Objective This article presents 32 cases of thoracolumbar fracture with partial paraplegia treated with pedicle screws internal fixation indirect decompression of spinal canal or decompression of cord.

Objective To evaluate the clinical accuracy of computer-assisted fluoroscopy for the placement of thoracolumbar pedicle screws.
