1. An anterior cervical plating system comprising:

  • a first cervical plate formed of a metallic material having upper and lower horizontal faces, and at least one first vertebral anchoring point extending through the first cervical plate and configured such that a first vertebral anchoring mechanism may pass there through and attach the first cervical plate to a first vertebral body, wherein the first cervical plate is adapted to solitarily stabilize at least one level of a spine;

    a second cervical plate formed of a metallic material having upper and lower horizontal faces, at least one second vertebral anchoring point extending through the second cervical plate and configured such that a second vertebral anchoring mechanism may pass there through and attach the second cervical plate to a second vertebral body, and at least one cooperative interlocking portion is disposed thereon, wherein the second cervical plate is adapted to stabilize at least one other level of a spine;

    wherein the at least one cooperative interlocking portion of the second cervical plate is configured to overlap and cooperatively engage the first cervical plate to provide a stabilizing interconnection between the first and second cervical plates;

    wherein the first and second cervical plates are configured such that when an engagement between the first and second cervical plates is formed, the engagement is initially formed by positioning the cooperative interlocking portion of the second cervical plate above the upper horizontal face of the first cervical plate and moving a least a portion of the second cervical plate in a direction such that the cooperative interlocking portion engages with the first cervical plate;

    wherein the at least one cooperative interlocking portion is configured such that the formation of interconnection would not require that the first cervical plate to be partially or wholly disengaged from the first vertebral body; and

    wherein no threaded connector passes through the portion of the at least one cooperative interlocking portion overlapping the first cervical plate in permanently securing the stabilizing interconnection.
