Abstract
Disclosed is a fixation device that includes an elongated body including a bone anchor at a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device. In one embodiment, the device is advanced through a spinous process of a first vertebra, inserted through the first vertebra and the bone anchor is rotated into position within a second vertebra. The proximal anchor is distally advanced with respect to the bone anchor to provide compression across the first and second vertebrae.
