Patent number: 8888857Abstract: A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available. The meniscal component includes a mechanism for preventing lift off of the meniscal component from the tibial component, while allowing rotation of the meniscal component relative to the tibial component.Type: GrantFiled: September 5, 2012Date of Patent: November 18, 2014Assignee: Zimmer, Inc.Inventors: John E. Meyers, George D. Letson, Russell Windsor, Vincent A. Webster, Bill N. Sisk, Bill H. Haywood, Adam M. Griner, Michael Cook, Rodney L. Bays, Jerry L. Aikins, Marvin Figueroa, Peter S. Walker

Patent number: 7316687Abstract: A blade plate, as well as instruments and methods for securing the blade plate to a bone to reduce a bone fracture. The blade plate includes a plate portion and a blade portion extending at an angle relative to the plate portion. The plate portion includes a plurality of holes for receipt of bone screws for securing the blade plate to the bone about the bone fracture. A strut screw, inserted through a hole in the plate portion, spans the angle between the plate and blade portions, and threadingly engages a hole in the blade portion to slightly draw the plate and blade portions together to compress and support the bone fracture. A pair of top screws are inserted through holes in the plate portion at angles with respect to the strut screw on either side of the strut screw. Additionally, the blade plate is designed to closely conform to the surface of the bone to minimize the gap between the bone and the blade plate.Type: GrantFiled: August 24, 2001Date of Patent: January 8, 2008Assignee: Zimmer Technology, Inc.Inventors: Jerry L. Aikins, George Brian Cornwall, Raymond Desjardins, Paul Duwelius, James Goulet, David Templeman, John E. Meyers, Scott A. Moon, Gregory G. Price, Patrick Rousseau, Roy Wiley, Robert A. Winquist

Patent number: 5613970Abstract: The invention is directed to an orthopaedic instrumentation assembly 10 located relative to an intramedullary member 12, wherein the intramedullary member is disposed at least partially within a bone. The instrumentation assembly 10 includes an offset bushing 16 having a longitudinal axis and a bore therethrough for receiving the intramedullary member. The bore is disposed non-coaxially relative to the longitudinal axis. A sizing plate 14 has an opening 22 therein, and further includes a portion associated with the opening for receiving the bushing, wherein the bushing is rotatably supported. Upon movement of the bushing 16 or sizing plate 14, the bushing and sizing plate coact to position the sizing plate relative to each of the intramedullary member and the bone.Type: GrantFiled: July 6, 1995Date of Patent: March 25, 1997Assignee: Zimmer, Inc.Inventors: Michelle L.
