Abstract
A spinal assembly plate. The plate can have an uninterrupted passage to accommodate a portion of a vertebral screw there through at a non-predetermined location of the plate. An apparatus can be included with sidewalls to secure the plate there between. Another apparatus can be included with a face having a frictional character to longitudinally stabilize the apparatus to the plate. A spinal assembly can be included having a vertebral screw, a spinal plate, an apparatus to secure the vertebral screw, and a connector brace to stabilize the plate. In a method of the invention, a vertebral screw can be placed through an opening of a connector brace and into a vertebral body of a patient wherein the brace includes sidewalls to stabilize a spinal plate.
Claims13
A spinal assembly plate comprising:
- an elongated body having a longitudinal dimension suitable to be secured to a portion of a spine and having an uninterrupted, longitudinally extending passage defining an inner wall, said passage having a dimension to extend over a portion of said spine and to accommadate a portion of at least one vertebral screw extending therethrough at a non-predetermined position within the passage selected from boundless potential longitudinal positions, and said elongated body including an uninterrupted, longitudinally extending perimeter defining an outer wall a connector brace having a sidewall extending a portion of a length of said outer wall in a direction defined by an axis of the vertebral screw to couple adjacent said outer wall at a non-predetermined position along the perimeter selected from boundless potential longitudinal positions, and a nut having a face configured to be secured adjacent a surface of said elongated body and a coupling portion to secure said portion of said vertebral screw.
A kit comprising:
- a plate having a longitudinal dimension suitable to be secured to a portion of a spine, having an uninterrupted, longitudinally extending passage having a dimension to extend over a portion of the spine, and having an uninterrupted, longitudinally extending perimeter defining an outer wall;
- a nut having dimension to couple to the plate and to extend through the plate at a non-predetermined longitudinal position within the passage selected from an undetermined longitudinal adjustment distance within the passage;
- and
- a connector brace having a dimension to couple adjacent said outer wall at a non-predetermined position along the perimeter selected from boundless potential longitudinal positions.
A spinal assembly plate comprising:
- an elongated body having a longitudinal dimension suitable to be secured to a portion of a spine and having an uninterrupted, longitudinally extending passage defining an inner wall, said passage having a dimension to extend over a portion of said spine and to couple to a portion of at least one vertebral screw extending therethrough at a non-predetermined position within the passage selected from boundless potential longitudinal positions, and said elongated body including an uninterrupted, longitudinally extending perimeter defining an outer wall having a dimension such that a sidewall of a connector brace may be coupled adjacent said outer wall at a non-predetermined position along the perimeter selected from boundless potential longitudinal positions;
- wherein said elongated body further comprises a surface configured to be oriented towards said portion of said spine between said outer wall and said inner wall and said plate further comprises a connector brace, having a sidewall to be adjacent said outer wall and a base to be adjacent said surface oriented towards said portion of said spine:
- wherein the surface of said elongated body is a first surface, the elongated body further comprising a second surface terminating at said inner wall, said plate further comprising:
- a nut having a face configured to be secured adjacent said second surface of said elongated body and a coupling portion to secure said portion of said vertebral screw.
