Abstract
An apparatus and method for fusing cervical vertebrae is provided. The apparatus may include a plate configured to be affixed to at least two vertebrae, and at least two screws configured to affix the plate to an anterior surface of the at least two vertebrae, wherein when the plate is affixed to the at least two vertebrae, the plate is configured to be partially disposed in a disc space between the at least two vertebrae, and extend in an anterior direction beyond an anterior surface of the at least two vertebrae.
Claims20
An apparatus comprising:
- a plate configured to be affixed to at least two vertebrae;
- and
- at least two screws configured to affix the plate to the at least two vertebrae;
- wherein the plate, when affixed to the at least two vertebrae, is configured to be partially disposed in a disc space between the at least two vertebrae, and extend in an anterior direction beyond an anterior surface of the at least two vertebrae.

A method for fusing two vertebrae, the method comprising:
- carving a channel between the two vertebrae;
- inserting a graft in the channel;
- affixing a plate to the two vertebrae such that a posterior portion of the plate is disposed within the channel, and an anterior portion of the plate extends in an anterior direction beyond an anterior surface of the two vertebrae.
An apparatus comprising:
- a plate configured to be affixed to two vertebrae;
- and
- two screws configured to affix the plate to the at least two vertebrae;
- wherein the plate comprises an anterior portion and a posterior portion;
- wherein, when the plate is affixed to the two vertebrae, the posterior portion is configured to be disposed in a disc space between the two vertebrae, and the anterior portion is disposed on an anterior surface of the two vertebrae;
- and
- wherein a cephalo-caudal height of the anterior portion is greater than a cephalo-caudal height of the posterior portion, and an anterior-posterior depth of the anterior portion is greater than an anterior-posterior depth of the posterior portion.
