[Pararectal miniinvazive retroperitoneal approach to the lumbosacral spine.]

The authors describe the technique of the anterior miniinvasive retroperitoneal pararectal approach to the lumbosacral spine. The technique was verified on cadaveric specimens.The miniinvasive operation requires a special set of instruments (a fixed frame), long instruments and a light cable. The advantage of the approach is a small peroperative traumatization and a relatively low labour intensity. The use of the miniinvasive technique requires a good knowledge of the technique of a routine extensive approach. Key words: surgical approaches, spine, lumbosacral spine.
