The present disclosure relates to an intervertebral implant that can be surgically introduced between adjacent vertebral bodies and adjusted or expanded in situ to occupy an optimal or desired space between the vertebral bodies. The implant is preferably inserted into the evacuated disc space obliquely and then oriented so as to extend laterally across the anterior adjacent vertebrae bodies occupying the disc space with the outer ends of the implant being supported by the cortical rims on the opposite sides of the vertebrae bodies. The implant has two body members with a space therebetween so the implant may be then distracted and a spacer of a, predetermined thickness may be inserted within the space between the body members so as to maintain a desired amount of distraction. The upper and lower surfaces of the implant may have a desired lordotic angle. A method of using an implant is also disclosed.
