METHOD FOR COMBINED POSTER SPONDILODESIS AND BRACKET FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC A61B17/70 A61F2/44 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to neuro-orthopedics, neurosurgery, and can be used in the surgical treatment of degenerative lesions of the spine using dynamic systems to stabilize and fix the spinal motion segment without significant impairment of the motor ability of the spine. In the projection of the spinous processes, an incision of the skin and underlying soft tissues with a length of at least 6-8 cm is performed, after dissecting the aponeurosis, the spinous processes and arcs of two adjacent vertebrae are skeletonized on both sides of the spinous processes. After decompression of the nerve structures of the spinal canal with medial facetectomy, a hole is made on both sides in the interspinous gap and its dimensions are determined. A sized implant is inserted into the interspinous space while preserving the interspinous and supraspinous ligaments. After installing the interspinous implant, the staples are cooled to a temperature of 0-5°C, deformed with forceps to the desired shape and the bent end is installed in the diamond-shaped hole of the implant. A ridge with a rounded end is wound up behind the spinous process, then the staples are warmed with a tampon with saline at a temperature of 40-45°C. The bracket for combined posterior fusion is made of titanium nickelide and its dimensions correspond to the dimensions of the interspinous space. In working condition, it is a shape made in the U-form with a bent one end and the other end elongated in relation to the first at least 2 times, raised above the plane of the letter U at an angle of 110° and forming a circle in the upper part of the elongated end radius 2 mm.

EFFECT: invention provides a reliable dynamic fixation of the spinal motion segment, as well as a decrease in the invasiveness of the operation and an increase in the patient's safety due to the use of braces.
