The present disclosure is directed to an implant that can be placed between two vertebrae using a lateral, anterior or posterior insertion method. The implant is characterized by having a first endplate and a second endplate, both endplates having inner surfaces that oppose each other when anchored into opposing vertebral bodies. The inner surfaces give rise to two articulating elements, each articulating element including two compatible units that mate and allow motion of the spine, including flexion, extension, lateral motion and rotational movement.
