METHOD FOR DYNAMIC STABILIZATION OF LUMBOSACRAL VERTEBRAE BETWEEN THE LAST LUMBAR VERTEBRA AND THE FIRST SACRAL VERTEBRA IN DOGS AND DEVICE FOR DYNAMIC STABILIZATION OF LUMBOSACRAL VERTEBRAE BETWEEN THE LAST LUMBAR VERTEBRA AND THE FIRST SACRAL VERTEBRA IN DOGS Russian patent published in 2024 - IPC A61B17/70 A61F2/28 A61D1/00 

FIELD: medicine; orthopedics; veterinary science.

SUBSTANCE: group of inventions can be used for dynamic stabilization of the last lumbar vertebra and the first sacral vertebra of the lumbosacral spine in dogs. Lumbosacral spine is approached, bodies of the last lumbar vertebra and the first sacral vertebra of the lumbosacral spine are moved apart and the disc is removed, inserting in its place a cage with a hole in the central part and roughness on the outer surface, which are protrusions with a height of not more than 0.5 mm, so that the roughness is turned to the surface of these vertebrae; abdominal wall is closed. With subsequent approach to the lumbosacral spine in a prone position, after installation of four screws with tuning-fork open heads with a screw thread, a pair of screws is inserted into the body of each vertebra from the outside. Screws are inserted transpedicularly into the base of last lumbar vertebra peduncle, and transpedicularly into the joint facets of first sacral vertebra. Body of the last lumbar vertebra and the body of the first sacral vertebra of the lumbosacral spine are tightened to each other with the help of a pair of flexible cords, fixed by the ends in the screw heads on each side of the vertebrae with locking screws, the incisional wound is closed. Device comprises a cage with a hole in the central part and roughness on the outer surface, which are protrusions with a height of not more than 0.5 mm, made for installation between the body of the last lumbar vertebra and the body of the first sacral vertebra of the lumbosacral spine. Each pair of tuning-fork screws with open heads with a screw thread inside on one side of the body of the last lumbar vertebra and the body of the first sacral vertebra of the lumbosacral spine on the same side is connected in pairs to each other by a flexible cord, the ends of which are fixed by locking screws screwed into the screw thread of the tuning-fork open heads screws.

EFFECT: group of inventions provides higher efficiency of surgical correction of spinal deformities due to reduced risks of screw fracture and wider range of products in treating this type of diseases.
