Abstract:
1. A method of treating the spine comprising: creating a first intraosseous channel through a pedicle of a first vertebra directed from a posterior aspect to an anterior aspect of the pedicle along a first axis; inserting a cannula into at least a portion of the first intraosseous channel along the first axis, wherein the cannula comprises a bifurcation at a distal end region; positioning over the cannula an extracorporeal surgical guide comprising a first port and a second port, wherein the cannula extends through the first port; aligning the second port with a second axis directed from a posterior-caudal aspect to an anterior-cephalad aspect of the pedicle, wherein the second axis is off-set from the first axis by an angle; and creating through the second port a second intraosseous channel through the pedicle of the first vertebra directed along the second axis, wherein a most posterior extent of the second intraosseous channel is confluent with a most posterior extent of the first intraosseous channel.
