Bony spinal canal changes that differentiate conjoined nerve roots from herniated nucleus pulposus

WK Hoddick and CA Helms

CT examinations of the lumbar spine in 12 consecutive patients with conjoined nerve roots were reviewed. Asymmetry of the bony spinal canal, seen as slight dilatation of the ipsilateral lateral recess, was present in all cases. This finding, which is not typically associated with extruded free intervertebral disk fragments, should serve to distinguish these two entities.
