The posterior longitudinal ligament might be ossified and enlarged with aging, and then the cervical spinal cord around the ligament is compressed. Moreover, the yellow ligament might loosen by deformed intervertebral disk, and then the cervical spinal cord around the ligament is compressed. These might develop at the same time, and the appearance of disease mechanism is not clear. In this paper, the stress distributions in the cervical spinal cord compressed by the posterior longitudinal ligament and yellow ligament were calculated by two-dimensional finite element method. The result that the possibility of the yellow ligament contact part of the spinal cord that is the boundary part of the posterior funiculus and the posterior horn is high and the appearance of disease mechanism of the cervical myelopathy and the acute traumatic central cord syndrome was almost the same was obtained.
