Claims4
A modular implant for replacing the head of the proximal end of a radius and for articulating with the capitellum of a humerus, said implant comprising:
- (a) a modular head including a proximal end having a concavity therein for articulating with the capitellum of the humerus, and including a first lock member;
- and
- (b) a modular body including distal end for connecting to the radius, including a second lock member for coacting with said first lock member of said modular head to lock said modular head and said modular body together, and having a drainage passage allowing fluid trapped between said first and second lock members to drain out.
