Screws and Graft Displacement
The patient is a 46-year-old male who had undergone the corpectomies of C5-6
and discectomies at C4-7 with anterior plate fusion and bone grafting for
cervical myelopathy resulting from cervical stenosis as well as kyphotic
deformity. Thereafter, the patient noted increased spasm of his right arm as
well as right leg. Work up revealed that the patient had dislodged the inferior
portion of the bone graft as well as the plate.
This post-operative radiograph suggests normal alignment of the bone graft
and fixation plate
|Scout image from a CT obtained 3 months later suggests ventral displacement of the
bone graft and fixation plate.
| This axial CT taken at the same time shows to
better advantage how the distal screws are fully out of the ventral cortex of C7
on the right hand distal screw and only 1 thread of the left hand distal screw
remains in the bone itself. The fixation plate is also 1cm ventral to the body
of C7 at this level.
