摘要：
An implant may provide a body capable of being fit in an intervertebral space and a spin-plate rotatable with respect to the body. The spin-plate may a blade. The blade may possess grooves in its flat faces, or may be provided with an overhang. The path of the overhang or groove may be such that as the spin-plate advances in its rotation, a vertebra engaged with the blade is drawn toward the body of the implant. Pins may be placed in adjacent vertebrae such as to engage the spin-plate. Surgical methods are also described.
