頸椎症, OPLLに対するクラッチフィールド牽引による治療経験

抄録

Crutchfield traction was employed in the treatment of 40 cases of cervical spondylosis and 9 cases of OPLL. The treat ment was very effective in the radiculpathy group in cervical spondylosis, especially in those cases which showed a stenosis of the intervertebral foramen with less than 50 percent of its normal diameter in an oblique X-ray view, In the group of myelopathy in cervical spondylosis, its effect was related to the antero-posterior diameter of the cervical spinal canal. In the group of OPLL, its effect was not related to the rate of stenosis, but to the type of ossification.
