First Claim
Patent Images
1. An anterior cervical plate comprising:
- a revision-capable cervical plate body formed of metallic material having upper and lower horizontal faces, wherein at least a portion of the lower horizontal face is configured to be disposed adjacent a first vertebral body;
at least one vertebral anchoring hole configured to provide an attachment point for an anchoring mechanism to attach the revision-capable cervical plate body to the first vertebral body; and
at least one interlocking portion arranged on the revision-capable cervical plate, the at least one interlocking portion of the revision-capable cervical plate being configured to cooperatively engage at least one cooperative interlocking portion of a revision cervical plate to provide an interconnection therebetween;
wherein the interlocking portion is configured such that the cooperative interlocking portion would at least partially overlap therewith in forming the interconnection;
wherein no threaded connector passes into the interlocking portion in forming the interconnection; and
wherein the anchoring mechanism is not partially or wholly disengaged from the first vertebral body in forming the interconnection.

Abstract
An improved anterior cervical plating system and methods of cervical fusion using such a system are provided. The cervical plating system includes an interlocking mechanism that integrated into each of the plates such that any two plates may cooperatively engage through the interlocking mechanism such that a new cervical plate can be interconnected with a pre-existing plate during revision surgery without removal of the pre-existing plate.
