Study of Experimental Cervical Spondylotic Myelopathy

Abstract

the single compression group showed normal limb function, but the multiple compression group showed sluggish gait. Histologically, mild neuronal decrease in the gray matter was noticeable in the single compression group. Conversely, the multiple compression group showed severe changes in the gray matter and significant changes in the posterior and anterior columns. There was a correlation between the evoked spinal cord potentials and histologic changes. It was clear that multiple compressions to the spinal cord caused more severe deterioration functionally and electrophysiologically as well as histologically than a single compression.
