Abstract
An anatomical study was conducted to evaluate the emergence of spinal roots at different levels and their relation to the intervertebral foramena. A percutaneous needie was thernnserted in the direction of these roots and their contact studied under direct vision and by X-rays. These results were compared with those obtained in 50 patients who underwent spinal rhizotomies. There is a direct correlation between the anatomy at different levels and the quality of relief obtained after surgery.
