Occipitocervical fusion.

The evolution of occipitocervical fixation and new rigid universal screw-rod construct technology has allowed secure anchorage at each level of the occipitocervical junction with the elimination of rigid external orthoses. Rigid occipitocervical instrumentation constructs have achieved higher fusion rates and less postoperative immobilization-associated complications. Outcomes have improved compared with former nonrigid instrumentation techniques; however, with advances of rigid occipitocervical stabilization capability have come new challenges, risks, and operative techniques.

Navigated placement of iliac bolts: description of a new technique.

Background Context: Image navigation has improved the safety and ability to perform complex spinal procedures where visibility is not optimal or anatomic deformity is present. Numerous published studies are available demonstrating its effectiveness in improved pedicle screw placement in complex multiplanar deformities. Studies have also demonstrated image navigation technology versatility; however, stabilization of the lumbopelvic junction with navigated iliac bolt fixation has not been reported.
