METHOD FOR PREDICTION OF RISK OF DEVELOPING HETEROTOPIC OSSIFICATION CENTERS AFTER PERFORMING TOTAL ARTHROPLASTY OF INTERVERTEBRAL DISCS Russian patent published in 2021 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgery, spinal surgery, traumatology and orthopedics and can be used for prediction of risk of heterotopic ossification centers after performing total arthroplasty of intervertebral disks. After performing total arthroplasty of intervertebral discs by determining clinical-X-ray parameters: sex, value of motion amplitude in operated spine, height of intervertebral disc before operation, number of operated segments, tobacco smoking. Severity of the established parameters is evaluated in points, at the same time: female gender corresponds to value of 0 points, male sex - 1 point; amplitude of movements in cervical spine: 50° and more - 0 points, less than 50° - 1 point; amplitude of motions in lumbar spine: 35° and more - 0 points, less than 35° - 1 point; height of gage interval before operation: 6.0 mm or more - 0 points, less than 6 mm - 2 points; number of operated segments: more than 1 segment - 0 points, on one segment - 1 point; smoking: non-smokers - 0 points, smoking - 1 point. Specified points are summed up and a total score of 0 to 2 shows a low risk, 3 to 4 points shows an average risk and a value greater than 4 points shows a high risk of developing heterotopic ossification centers.

EFFECT: method enables evaluating the risk of developing heterotopic ossification following the operation of total arthroplasty of cervical and lumbar intervertebral discs in nearest 5-year postoperative period due to use of said diagnostic parameters.
