Abstract
A surgical method, tool, and system to facilitate spinal surgery includes locating an inferior pedicle and guiding a bone cutting device to the inferior pedicle. The bone cutting device is used to remove a necessary portion of the vertebral body to provide access to the disc space. Typically the bone cutting device is removed and a speculum is inserted along the bone cutter guide until the speculum contacts a disc annulus between the inferior vertebral body and a superior vertebral body. The speculum is moved to ensure the nerves are out of the surgical area. The speculum also provides a shield to inhibit inadvertent damage to the nerve why the surgeon is operating.
