Facet Screw And Method For Spinal Stabilization

US Patent:
2013022, Aug 29, 2013
Filed:
Feb 23, 2012
Appl. No.:
13/403098
Inventors:
Moti Altarac - Irvine CA, US
Joey Reglos - Lake Forest CA, US
John Fredrick Stephani - Soquel CA, US
International Classification:
A61B 17/70
A61B 17/88
US Classification:
606247, 606279
Abstract:
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.

Anterior Cervical Plate

US Patent:
2013002, Jan 24, 2013
Filed:
Jul 19, 2011
Appl. No.:
13/185641
Inventors:
Moti Altarac - Irvine CA, US
Joey Reglos - Lake Forest CA, US
John Fredrick Stephani - Soquel CA, US
International Classification:
A61B 17/88
A61B 17/80
US Classification:
606279, 606290
Abstract:
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.

Appl. No.:
15/904983
Inventors:

Lateral Plate

US Patent:
2017002, Jan 26, 2017
Filed:
Oct 10, 2016
Appl. No.:
15/289855
Inventors:
- Henderson NV, US
Joey Reglos - Lake Forest CA, US
Michael Schneier - Las Vegas NV, US
Brian Stuart Grossman - Camarillo CA, US
Michael Davis - Henderson NV, US
Dale Lawrence Leibert - Moorpark CA, US
John Fredrick Stephani - Soquel CA, US
International Classification:
A61B 17/70
A61B 17/86
A61B 17/80
Abstract:
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.

Facet Screw And Method For Spinal Stabilization
