Posterior vertebral plating system

摘要

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.

1. A posterior vertebral plating system, comprising:
a plate having 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 a posterior ring of a C1 vertebra to a posterior side of a C2 vertebra, the holes being spaced in such a way that a first plurality of holes is positionable over the posterior ring of the C1 vertebra to define a plurality of fixation points to the C1 vertebra and a second plurality of holes is positionable over the posterior side of the C2 vertebra to define a plurality of fixation points to the C2 vertebra; and a plurality of attachment members insertable through the holes of the plate and into the posterior ring of the C1 vertebra to the posterior side of the C2 vertebra to fix the plate to the vertebra, wherein the plate comprises:
a spacer portion having a first end and a second end and a longitudinal length generally corresponding to the distance between the posterior ring of the C1 vertebra and the lamina of the C2 vertebra;a ring engaging portion extending from the first end of the spacer portion and configured to extend along and conform to at least a portion of the posterior ring of the C1 vertebra; anda posterior engaging portion extending from the second end of the spacer portion and configured to extend along and conform to at least a portion of the posterior side of the C2 vertebra.
