Posterior arthrodesis of the spine by percutaneous CT-guided application of screws: preliminary report.

We report our preliminary results obtained in five patients following a percutaneous posterior arthrodesis of the spine, executed under fluoroscopic control and CT guidance. To benefit from a mechanical fixation after an anterior osteosynthesis without the inconveniences of the classic posterior surgical intervention, we have adopted a procedure performed under local anesthesia and based on the intraarticular application of screws. The procedure is CT-guided, resulting in a perfect localization of the area involved, it is safe, and it is performed in a short time limiting, therefore, possible neurological, vascular, or visceral complications.
