Abstract

A bone resection tool for resecting an end of a bone along a surface having a curvature comprises a guide, a cutting tool and a track follower. The guide is configured to be removably attached in a fixed position to the end of the bone. The guide is configured to include a track exhibiting a curvature generally corresponding to the curvature of the surface to be resected in the bone. The cutting tool includes a cutting face. The track follower is configured to couple to the cutting tool and cooperate with the track to facilitate reciprocation of the cutting tool relative to the guide to induce the cutting face to resect the bone along the surface having the curvature. A method for cutting a bone along a curved surface conforming to the curvature of a curved surface of the underside of a prosthetic component comprises the steps of incising the tissue surrounding the surface of the bone, positioning a guide alongside the surface of a bone to be cut, affixing the guide to the bone, interconnecting a cutter having a cutting face with the guide, maintaining the cutting face generally parallel to the tangent of the curved surface and traversing the cutting face along the bone while guidi…
