METHOD OF SURGICAL TREATMENT OF OSTEOCHONDROSIS OF LUMBARY SPINE OF SPINE WITH MULTI-LEVEL STENOSIS OF SPINAL CANAL

摘要

FIELD: medicine.;SUBSTANCE: cut the skin from the posterior middle access in the projection of the spinous processes of the revealed segment of the lumbar spine, followed by dissection of the subcutaneous tissue and its own fascia. Perform skeletonization of spinous processes, arcuate articulations and arcs to the base of the transverse processes. Perform a revision and decompression of the vertebral canal in the identified segment of the lumbar spine with excision of the yellow ligament. A disk is approached by displacing a dural sac and root, which is followed by dissecting the disk and removing it with using scoops, discotomy and laminotomy instruments. Place two pairs of transpedicular screws in the adjacent vertebrae of the previously identified segment of the lumbar spine, with the correctness of their placement being controlled by the image intensifier. Stacking in any order on the heads of two pairs of unstable segment of transpedicular screws located in adjacent vertebrae, two metal fixing bars of metal fixation with length of 50 mm each, made of non-deformed material with a thermomechanical shape memory based on titanium nickelide intermetallide or from a copper system alloy of 14 wt % of aluminium - 4 wt % of nickel. They fix two metal fixing rods of metal fixation with nuts pre-placed on the head of the transpedicular screws.;EFFECT: method allows to restore the configuration of the spinal canal, provide early rehabilitation.;1 cl
