Abstract

In accordance with the present invention, an instrument for surgically implanting a grommet for a flexible small bone joint replacement prostheses, such as a finger joint, is provided. The instrument includes a handle having a central axis with opposed proximal and distal ends, wherein the distal end of the handle is configured with a first connection portion. A head having opposed proximal and distal portions includes a base extending axially from the distal portion, the proximal portion of the head being configured with a second connection portion for releasable engagement with the first connection portion of the handle. A post protrudes distally from the base and includes a cross section which is tapered in a distal direction from a thicker portion at the intersection of the post with the base toward the tip of the post. The taper of the stem portion is adapted for mating with the grommet to be implanted into the medullary canal of bone.
