Abstract

The present application is directed to instruments and methods for preparing a space between vertebral members. One embodiment of the instrument may include an elongated shaft with a proximal end and a distal end. A blade may be positioned at an end of the shaft and may rotate about an axis. The blade may include one or more teeth that include a height and/or contour. During rotation of the blade, the teeth contact and cut into one of the vertebral members. The instrument may also include a depth stop that limits a depth that the teeth can cut into the vertebral member. In some embodiments, the instrument includes a second blade that is configured to cut into the second vertebral member.
