Intrapedicular screw fixation of the spine has become increasingly popular in recent years. Transpedicle screw insertion may cause three types of complications: neurologic, vascular and mechanical. Potential compilications due to pedicle screw penetration of the anterior cortex of a vertebra include injury to vascular, visceral, ureteral, sympathetic and neural structures. Most neurological and mechanical complications mainly are attributable to orientation errors. Presented is a special treatment of a penetration of the aorta at a patient with a hypernephrom. The clinical case analysis radiographs, angiography, and computed tomograh images and describe the symptoms some years after spondylodesis and our treatment.

We think that a computer assisted technique is much more accurate and save than manual insertion. Some investigations shown a reduce of complications with a computer assisted surgery at spine.
