The paper deals with microsurgical treatment of multi-levelled lumbar discogenic lesions. Fundamental interventional principles including preservation of the supportive ability of vertebromotor segments, reparative surgical techniques, and intraoperative procedures for prevention of scarring and adhesive processes are shown. Criteria for choosing the scope of an intervention in multi-levelled lumbar discogenic pathology are presented. The surgical policy proposed ensures the maximal decompression of neural and vascular structures of the vertebral canal, improves the outcomes of treatment, and reduces the number of reoperations.
