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.

21. A method of providing spinal fixation, comprising the steps of:
-
advancing a fixation device that comprises a body having a first portion that forms a bone anchor and a second portion that forms a proximal end;
through a portion of a first vertebra;
advancing the bone anchor of the fixation device into a second vertebra;
advancing a proximal anchor distally along the fixation device;
proximally retracting the body of the fixation device with respect to the proximal anchor to adjust compression across the first and second vertebrae; and
advancing the fixation device through a spinous process of the first vertebra. - View Dependent Claims (19, 20, 22, 23, 24, 25, 26, 27, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
