Abstract

A posterior vertebral plating system comprising a plate and a plurality of attachment members. The plate has a plurality of holes extending through the plate from an upper surface to a lower surface, and the plate is configured to extend along the posterior side of at least two vertebrae adjacent at least one boney structure of each of the vertebrae. The holes are spaced in such a way that a first plurality of holes is positionable over a boney structure of a first vertebra to define a plurality of fixation points to the first vertebra and a second plurality of holes is positionable over boney structure of a second vertebra to define a plurality of fixation points to the second vertebra. The attachment members are insertable through the holes of the plate and into the boney structure of a corresponding vertebra to fix the plate to the vertebra.

First claim

What is claimed is:

1. A posterior vertebral plating system, comprising:
a plate having a width, a length, a longitudinal axis extending along the length, an upper surface, a lower surface, and a plurality of holes extending through the plate from the upper surface to the lower surface, the plate being configured to extend along the posterior side of at least two vertebrae adjacent at least one lateral mass of each of the vertebra and the holes being spaced in such a way that a first plurality of holes is positionable over the lateral mass of a first vertebra to define a plurality of fixation points to the first vertebra and a second plurality of holes is positionable over the lateral mass of a second vertebra to define a plurality of fixation points to the second vertebra; and
a plurality of attachment members insertable through the holes of the plate and into a corresponding vertebra to fix the plate to the vertebra,
wherein the plate comprises a lateral mass plate portion and a lamina plate portion with the longitudinal axis extending therebetweeen, the plate being configured to be bent along the longitudinal axis between the lateral mass plate portion and the lamina plate portion, the lateral mass plate portion being attachable to lateral masses of corresponding vertebra and the lamina plate portion being attachable to lamina of corresponding vertebra with the attachment members,
wherein the lamina plate portion is formed of a plurality of tabs extending from one side only of the lateral mass plate portion, each of the plurality of tabs extending directly from the lateral mass plate portion along the longitudinal axis and being individually bendable relative to the lateral mass plate portion along the longitudinal axis.

2. The posterior vertebral plating system of claim 1 , wherein the plate has a longitudinal groove extending along the longitudinal axis between the lateral mass plate portion and the lamina plate portion to facilitate bending along the longitudinal axis.

3. The posterior vertebral plating system of claim 1 , wherein each tab has two holes.

4. The posterior vertebral plating system of claim 1 , wherein the lateral mass plate portion has one row of holes.

5. The posterior vertebral plating system of claim 4 , wherein each tab has two holes.

6. The posterior vertebral plating system of claim 1 , wherein the lateral mass plate portion has two rows of holes.

7. The posterior vertebral plating system of claim 6 , wherein each tab has two holes.

8. The posterior vertebral plating system of claim 1 , wherein the lateral mass plate portion has a perimeter edge on an opposite side to the plurality of tabs, the perimeter edge being configured to substantially conform to the contour of the holes in the lateral mass plate portion.

9. The posterior vertebral plating system of claim 8 , wherein the lateral mass plate portion has one row of holes.

10. The posterior vertebral plating system of claim 9 , wherein each tab has two holes.

11. The posterior vertebral plating system of claim 8 , wherein the lateral mass plate portion has two rows of holes.

12. The posterior vertebral plating system of claim 11 , wherein each tab has two holes.
