Patent number: 7846189Abstract: An orthopaedic bone plate is coupled to a bone having an enlarged head at one end thereof which is attached to a shaft. The bone plate includes an elongate portion, a flared portion and an intermediate portion. The elongate portion is attachable to the bone shaft using a plurality of bone screws. The elongate portion generally defines a longitudinal axis. The flared portion is attachable to the bone head using at least one bone screw. The intermediate portion interconnects the elongate portion and the flared portion. The intermediate portion is structured and arranged to allow the elongate portion and the flared portion to move relative to each other in a direction transverse to the longitudinal axis when the elongate portion and the flared portion are attached to the bone.Type: GrantFiled: December 17, 2003Date of Patent: December 7, 2010Assignee: Zimmer, Inc.Inventors: Robert A Winquist, Steve Benirschke, Paul Duwelius, Raymond Desjardins, David Templeman, John E Meyers, Stanley W Patterson, Gregory G Price, James Goulet

Publication number: 20080027458Abstract: 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: ApplicationFiled: October 8, 2007Publication date: January 31, 2008Applicant: ZIMMER TECHNOLOGY, INC.Inventors: Jerry Aikins, George Cornwall, Raymond Desjardins, Paul Duwelius, James Goulet, David Templeman, John Meyers, Scott Moon, Gregory Price, Patrick Rousseau, Roy Wiley, Robert Winquist
