SPINAL SPACER |
摘要 |
Spinal spacers (20) are provided for fusion of a motion segment. The spacers include a load bearing member (21) having a wall (22) sized for engagement within a space between adjacent vertebrae to maintain the space and an effective amount of an osteogenic composition (30) to stimulate osteoinduction. The osteogenic composition includes a substantially pure osteogenic factor in a pharmaceutically acceptable carrier. In one embodiment the load bearing member includes a bone graft impregnated in an osteogenic composition. In another embodiment, the osteogenic composition (30) is packed within a chamber (25) defined in the graft. Any suitable configuration of a bone graft is contemplated, including bone dowels, D-shaped spacers and cortical rings. |
