SURGICAL TREATMENT METHOD OF LOW-DYSPLASTIC SPONDYLOLISTHESIS Russian patent published in 2019 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to orthopedics and vertebrology, and can be used for surgical treatment of low-dysplastic spondylolisthesis. Allocate displaced vertebra arc L5, a spondylolysis zone in the interarticular arc part, two spaces between arcs adjacent to the displaced vertebra arc on both sides, articular and transverse processes on both sides. Transpedicular screws are inserted into bodies of adjacent vertebrae. Roots L5, S1 from both sides and the dural sac are decompressed. Disk curettage is performed. Interbody implants are installed. Angular and linear angular displacement of vertebra is corrected, rods are fixed in transpedicular screws. After the transpedicular screws are installed, the displaced vertebra L5 arc is separated and removed. Performing decompression of roots L5, S1 and placing extracted arch L5 in place. On both sides through the lower articular process arches in upper articular process S1 vertebra perpendicular to plane of articular surfaces a pin is conducted. A channel is formed on the pin by a cannulated drill with diameter of 2 mm; a cannulated spongious screw with diameter of 2.5 mm and length of 2 cm is screwed on the spoke; the articular process of the arc is screwed tightly to the articular process of the sacrum.

EFFECT: method provides complete linear and angular reconstruction of displaced vertebra and improves clinical result by spinal cord root decompression and reliable interbody spondylolysis.
