Patent number: 10893947Abstract: A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.Type: GrantFiled: September 5, 2018Date of Patent: January 19, 2021Assignee: Zimmer, Inc.Inventors: Jeff Blaylock, Michael Cook, Ron Donkers, Scott Dykema, Maleata Hall, John E.

Publication number: 20050215888Abstract: A universal tracking apparatus for a surgical instrument, the tracking apparatus including a support arm and tracking array. The support arm allows position adjustment of the tracking array between a number of predefined orientations relative to the instrument which are recognizeable and registerable in the navigation system. The support arm may be coupled with multiple types of surgical instruments and used to accurately define the position of the instrument in an anatomical model generated by the navigation system. The adjustable coupling between the tracking array and the support arm allows the surgeon to determine which orientation is best suited for the surgical application and also allows the surgeon to adjust the position of the tracking array during a surgical procedure without the need to re-register the tracking apparatus.Type: ApplicationFiled: February 14, 2005Publication date: September 29, 2005Inventors: James Grimm, Shawn McGinley, Jacque Wilson, Maleata Hall, Dale Walriven, Sudip Hui, Chetan Rangaiah
