Abstract
A method of positioning a cannula along a path in a patient's intervertebral plane, comprising: suspending a cross member across a patient, the cross member having two cannula guides attached thereto, the cannula guides each being adjustably movable both along the length of the cross member and around a central longitudinally extending axis of the cross member; suspending radiopaque markers from the cannula guides; aligning the radiopoaque markers with the intervertebral plane as viewed in a radio-image, thereby aligning the cannula guides with the intervertebral plane; and advancing a cannula through the cannula guide.
