[Effect of the sequence of intermediate instrumentation and distraction-reduction of the injured vertebra on the treatment of thoracolumbar burst fractures with high rate of spinal canal encroachment].

In the treatment of patients with thoracolumbar fractures with high rate of spinal canal encroachment, short-segment percutaneous pedicle screw internal fixation with distraction-reduction first and then intermediate instrumentation and sequential distraction-reduction again can more effectively reduce the bony encroachment in the spinal canal and achieve indirect decompression effect better.
