頸髄損傷の分析

抄録

50 cases which had been treated in our clinic for the last 3 years were analyzed from miscellaneous angles.
1. As traumatic mechanism to the cervical spine, axial compression, hyperflexionn, hyperextension, whiplash, rotation and “unknown” are listed.
2. As factors causing myelopathy to the cervical cord, dislocation, fracture, intervertebral sliding, angulation, posterior spur, ossification of the posterior longitudinal ligament, anomaly developmental stenosis and “unknown” are listed.
3. Relationships between these mechanism and factors were discussed.
The spinal cord surounded by the narrow spinal (congenital or acquired) has tendency to be involved even by slight forces.
4. Traumatic cervical myelopathy was classified into 5 types due to parts of transverse cord lesions. i. e. anterrior, posterior, central, Brown-Sequard and transverse type.
5. Most of transverse type with severe paralysis changed into posterior and central type with slight paralysis in the last examination.
This means that traumatic myelopathy is caused by both damage and circulatory disturbance of the spinaal cord.
