METHOD FOR DISCECTOMY FOR DEGENERATIVE CERVICAL SPINE DISEASE Russian patent published in 2023 - IPC A61B17/70 

FIELD: neurosurgery; traumatology.

SUBSTANCE: for simultaneous discectomy on two adjacent intervertebral discs, a fixed position of the cervical spine is achieved by moderately extending it by placing a pillow under the thoracic spine, placing a headrest under the occipital part of the head, and fixing the arms along the body. The access to the anterior surface of the cervical vertebrae is performed from a transverse skin incision located lateral to the midline to the outer edge of the sternocleidomastoid muscle. A radiological marker is placed over the vertebral body, which is the centre of the adjacent intervertebral discs to be operated on, and the two-staged discectomy is performed. At the first stage, discectomy is performed above the located intervertebral disc, for which the positions of the surgical table and the surgery microscope are changed so that the patient's legs are higher than the head and direct visualization of the working channel and anatomical corridor to the intervertebral disc located higher is achieved. At the second stage, discectomy is performed below the located intervertebral disc, for which the positions of the surgical table and the surgery microscope are changed so that the patient's legs are lower than the head and direct visualization of the working channel and anatomical corridor to the intervertebral disc located lower is achieved.

EFFECT: method provides reduction of pain syndrome, effective visualization of intervertebral discs of adjacent segments and the spinal canal in the area of surgical intervention without expanding access for implant installation, the possibility of using a standard set of surgical instruments due to the shortest trajectory from the skin incision to the anterior surface of the cervical spine and a standard interbody cervical retractor due to the absence of wide dissection and gross damage to the superficial fascia of the neck and paravertebral muscles, changing the angle of the surgical table and surgery microscope.
