Imaging of the patient on admission. Lateral radiograph (a) shows a fracture of the L1 vertebral body. On the axial (d) computed tomography, the retropulsion of bone fragments into the spinal canal is evident. Magnetic resonance imaging of T2-weighted image (b, c) also showed that bone fragments had retropulsed into the spinal canal and the dural sac was severely compressed. The images of the patient were reexamined on the first day after PPSF. The sagittal (e) and axial (f) computed tomography showed that the size of the fracture fragments in the spinal canal had decreased. The images of the patient were reexamined on the 3rd day after the second operation. The sagittal (g) and axial (h) of the computed tomography showed no residual bone fragments in the spinal canal and complete decompression of the spinal cord
