STRUCTURES FOR USE IN ORTHOPAEDIC IMPLANT FIXATION

摘要

An orthopaedic implant including a base portion and first and second transverse portions extending transversely from the base portion to thereby define an inner region of the implant sized for receipt of an end portion of a bone therein. The implant further includes at least one anchor structure projecting from the base portion and sized and configured for receipt within an opening formed in the end portion of the bone. The anchor structure extends along a longitudinal axis and includes a proximal end attached to the base portion and an opposite distal end, and further includes a tapered outer surface that inwardly tapers in a proximal-to-distal direction along the longitudinal axis. In one embodiment, the anchor structure also includes one or more grooves extending into the tapered outer surface, with a flowable material positioned about at least a portion of the tapered outer surface and positioned within the grooves, and with the flowable material configured to cure to a hardened state.
