First Claim
Patent Images
1. An anterior cervical plating system comprising:
- at least one pre-positioned cervical plate having at least a first vertebral anchoring mechanism and at least one interlocking portion arranged on the body of the cervical plate along the central longitudinal axis thereof;
at least one revision cervical plate having at least a second vertebral anchoring mechanism and at least one armature extending from the body of the revision cervical plate along the central longitudinal axis thereof, the at least one armature having a cooperative interlocking portion disposed thereon;
wherein the at least one cooperative interlocking portion of the revision plate is configured to cooperatively engage the at least one interlocking portion to provide a stabilizing interconnection between two adjacent plates, the stabilizing interconnection being capable of resisting movement of the adjacent cervical plates in at least one dimension; and
wherein the stabilizing interconnection between the interlocking portion of the pre-positioned cervical plate and the cooperative interlocking portion of the revision plate is accomplished without a threaded connector.

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.

20. An anterior cervical plating system comprising:
-
at least one pre-positioned cervical plate having at least a first vertebral anchoring mechanism and at least one interlocking portion arranged on the body of the cervical plate along the central longitudinal axis thereof; at least one revision cervical plate having at least a second vertebral anchoring mechanism and at least one armature extending from the body of the revision cervical plate along the central longitudinal axis thereof, the at least one armature having a cooperative interlocking portion disposed thereon; wherein the at least one cooperative interlocking portion of the revision plate is configured to cooperatively engage the at least one interlocking portion to provide a stabilizing interconnection between two adjacent plates, the stabilizing interconnection being capable of resisting movement of the adjacent cervical plates in at least one dimension; wherein the interlocking portion the of pre-positioned cervical plate comprises a groove integrally formed into at least one of the distal and proximal ends of the body of the cervical plate, and wherein the armature of the revision plate is interlockingly cooperative with said slatted groove; wherein the groove is slotted, and the armature has a cooperatively interlocking latch integrally formed on a portion thereof; and wherein the stabilizing interconnection between the interlocking portion of the pre-positioned cervical plate and the cooperative interlocking portion of the revision plate is accomplished without a threaded connector.
