[Topography of prevertebral structures in thoracic and lumbar spine.].

Authors describe the topographic relation of the anterior aspect of thoracolumbar spine to individual prevertebral structures (vessels, nerves, ligaments) as their injury may cause serious complications during spine surgery. Observations have been made on cadavers and checked by peroperative findings and findings on MRI sections. Having a good view of prevertebral anatomical structures has a principal significance for the use of anterior surgical approaches. Key words: topographic anatomy, thoracolumbar spine, MRI.
