Patent number: 11478283Abstract: An anterior cervical plate system is provided. The cervical plate includes a retention ring with a deflectable flange that is upwardly spaced from the top surface of the ring and configured to prevent an inserted bone fastener from backing out of the plate. The plate includes a locking pin having a camming surface and a blocking surface. When the camming surface is moved into position adjacent to the flange, the flange is free to flex out of the way of a bone screw being inserted into or removed from the plate. When the blocking surface is positioned adjacent to the flange, outward deflection of the flange is prevented to retain the bone screw inside the plate. The locking pin is rotated through a camming surface to bring a blocking surface against the flange deflecting the flange onto the head of the bone screw.Type: GrantFiled: January 7, 2021Date of Patent: October 25, 2022Assignee: Howmedica Osteonics Corp.Inventors: Moti Altarac, Joey Reglos, John Fredrick Stephani

Patent number: 9775652Abstract: A bone plate system is provided. The system includes two or more fastener locks stacked on top of each other and located between two holes in a plate adapted to receive bone fasteners. An actuator is provided between the locks. As the actuator is advanced, the locks are moved sequentially into position, firstly, to prevent one or more bone fasteners from backing out of the plate while permitting the fasteners to angulate and, secondly, to lock the angulation of the bone fasteners while still providing back out protection in situ. An expandable bone plate having a top plate interconnected to a bottom plate by a rack and pinion is provided. The rotation of the pinion with a driver lengthens or shortens the plate incrementally for custom length adjustment. The length is fixed in position with the simple removal of the driver and no further step is required to lock the plate length.Type: GrantFiled: October 10, 2016Date of Patent: October 3, 2017Assignee: Mastros Innovations, LLCInventors: Moti Altarac, Joey Reglos, Michael Schneier, Brian Stuart Grossman, Michael Davis, Dale Lawrence Leibert, John Fredrick Stephani

Patent number: 9649138Abstract: A spinal facet bone screw and minimally invasive surgical method of implanting a facet screw to stabilize the spine are provided. The facet screw includes an elongated body portion having a head, a threaded portion and a distal threadless portion. A pair of flutes formed in the elongated body extends from the distal end across the threadless portion and into the distal end of the threaded portion. The flute creates a self-tapping cutting surface that includes a heel edge that is curved with respect to the outer surface. The method of implantation comprises making a minimally invasive incision on the side of the midline contralateral to the target facet joint and delivering the screw across the interspinous process using the adjacent spinous processes as guideposts. The facet screw system fixes juxtaposed facet articular processes to enhance spinal fusion and stability and the method provides for accurate, repeatable and easy implantation.Type: GrantFiled: January 22, 2016Date of Patent: May 16, 2017Assignee: NeuroStructures, Inc.Inventors: Moti Altarac, Joey Reglos, John Fredrick Stephani
