METHOD OF PREVENTION OF VERTEBROMEDULLAR CONFLICT IN ASYMMETRIC VARIANT OF TYPE 3-4 VERTEBROTOMY UNDER SCHWAB Russian patent published in 2023 - IPC A61B17/70 

FIELD: medicine, spinal surgery.

SUBSTANCE: invention can be used to prevent vertebromedullary conflict in asymmetric version of type 3–4 vertebrotomy under SCHWAB. The dorsal bilateral access to the operated spine is performed. Support transpedicular screws are installed in the pedicles of the vertebrae. A pedicle screw is installed in the projection area of the pedicle root of the vertebra to be toured along the concave side of the deformity. By means of corrective sectoral vertebrotomy, the deformed spine is mobilized. Transpedicular rods are installed. One-stage correction of spinal deformity in the frontal plane is carried out by a compression maneuver on the convex side of the scoliotic curve. Holding the tomed vertebra by the screw, the spine is fixed in the achieved position by the transpedicular system. Spinal fusion is created using autobone.

EFFECT: method reduces the likelihood of vertebromedullary conflict during asymmetric vertebrotomy due to the fact that in the process of performing a corrective maneuver, rotation of the vertebra to the concave side and posterior translation of the toned vertebra are excluded and vertebromedullary conflict with spinal cord compression at the level of vertebrotomy does not occur.
