Abstract
In various embodiment of the invention an implant 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 there between. The crossbar spacer preferably fits within a channel on the inner surfaces of the first end plate and the second end plate, where the spacer allows the first end plate to pivot, twist and/or rotate relative to the second end plate. The first end plate and the second end plate include a keel extending therefrom, where 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.
