Abstract
An intervertebral filling includes a supporting body, a buffer layer covering the supporting body and at least two positioning pins, each positioning pin has a sharp end exposed out of the buffering layer, and the intervertebral filling uses this sharp ends of the positioning pins to stay in two adjacent spinal vertebrae end-plates. The supporting body is a little harder than the buffer layer and is used for sharing stress in the spine, providing a strong support. Consequently, the intervertebral filling of the present invention remains stably positioned between the two adjacent spinal vertebrae end-plates without undergoing displacement.
