Abstract:
An intervertebral disc prosthesis comprises a superior endplate and an inferior endplate. The superior and inferior endplates include vertebra fixation surfaces designed to engage vertebral bodies. A composite material is provided on the vertebra fixation surfaces. The composite material includes an osteoconductive component and an osteoinductive component. The osteoconductive component provides a porous matrix or base that facilitates bone growth. The osteoinductive component provides a stimulant material that encourages growth of the bone cells between the osteoconductive component of the endplate and the vertebral body facing the endplate. In one embodiment, the osteoconductive component is permeated by an osteoinductive material to provide the composite material. In another embodiment, the composite material includes a non- resorbable portion that includes osteoconductive substances and a resorbable portion that is doped with osteoinductive substances.
