Patent number: 11419647Abstract: The present invention is directed to a bone plate and its method of use for reducing a bone fracture, the bone plate having a longitudinal axis, the bone plate comprising an upper surface, a lower surface, a first hole for engaging a head of a first bone anchor. The first hole is configured and adapted to fix a shaft of the first bone anchor along a first axis. A second hole is spaced apart from the first hole along the longitudinal axis. The second hole is for engaging a head of a second bone anchor, and is configured and adapted to fix a shaft of the second bone anchor along a second axis. The first hole and the second hole are configured such that the first axis and the second axis define a single plane and intersect at a point below the lower surface. The shafts of the first and second bone anchors may touch or nearly touch at the point of intersection, such that the first and second bone anchors form a truss.Type: GrantFiled: April 17, 2020Date of Patent: August 23, 2022Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Mark P. Grady, Jr., Rene Haag, Scott Didomenico, Kenny Koay, Jeffrey W. Mast, Brett R. Bolhofner, Keith A. Mayo

Patent number: 9351773Abstract: A tool is disclosed for use in distracting and compressing fractures of any of a variety of bones. In particular, the tool has a pair of engaging arms, one arm having a hook element to engage a bone plate connected to one side of a fracture, and the other arm having at least one recess for engaging a head of a bone screw or guide wire connected to the other side of the fracture. Actuation of the tool causes the opposing bone segments of the fracture to be pushed apart or drawn together, depending on whether the tool handles are squeezed together or pulled apart. The tool may have a scissors joint that allows the ends of the tool to maintain a parallel alignment during operation, thus reducing the chances for misalignment of the bone segments during operation.Type: GrantFiled: May 7, 2014Date of Patent: May 31, 2016Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Scott R. DiDomenico, Jason S. Chan, Jeff W. Mast, Keith A. Mayo, Brett B. Bolhofner

Publication number: 20160074081Abstract: The present invention relates to a bone plating system and method for fracture fixation of bone. The bone plating system includes a bone plate, at least one locking screw, and at least one non-locking screw. The bone plate has locking holes with threads and non-locking holes. The locking screws have a shaft with a thread for engaging bone and a head with a thread configured and dimensioned to mate with the thread of the locking holes. The non-locking screws have a thread for engaging bone and a non-threaded head. Both the locking and non-locking screws remain seated in their respective holes for substantially as long as the bone plate is implanted. The non-locking screws compress the bone plate against the bone and hold fracture reduction while the locking screws are secured to the plate at a fixed angular relationship. The mixed fixation achieved by this bone plating system and method is particularly useful for treatment of per-articular fractures.Type: ApplicationFiled: November 23, 2015Publication date: March 17, 2016Inventors: Paul Weaver, Jeff W.

Patent number: 9011457Abstract: An aiming guide aligns a surgical tool with a hole in a bone plate. The aiming guide includes an arm portion having a longitudinal axis, top and bottom surfaces, and first and second ends. The aiming guide further includes a handle portion having upper and lower ends. The handle portion is, at its lower end, connected to the bone plate. The handle portion is, at its upper end, connected to the arm portion. Bores extend from the top surface to the lower surface of the arm portion. Each bore is configured and dimensioned to receive a tool guide in at least two different preset positions which locates the channel in at least two different hole positions. The bore includes two diametrically opposed slots extending along at least a portion of a length of the bore, the slots configured and dimensioned to mate with diametrically opposed knobs extending radially outward from a tool guide. The tool guide has a head and a sleeve portion, which has a centered channel.Type: GrantFiled: February 5, 2010Date of Patent: April 21, 2015Assignee: DePuy Synthes Products, Inc.Inventors: Mark P.
