Reposition-locking device for minimally invasive treatment of compression fractures of the spinal column

摘要

Reposition-fixing apparatus for minimally invasive treatment of compression fractures of the vertebral column relates to the field of medicine and can be used for minimally invasive treatment of compression fractures of thoracic and lumbar spine with pedicle submersible systems. The apparatus includes two pairs repositioned in bushings, made in the form of hollow tubes passing distally into a conically-pointed cylinder, hinges with stoppers disposed on repositioned in sleeves and interconnected with rods reposition the handles. On the rods made multidirectional repositioning external threads. The apparatus allows repositioning steps (distraction, reclination) separately and with varying amplitude of each element repositioning dosed smoothly and without abrupt oscillations and displacements of structures spinal motion segments.
