Adjustable occipital plate
First Claim
1. An occipital plate, comprising:
- a base plate having;
an elongated central section with a midline; and
a first section and a second section projecting laterally outward in opposite directions from the midline of the base plate, wherein the first section comprises a slot; and
an attachment assembly having;
a slide member having a pair of opposing flanges projecting therefrom configured to engage and move along the slot of the first section; and
a post coupled to the slide member, wherein the post has a channel defined by a pair of opposing spaced-apart sidewalls extending therethrough;
wherein the channel is configured to receive a rod therein along an axis of the channel;
wherein the axis of the channel is rotationally offset from an axis extending centrally through each of the pair of opposing flanges;
wherein the attachment assembly is configured to self-align or essentially self-align with the rod as the rod is received in the channel of the post of the attachment assembly.

Abstract
An occipital plate may include a central section, a pair of angled sections, and attachment assemblies comprising slide members configured to move along slots in the angled sections, and posts coupled to the slide members. Each post has a first and second cross dimensions. The first cross dimension of each post is less than a first cross dimension of a slide member. The second cross dimension of each post is approximately equal to a second cross dimension of a slide member. Rods may be coupled to the occipital plate at a variety of angles with respect to a midline of the plate. The angular adjustability may accommodate any misalignments in the rods. Further, the position of the attachment assemblies relative to the midline is adjustable to thereby provide for medial-lateral adjustability when attaching the rods to the occipital plate as part of an occipito-cervico-thoracic construct.
