1. An anterior cervical plating system comprising:

  • at least one pre-positioned cervical plate defining a cervical plate body having a lower horizontal face configured to be disposed adjacent a first vertebral body and an upper horizontal face opposite said fewer horizontal face, and having at least a first vertebral anchoring mechanism configured to attach to the first vertebral body and at least one interlocking portion arranged on the cervical plate body along a longitudinal axis thereof;

    at least one revision cervical plate defining a revision plate body having at least a second vertebral anchoring mechanism configured to attach to a second vertebral body and at least one armature extending from the revision plate body along a 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 of the pre-positioned cervical plate to provide a stabilizing interconnection between adjacent pre-positioned cervical plate and the revision cervical plates, the stabilizing interconnection being capable of resisting movement of the adjacent cervical plates in at least one dimension;

    wherein the cooperative interlocking portion of the revision cervical plate is configured such that it initially engages the interlocking portion of the pre-positioned cervical plate from above the upper horizontal face of the pre-positioned cervical plate;

    wherein no threaded connector is inserted through or between any portion of the at least one armature in forming and permanently securing the stabilizing interconnection between the interlocking portion of the pre-positioned cervical plate and the cooperative interlocking portion of the revision plate; and

    wherein the cooperative interlocking portion of the revision plate does not directly anchor into the first vertebral body or the second vertebral body when the stabilizing interconnection is made.
