Abstract
In some embodiments, system and/or method may include an intervertebral implant for a human spine including an upper body, a lower body, first and second expansion members, and an expansion mechanism. A superior surface of the upper body may function to engage a first vertebra of the human spine. An inferior surface of the lower body may function to engage a second vertebra of the human spine. The first expansion member may include at least a first angled portion positionable, during use, between the upper body and the lower body. The second expansion member may include at least a second angled portion positionable, during use, between the upper body and the lower body. An expansion mechanism may convey, during use, the first and second angled portions in opposing directions increasing a separation distance between the upper body and the lower body.
