    摘要: 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 guiding the cutter along the track. The tissue incision incises the tissue surrounding the surface of the bone to be cut in a minimally invasive fashion. The positioned guide includes a track configured to assimilate the curvature of the curved surface of the underside of the prosthetic component.

    摘要: A surgical instrument for use in an orthopaedic arthroplasty procedure includes a shaft having a first end and a second end and an impactor head disposed at the second end of the shaft. The impactor head includes first and second spaced ends, two spaced impaction surfaces disposed at the second end, and a cavity disposed between the impaction surfaces. The cavity is adapted to accommodate posterior-stabilizing spines of at least a first tibial implant component and a second tibial implant component having a size different than a size of the first tibial implant component. Each of the impaction surfaces includes a first section with a contour that conforms to a contour of a bearing surface of the first tibial implant component and a second section with a contour that conforms to a contour of a bearing surface of the second tibial implant component.

    摘要: A posterior stabilized knee orthopaedic prosthesis assembly includes a tibial bearing, a primary femoral component, and a revision femoral component. Each of the primary and revision femoral components is configured to separately articulate with the tibial bearing. However, each of the primary and revision femoral components has different geometry. The primary femoral component includes a posterior cam having a posterior cam surfacing including a concave cam surface and a convex cam surface. The revision femoral component includes a posterior cam having only a convex cam surface.
