Publication number: 20070270849Abstract: A bone plate for internal fixation of a bone fracture includes top and bottom surfaces and an edge. At least one multifunctional hole is provided along the edge and communicates between the top and bottom surfaces and the edge. The hole generally includes a cylindrical portion for closely receiving and guiding a K-wire in a fixed angle. The hole also includes a lateral channel formed into the bottom surface and the edge of the plate such that a curved suture needle and attached suture material may be passed through the hole even when the plate is fixed to the bone. The multifunctional holes may be arranged along the edges of the plate to maintain or modify the stiffness of the plate.Type: ApplicationFiled: April 21, 2006Publication date: November 22, 2007Inventors: Jorge Orbay, Cesare Cavallazzi, Edward Mebarak, Christopher Bremer

Publication number: 20070191855Abstract: A fracture fixation device includes a plate portion and an intramedullary nail portion which is offset relative to the plate portion by a neck portion. The plate portion includes longitudinally displaced peg holes which orient pegs along an imaginary surface parallel to subchondral bone of an articular surface. The upper surface of the plate portion includes a dimple to reference a jig. The nail portion includes threaded screw holes oriented normal to an endosteal surface, and a smaller K-wire alignment hole parallel to the screw holes. The jig has a first portion which references with the dimple and a second portion in alignment over the screw holes of the nail portion. The back of the first portion of the jig is curved upward to facilitate maneuvering of the jig. The first and second portions of the jig includes K-wire guide holes which direct K-wires relative to holes in the device.Type: ApplicationFiled: January 27, 2006Publication date: August 16, 2007Inventors: Jorge Orbay, Javier Castaneda, Edward Mebarak

Publication number: 20070118125Abstract: The system includes a plate with a screw hole and a bone screw wherein the screw and plate cooperate such that the screw is inhibited from back out from the plate after inserted into bone. Described embodiments include a pawl, with and without ratchet, an interfering clip about the screw head, and a snap-fit engagement between the screw and screw hole. The screw hole is preferably provided with openings at at least one of two diametric sides which provide dynamic compression functionality and access under the screw for an instrument to facilitate screw release.Type: ApplicationFiled: October 24, 2005Publication date: May 24, 2007Inventors: Jorge Orbay, Javier Castaneda, Cesare Cavallazzi

Publication number: 20070093835Abstract: A fracture fixation system includes a plate having a first suture anchor location having an opening at the upper surface of the plate, an opening at the proximal end of the plate, and an opening at the anterior side of the plate and defines first and second suture pathways which cross within the plate. The first and second suture pathways include a common opening. A second suture anchor location on the plate has an opening at the upper surface of the plate, an opening at the proximal end of the plate, and an opening at the posterior side of the plate which defines third and fourth suture pathways which cross within the plate. The third and fourth suture pathways also share a common opening. Thus, each suture anchor location is capable of providing a hold for suture from multiple approaches to secure tuberosities relative to the plate.Type: ApplicationFiled: August 24, 2006Publication date: April 26, 2007Inventors: Jorge Orbay, Cesare Cavallazzi, Javier Castaneda

Publication number: 20070088360Abstract: A bone fixation system includes a plate and a set of fixation locking screws. The plate defines a set of locking screw holes each having an internal thread. Each respective locking screw has a head with an external structure that is adapted to self-tap into the internal thread of a given locking screw hole to secure the respective first-type fixation locking screw at an surgeon-directed angle relative to the plate. This angle is defined during forcible insertion and rotation of the respective locking screw into the given screw hole. The system may also include unidirectional locking screws. In a preferred embodiment the plate and first-type of screw are made of different metals, with the plate made of titanium alloy and the screw made of cobalt chrome alloy.Type: ApplicationFiled: March 20, 2006Publication date: April 19, 2007Inventors: Jorge Orbay, Alfredo Casteneda, Javier Castaneda, Robert Sixto, Edward Mebarak

Publication number: 20060276795Abstract: One or more small plates is provided for the fixation of the scapholunate interval between scaphoid and lunate. In one embodiment, a plate is fixed to the bones with fixed angle fasteners to allow complete healing and remodeling of the scapholunate ligament. In another embodiment, the system includes two small plates for the scaphoid and lunate joined by a central element. In yet another embodiment, the system includes two bone anchors for the lunate and scaphoid, also joined by a central element. The central element is flexible, and/or the plates or anchors are movably joined to the central element. The central element in each of these embodiments acts like an artificial ligament and permits more normal motion of the wrist bones while maintaining the scapholunate interval at its correct anatomical dimension.Type: ApplicationFiled: May 30, 2006Publication date: December 7, 2006Inventors: Jorge Orbay, Jose Nunez, Javier Castaneda
