METHOD OF CORRECTIVE VERTEBROTOMY Russian patent published in 2023 - IPC A61B17/56 A61B5/107 

FIELD: traumatology and orthopedics.

SUBSTANCE: invention can be used for the correction of kyphotic deformity. Resection is performed in the frontal plane, posterior median approach, section of both pairs of articular processes, and closure of the defect in the dorsal sections. At the preoperative stage, multislice computed tomography (MSCT) is performed. On a sagittal section of the spine, the angle of kyphotic deformation is determined according to Cobb. Then, on the sagittal section of the spine, the correction angle CAB equal to the angle of kyphotic deformity according to Cobb is drawn, for this, for pairs of articular processes located on the same side, apex A is determined — the caudo-dorsal point of the body of the overlying vertebra from the damaged one, point B of the angle is determined on the lateral parts of the lower articular process of the overlying vertebra from the damaged one, point C of the angle is determined along the lateral surface of the lower edge of the upper articular process of the damaged vertebra. Similar points A1B1C1 are constructed for the opposite pair of articular processes, with the angle C1A1B1 equal to CAB. Next, resection is carried out in the frontal plane, a posterior median approach, a section of both pairs of articular processes, and closure of the defect in the dorsal sections. The lower articular processes of the overlying vertebra are resected in the AA1BB1 plane in the anterior and upward direction, the upper articular processes of the damaged vertebra are resected in the AA1CC1 plane in the anterior and upward direction. The lower articular process of the overlying vertebra is closed with the upper articular process of the damaged vertebra in the BB1CC1 plane.

EFFECT: method provides correction of kyphotic deformity in any part of the spine with low trauma due to the small volume of resection and complete closure of the bone defect.
