Adjustable Occipital Plate
First Claim
1. A fixation system for connecting a stabilization system to a bone, the fixation system comprising:
- a base plate having a midline and adapted to be mounted to the bone;
at least one attachment assembly coupled to the base plate at a variety of positions relative to the midline of the base plate;
a joint construct mounting the attachment assembly to the base plate; and
a rod selectively coupled to the base plate via the attachment assembly at a variety of positions relative to the midline of the base plate.

Abstract
An occipital plate for use in an occipito-cervico-thoracic (OCT) construct is mounted to a patient'"'"'s occipital bone. The occipital plate includes an elongate base plate oriented with a midline of the base plate longitudinal on the occipital bone. A pair of lateral sections project in opposite directions from the central section and include attachment assemblies for securing a rod to the occipital plate. The position of the attachment assembly relative to the midline of the occipital plate is adjustable to thereby provide for medial-lateral adjustability. In specific embodiments, the attachment assemblies include a slide member which mates with the lateral section of the occipital plate in a dove-tail joint configuration and a set screw is threadably engaged with the slide member to secure the slide member relative to the midline of the occipital plate and the appropriate spacing and geometry for the specific patient. The set screw also secures a cam, which fixes the rod to the occipital plate.
