METHOD OF EVALUATING DEFICIT OF SPINAL CANAL LUMEN Russian patent published in 2010 - IPC A61B6/04 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and can be used in traumatology, orthopedics, neurosurgery, vertebrology and radiology for evaluating deficit of spinal canal lumen. From a series of images two images of axial section in uninjured zone and zone with the most expressed deficit of spinal canal lumen are selected. On each of said images additional plotting is carried out, on axis of vertebra symmetry and further, at equal distance from each other. Straight lines, parallel to axis of vertebra symmetry, are drawn, crossing with these lines contour of spinal canal from each side. On each of two selected images determined are lengths of segments of drawn straight lines, limited by spinal canal contour. After that deficit of spinal canal lumen is determined.

EFFECT: method allows to determine deficit of spinal canal lumen and volume of surgical intervention.
