Method of laterally inserting an artificial vertebral disk replacement implant with curved spacer
First Claim
1. A method of inserting an intervertebral implant comprising the steps of:
- a. accessing a lateral side of adjacent vertebral bodies;
b. cutting a receiving channel into a vertebral body, wherein the receiving channel extends between a first lateral end of the vertebral body and a second lateral end of the vertebral; and
c. inserting an implant into the receiving channel.

Abstract
The present invention is directed to an implant that can be placed between two adjacent vertebral bodies using a lateral insertion method. The implant is characterized as having a first end plate and a second end plate which a crossbar spacer therebetween. The crossbar spacer preferably fits within a channel on the inner surfaces of the first end plate and the second end plate, whereby the spacer allows pivots, twisting and/or rotational movement of the spine. The first end plate and the second end plate include a keel extending therefrom, whereby the keel traverses longitudinally between a first lateral side and a second opposed lateral side and is substantially perpendicular to the sagittal plane of the patient'"'"'s spine.

26. A method of inserting an implant comprising:
-
a. accessing a lateral side of an upper vertebral body and a lower vertebral body;
b. cutting a first keel receiving channel into the upper vertebral body, wherein the first keel receiving channel extends between a first lateral side and a second lateral side of the vertebral body;
c. cutting a second keel receiving channel into the lower vertebral body, wherein the second keel receiving channel is substantially parallel to the first keel receiving channel; and
d. inserting a first keel of an implant into the first keel receiving channel and a second keel of the implant into the second keel receiving channel, wherein the implant includes a spacer having opposing first and second curved surface oriented perpendicular to one another. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
