Abstract
Disclosed is a fixation device for spinal fixation. The fixation device includes an elongated body comprising 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 inserted through a first vertebra and the bone anchor is rotated into positioned within a second vertebra. The proximal anchor is distally advanced with respect to the bone anchor to provide compression across the first and second vertebra. In other embodiments, the device is used to secure stabilization devices across two or more vertebra.
