Posttraumatic instability and myelopathy
in a 82–year–old man. The patient died one week after he had a
two–segment fusion with bone grafting and anterior titanium locking
screw–plate fixation. The screw tracts were filled with a blue
casting medium. This sagittal section displays the (paramedian)
screw tracts in C3, C4 and C5. Note the corticocancellous bone
grafts. The C3–C4 segment is high anteriorly and lower posteriorly.
In both interspaces large posterior disc remnants cause the intact
outer annulus fibrosus to protrude into the spinal canal and to
compress the spinal cord.
