Patent number: 8556942Abstract: An implantable orthopedic assembly comprises an occipital plate and one or more repositionable clamping assemblies for securing a stabilizing rod to the plate. When unlocked, the clamping assembly may be laterally and rotationally repositioned along a supporting rail. Locking occurs when a stabilizing rod is secured in the clamping assembly.

The bone fixation plate conforms to the contour of an irregularly shaped bone and eliminates the need for pre-bending or intraoperative bending of the plate. The bone plate is applied to the bone in a generally flat condition and the process of installing and tightening the bone screws in the prescribed order serves to contour the plate to the plate to the underlying bone while providing sufficient strength to effect bone healing. The geometry of the plate allows the plate to follow the contour of an irregularly shaped bone, preventing prominence and patient palpability and streamlining the surgical procedure.Type: GrantFiled: April 13, 2009Date of Patent: May 21, 2013Assignee: MBD Medical LLCInventors: James D. Ralph, Thomas N. Troxell, Mark Michels, Thomas D. Meade

Patent number: 8439956Abstract: A method of performing a decompressive craniectomy includes removing a bone flap from a cranium, attaching one end of a movable plate to one end of the bone flap, and attaching another end of the movable plate to the cranium. The movable plate is configured to allow the bone flap to move to accommodate swelling of intracranial contents.Type: GrantFiled: May 17, 2007Date of Patent: May 14, 2013Assignee: Gyrus Productions, Inc.Inventor: Kathryn Ko

Patent number: 8439918Abstract: An improved means for fixation of a fractured coronoid process of the proximal ulna. A substantially rigid plate is secured to the anterior aspect of the proximal ulna relative to a fracture of the coronoid process of the ulna. The plate contains a hook feature at the proximal aspect and is positioned so that it extends over the proximal/anterior aspect of the coronoid process relative to the fracture. The plate has surfaces that define a plurality of openings through which suture and/or screws can pass. The openings may contain a recess at a side of the plate opposite the ulna. At least one hole is formed in the ulna. At least one anchor may be secured to a flexible device, positioned at a side of the plate opposite the ulna, secured to another anchor on the posterior aspect of the ulna and the flexible device tensioned. At least one screw may be inserted through the plate and into the coronoid process or a bone fragment securing it to the plate.Type: GrantFiled: December 1, 2009Date of Patent: May 14, 2013Assignee: Suspension Orthopaedic Solutions, Inc.Inventor: Jeffrey Gelfand

Publication number: 20130116734Abstract: A system for fixing fractured bone portions of a distal humerus in position with respect to one another. In one embodiment, the system includes a plate portion, a projection portion, and a fixation post. The plate portion includes a surface for contacting a posterior portion of the distal humerus adjacent one of a lateral side and a medial side thereof. The projection portion extends outwardly from the plate portion and includes an aperture for receiving the fixation post. The fixation post includes at least one fenestration, and extends from adjacent the one of the lateral and medial sides of the distal humerus to adjacent the other of the lateral and medial sides of the distal humerus.Type: ApplicationFiled: November 9, 2012Publication date: May 9, 2013Inventor: Eduardo Gonzalez-Hernandez

Publication number: 20130096630Abstract: An interlocking bone plate system includes an outer bone plate for being arranged outside a broken bone, an inner bone plate for being installed inside the medullary cavity of the broken bone, and screws for being inserted through and engaged with the outer bone plate and the broken bone and then engaged with the inner bone plate so as to interlock the out and inner bone plates together. The inner bone plate provides an added support in addition to the support provided by the outer bone plate, enhancing the structural strength of the whole bone fixation structure and lowering the risk of failed surgery.Type: ApplicationFiled: March 13, 2012Publication date: April 18, 2013Inventors: Cheng-Hung LEE, Chih-Han Chang, Chih-Kun Hsiao, Kui-Chou Huang, Chih-Hui Chen

Publication number: 20130096631Abstract: An apparatus can include a plate member having a top surface, a bottom surface and a hole extending between the top and bottom surfaces. The plate member hole can have a spherically shaped sidewall. A right-hand helical thread can be formed in the sidewall of the plate member hole, and a left-hand helical cut can be formed in the sidewall of the plate member hole intersecting the right-hand helical thread. The left-hand helical cut can be configured to reduce a portion of a contact surface area of the right-hand helical thread and the sidewall of the plate member hole.Type: ApplicationFiled: October 12, 2012Publication date: April 18, 2013Applicant: BIOMET TRAUMA, LLCInventor: Biomet Trauma, LLC

Publication number: 20130096632Abstract: A fixation device for the fixation of bone fragments, applicable to the mutual fastening of bone fragments temporarily separated during a surgical operation or as a result of a trauma. The device is also suitable for the fixation of a bone flap in the replacement thereof in a corresponding aperture made in the cranium or cranial bone mass. The device is made of biocompatible material and comprises a flexible strip and fastening means, the strip having a length allowing the formation of a fastening loop tightly fastening the bone fragments to be joined together. The fastening means are provided with at least one opening provided with interlocking means allowing the passage of a free end of the strip and preventing its extraction in the direction opposite to the insertion.Type: ApplicationFiled: December 4, 2012Publication date: April 18, 2013Applicant: NEOS SURGERY, S.L.Inventor: NEOS SURGERY, S.L.

Publication number: 20130090694Abstract: A bone plating system comprising: a plate, where the plate is low-profile and capable of contouring to a bone; a variable number of screw holes, locking or non-locking; at least one channel or tunnel through the plate; and at least one flexible device passing through the channel or tunnel and passing through soft tissue attached to the bone. The low profile plate, in combination with the flexible device passing through the surrounding soft tissue, functions as a tension band and acts to neutralize the muscle forces tending to pull the bone apart at a fracture. The low profile tension band plating system is targeted for periarticular tensile fractures for repair of patella, olecranon, greater trochanter, greater tuberosity, radial styloid, lateral or medial malleoli, or lateral malleolus.Type: ApplicationFiled: October 11, 2011Publication date: April 11, 2013Inventors: Brent Lane Norris, Paul Ryan Stafford, Dana James Funk
