Abstract:
1. An anterior cervical plating system comprising: at least one pre-positioned cervical plate 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 a first vertebral anchoring mechanism configured to attach to the first vertebral body, and at least one interlocking portion arranged on the pre-positioned cervical plate; at least one revision cervical plate defining a revision plate body having upper and lower horizontal faces, wherein at least a portion of the lower horizontal face is configured to be disposed adjacent a second vertebral body, at least a second vertebral anchoring mechanism configured to attach to the second vertebral body, and at least one armature extending from the revision plate, the at least one armature having a cooperative interlocking portion disposed thereon; wherein the at least one cooperative interlocking portion of the revision cervical plate is configured to cooperatively engage the at least one interlocking portion of the pre-positioned plate to provide a stabilizing interconnection between the pre-positioned and revision cervical plates, the stabilizing interconnection being capable of resisting movement of the pre-positioned and revision cervical plates; and wherein the engagement between the pre-positioned and revision cervical plates is initially formed by positioning the at least one armature of the revision cervical plate above the upper horizontal face of the pre-positioned cervical plate and moving at least a portion of the revision plate in the direction of the second vertebral body, and wherein the cooperative interlocking portion of the revision cervical plate is configured such that when engaged to the interlocking portion of the pre-positioned cervical plate a portion of the at least one armature is positioned atop a portion of the upper horizontal face of the pre-positioned cervical plate; and wherein no threaded connector passes through the portion of the at least one armature positioned atop a portion of the upper horizontal face of the pre-positioned cervical plate.
