Results In 84 cases of nerve root type,stenosis was found in 438 intervertebral foramen,of which C6～7 and C5～6 intervertebral foramen stenosis accounted for 79.6%.The causes of intervertebral foramen stenosis were uncinate process articulation hyperosteogeny,intervenebral disc protrusion,vertebral body hypertrophy,zygapophysis hyperosteogeny and dislocation etc.40 cases of vertbral artery type manifested that vertbral artery became slim and deviousness as a result of the compression of vertbral artery （20.7%） by osteophyte.22 cases of myeloid type manifested with cervical spinal canal stenosis,hyperosteogeny of posterior vertebral body edge,posterior longitudinal ligament calcification and cervical intervertebral disc protrusion etc.
