ABSTRACT:
A prosthetic implant for resurfacing a damaged base portion of the proximal phalanx in a human great toe comprises a base fabricated from a titanium, ceramic or other durable and rigid biocompatible material. The base is generally elliptical and includes an anatomically-shaped proximal articular surface having an enlarged build-up on the lateral end thereof. The base also includes a generally planar distal seating surface disposed for engaging the sectioned portion of the proximal phalanx. An elongated stem extends distally from the seating surface of the base and includes an array of fins together having a cruciate-shaped cross section. The fins each include a plurality of serrations along their sloping edges for anchoring the stem within the cancellous portion of the proximal phalanx.
