1. 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 retention structures on 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
wherein the step of advancing the fixation device through the first vertebraincludes advancing the fixation device through a spinous process of the first vertebra.

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.
