Abstract
A spinal fusion implant for implantation between adjacent vertebrae is formed in the approximate shape of a hollow cube. The device has an upper section and a lower section separated by a distractor all of which are relatively movable. The sidewalls of the upper section and the lower section terminate in inclined planes so that the sections move away from each other as the wedge shaped distractor increases the height of the device.
