A joint resurfacing prosthetic implant system is disclosed having an anatomically-shaped implant to replace a joint at a pedal digit or finger, including a head having an elliptical bearing surface disposed for engaging the end of an adjacent bone and a seating surface opposite the bearing surface, an elongated stem extending distally from the seating surface, and a flange on the circumference of the device and extending distally from the seating surface. The flange includes one or more portals and a removed section configured to avoid impinging upon a tendon during and after implantation of the prosthetic. A specialized tool is also provided to facilitate the resection of the bone for implantation. The specialized tool includes an elliptical template having a cutting edge and a center insert that is sized and configured to match a reamer used to bore into the bone for insertion of the implant.
