This invention is a device (10), and method for use in a human spine to prepare a space between adjacent vertebral bodies into the vertebral end plates to receive an implanting insert. The device (10) includes a handle (13), a shaft (12), and a mounting member (16) at one end of the shaft (12). An abrading element (18) is mounted on the mouting member (16) and is coupled to a drive mechanism (14). The drive mechanism (14) is operable to move the abrading element (18) in at least one degree of freedom to create surfaces having predetermined contours in the end plates of the adjacent vertebral bodies. |
