METHOD OF SPINE REPOSITION AND FIXATION IN CASE OF COMMINUTED FRACTURES OF BODIES OF THORACIC AND LUMBAR VERTEBRAE Russian patent published in 2013 - IPC A61B17/00 A61B17/70 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to vertebrology. Via surgical access transpedicular screws are introduced through rooths of arches of adjacent vertebrae. After that transpedicular screw is introduced into large fragment of affected vertebra through Roy-Camille point. From the side of large fragment transpedicular screws are connected by means of bar, with rigid fixation in it of transpedicular screws, introduced into vertebra adjacent to affected one. Diastasis between fragments of affected vertebra is eliminated due to ensuring rotation of transpedicular screw, introduced into large fragment, around bar axis. The latter screw is fixed in bar. Transpedicular screw is introduced into second fragment of injured vertebra through contralateral point of Roy-Camille with ensuring its passage through the fracture line into first fragment. System mounting is finished by installation of second bar from the other side with rigid fixation of the remaining transpedicular screws in it. Bars are connected to each other by means of connector.

EFFECT: method increases reposition possibilities of internal system and ensures reliability of fixation of injured vertebra fragments.
