METHOD OF TRANSFORAMINAL INTERBODY FUSION AND ROTATED PUSHER Russian patent published in 2019 - IPC A61B17/56 A61F2/44 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely to vertebrology, and can be used for transforaminal interbody fusion. One-sided resection of hypertrophied articular processes of facet joint is performed. Carry out the entrance to the spinal canal and partial decompression of the roots of the spinal cord. Resected bone tissue is preserved and milled. Complemented root is shifted in medial direction. Disc herniation and osteochondral growths are resected. In opened after displacement of root of fibrous ring of intervertebral disc with scalpel, a window is cut, through which discectomy and curettage of disc is performed. Adjacent bone plates of adjacent vertebrae are cleaned until blood dew appears. Tongue of interbody spacing is performed. Cage is filled with autogenous crumbs and the obtained implant is inserted into an interbody space in a sagittal plane and shifted in the disk cavity on the opposite "healthy" side, keeping its position strictly in a sagittal plane. Rotary pusher (RP) is installed in the gap between the lateral edge of the implant and the lateral edge of the hole in the fibrous ring by orienting the RP blade in the sagittal plane. RP rotates through 90 degrees, the RP blade to translate into the horizontal plane, moving the implant towards the midline. RP is transferred into a sagittal plane. In the gap formed between the RP and the implant, a larger RP is installed. Rotating RP of larger size by 90 degrees to bring the blade into horizontal plane, moving the implant even further towards the midline. RP of larger size is transferred into sagittal plane and both RP are removed. To RP of smaller size RP of larger size is installed in horizontal plane with subsequent turn into sagittal one. In the gap between the RP of larger size and the implant in the sagittal plane, a RP of an even larger size is set and rotated by 90 degrees, moving the implant even further. Successively increasing size of RP, performing similar manipulations before implant installation into required position. RP is removed. Second cage is filled with autogenous crumbs and the obtained implant is inserted into an interbody space parallel to the first implant. RP for implementing the method of transforaminal interbody fusion comprises a guide and a pushing part, guide is made in form of rod and is equipped with L-shaped handle installed on end of rod, pushing part is located on rod opposite end from handle and is made in the form of flat blade with width of 8 mm, or 9 mm, or 10 mm, or 11 mm, or 12 mm , or 13 mm, or 14 mm with a rounded edge on side ends and with a rounded wedge-shaped face in front part.

EFFECT: group of inventions enables to move the implant in a direction perpendicular to the axis of the pusher, enabling correction in the sagittal plane.
