Publication number: 20100094300Abstract: The present invention comprises a set of instruments and a method for their use in preparing a knee joint to receive knee implants. The inventive instruments and method are generally suitable for knee joint surgery. Furthermore, they include features that make them suitable for performing a minimally invasive knee surgery in which a smaller than normal incision is made and oriented to preserve the quadriceps mechanism and protect the suprapatellar pouch. The instruments permit switching from a minimally invasive technique to a standard open technique at any point in the procedure. An illustrative set of instruments for total knee arthroplasty and an associated minimally invasive technique are described.Type: ApplicationFiled: December 15, 2009Publication date: April 15, 2010Applicant: ZIMMER, INC.Inventors: Thomas M. Coon, E. Marlowe Goble, Alfred J. Tria, JR., Warren Scott Gareiss, Robert A. Hodorek, Toby N. Farling, Daniel F. Justin, Donald M. Smucker, Richard R. Van Zile

Patent number: 7285122Abstract: A method of resecting a proximal tibia and distal femur for implanting a partial knee prosthesis uses a resecting kit which includes multiple spacers, each of which has a different spacing dimension. A surgeon selects the appropriate spacer with the amount of correction desired to align the patient's leg and installs the spacer with the spacing dimension between the distal femur and proximal tibia which is to receive the partial knee prosthesis. The spacers have projecting stems, upon which a resector is installed. The resector is then aligned with the axis selected by the surgeon according to known methods, and is pinned to the femur and proximal tibia. A distal femoral cut is then made in the femur after which the resector is removed while leaving at least two of the pins in place, the pins being headless pins. A second resector is then installed on the pins to effect the required cut of the tibia.Type: GrantFiled: June 16, 2003Date of Patent: October 23, 2007Assignee: Zimmer, Inc.Inventors: Adam H. Sanford, Toby N. Farling, Robert A. Hodorek, Mark A. Price, Paul L. Saenger, Richard V. Williamson

Publication number: 20070239153Abstract: A method and apparatus for a computer assisted surgery (CAS) system using alternative energy tissue and bone alteration technology. The CAS system utilizes alternative energy technology which is a directed to a surgical instrument including an alteration or cutting tip. The tip may be in contact with the tissue or bone, or, alternatively, the tip may be distant from the tissue or bone and the energy is projected to the desired cut or alteration site. The CAS system recognizes the location of the tip relative to a desired alteration location or area and de-energizes or varies the energy level when the tip moves away from or out of the predetermined alteration location or path. The CAS system provides a method for altering or resecting bone, for example, in preparation for a prosthetic implant, or a method for altering tissue, for example, cauterizing blood vessels or bonding ligaments to bones.Type: ApplicationFiled: February 22, 2006Publication date: October 11, 2007Inventors: Robert Hodorek, Donald Patmore
