Patent number: 8911443Abstract: A plate holder is provided to facilitate percutaneous introduction of a bone plate, positioning of the plate on a bone surface, and stabilizing the plate while a fastener is inserted through the plate into the bone. The plate holder includes a proximal handle, a distal mount, and an arm extending between the handle and the mount. The mount includes a first portion which seats within a slot on the shaft of a plate, and a second portion at which the shaft is coupled and which includes a tapered proximal side. A set screw hole is provided through the first and second portions, and a set screw is provided therein. When the first portion is seated in a compression slot of a plate and the set screw is driven to seat, the set screw locks the mount to the plate.Type: GrantFiled: September 14, 2012Date of Patent: December 16, 2014Assignee: Biomet C.V.Inventors: Robert Graham, Cesare Cavallazzi, Marcus Bourda, G. Mark Lindsay, Edward Mebarak, Roy Sanders

Patent number: 8317842Abstract: A distal tibia plating system includes anterolateral and medial plates. The anterolateral plate includes a shaft with both threaded first fastener holes and compression slots along its length. The head includes a first row of four threaded fastener holes arranged transversely to the longitudinal axis, a non-threaded compression screw hole, and a plurality of distal tabs. Each tab includes a ring with a single threaded fastener hole and a bridge that couples the ring to the distal end of the plate. The bridge is configured to bend preferentially in a desired direction and to allow tab removal. The medial plate is a low profile plate including a shaft and a relatively enlarged distal head. Several fasteners can be used with the plates. A plate holder is provided to maneuver the plates subcutaneously.Type: GrantFiled: November 30, 2007Date of Patent: November 27, 2012Assignee: Biomet C.V.Inventors: Robert Graham, Cesare Cavallazzi, Marcus Bourda, G.

Patent number: 8262707Abstract: A periarticular bone plate for the internal fixation of a fractured, proximal tibia of a surgical patient includes a shaft member connected to a head member, a top surface, a bottom surface, a posterior edge, an anterior edge and a plurality of holes extending between the top and bottom surfaces for receiving fasteners for attaching the plate to the bone. The head member is offset relative to the shaft member in each of a frontal and sagittal planes of the proximal tibia.Type: GrantFiled: July 31, 2008Date of Patent: September 11, 2012Assignee: Biomet C.V.Inventors: Dave Huebner, George Haidukewych, G. Mark Lindsay, Craig S. Tsukayama, Roy Sanders

Patent number: 8197405Abstract: A surgical retractor assembly is disclosed that includes a bone plate and a retractor. The bone plate has a tapered end portion. The retractor includes a base having (i) a body defining a bottom surface and a distal portion, the distal portion defining a distal surface, (iii) a first pair of tabs extending from the body that are spaced apart from each other, and (iv) a second pair of tabs extending from the body that are spaced apart from each other. The retractor further includes a handle attached to the base. The first pair of tabs and the bottom surface define a first plate space. The second pair of tabs and the distal surface define a second plate space.Type: GrantFiled: December 3, 2008Date of Patent: June 12, 2012Assignee: DePuy Products, Inc.Inventors: G. Mark Lindsay, Priya R. Prasad, Stephen R. Donnelly

The second pair of tabs and the distal surface define a second plate space. The retractor is positionable in relation to the bone plate between a first position and a second position. When the retractor is positioned in the first position, (i) the bone plate is positioned in the first plate space, and (ii) the bone plate is located outside of the second plate space.Type: ApplicationFiled: December 3, 2008Publication date: June 3, 2010Applicant: DePuy Products, Inc.Inventors: G.
