Publication number: 20050171545Abstract: A bone cutting guide block has a saw guide surface thereon and has a body shaped to conform to the anterior-medial shape of the proximal left tibia and distal left femur and also to the anterior-lateral shape of the proximal right tibia or the distal right femur. The block is used by placing the curved inner surface adjacent the anterior-medial or anterior-lateral quadrant of either the tibia or the femur and utilizing images from a computer database utilizing an optical tracking system mounted on the cutting block and referencing to the bone to be cut. Utilizing the tracking system, the cutting guide is positioned preferably by hand in the proximal-distal direction to set the depth of the resection. The cutting guide surface is then oriented by hand to the correct varus-valgus and/or flexion-extension angles and pinned to the bone.Type: ApplicationFiled: January 30, 2004Publication date: August 4, 2005Applicant: Howmedica Osteonics Corp.Inventors: Gearoid Walsh, Sandeep Chauhan
