a wrist bearing component; a carpal implant extending between a carpal complex engaging side and a proximal side, said carpal implant having an integral scaphoid replacement section having a greater thickness relative to a remainder of said carpal implant, said integral scaphoid replacement section configured to interface with a trapezoid and a trapezium; a modular distal radial assembly including: a stem member operable to be positioned relative to a portion of the radius; a distal radial bone replacement member operable to be interconnected with said stem member during an operative procedure; an interconnection device provided on each of the stem member and the distal radial bone replacement member that is operable to fasten the stem member to the distal radial bone replacement member; and an articulation member connected to the distal radial bone replacement member and operable to articulate with the carpal implant to substantially mimic a natural articulation of the wrist, the articulation member includes an articulating region that includes at least one of a prosthesis articulating region and a bony portion articulating region, the articulating region includes a containing portion including a wall operable to surround the wrist bearing component; wherein said stem member and said distal radial bone replacement member are provided to be interconnected to substantially form a portion of a radial articulation with the carpal bearing component.
