METHOD FOR ASSESSING THE RISK OF DEVELOPMENT OF DEGENERATIVE CHANGES IN ADJACENT SEGMENTS AFTER PERFORMANCE OF DORSAL DECOMPRESSIVE-STABILIZING INTERVENTIONS ON THE LUMBAR SPINE Russian patent published in 2021 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to surgery, traumatology and orthopedics, and can be used to assess the risk of degeneration of adjacent segments after performing dorsal decompression and stabilization interventions (DSI) in patients with degenerative diseases of the lumbar spine. The body mass index and the degree of degeneration of the adjacent intervertebral discs are determined. Lumbar spondylography is performed, determining the value of angulation of adjacent segments. Risk factor parameters are assessed as follows: body mass index values ​​greater than 25 kg/m² are evaluated as 3 points, and body mass index values ​​less than or equal to 25 kg/m² are evaluated as 0 points. Grade III, IV degeneration of adjacent intervertebral discs according to the Pfirrmann classification is assessed as 2 points, and the degrees of degeneration of adjacent intervertebral discs less than degree III according to the Pfirrmann classification are assessed as 0 points. Angulation values ​​of adjacent segments less than or equal to 10.5° are evaluated as 1 point, and angulation values ​​of adjacent segments greater than 10.5° are evaluated as 0 points. The degree of risk of developing degenerative changes in adjacent segments is determined as the total number of points, summed up for all parameters. With a score of 0-2, the risk of developing degenerative changes is assessed as low and minimally invasive surgery is performed. With a total score of 3, the risk of developing degenerative changes is assessed as medium and surgical intervention is performed using minimally invasive stabilizing systems. With a score of 4-6, the risk of developing degenerative changes is assessed as high and surgical prophylaxis is performed by installing stabilizing structures on the adjacent segment.

EFFECT: method provides an increase in the reliability of determining the risk of developing degenerative conditions of adjacent segments by increasing the information content of the selected parameters of risk factors and ensuring their quantitative assessment.
