METHOD OF TREATING PATIENTS WITH LUMBAR SPINAL STENOS Russian patent published in 2017 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: after performing decompression on the ipsilateral side, the area of the housing of the spinous process is identified, through which with the help of a high-speed drill, access to the spongy bone in the contralateral arch of the vertebra is performed. In the course of the arch, a full-length drill is performed without damaging the yellow ligament and the posterior cortical plate of the arch at this stage. After passing the arch, a borer is removed into the cavity of the zygapophysial joint on the contralateral side. Further, the mobilization of the removable arch part and the lower zygapophysial joint is carried out by perforating the upper and lower cortical plates of the arch. Then the mobilized fragment of the cortical plate of the arch and yellow ligament is pressed into the drilled channel, its removal is carried out in parts or in one block. A medial resection of the upper zygapophysial joint is performed using a borer or osteotribe.

EFFECT: method reduces the risk of damage of the dural sac.
