These cases resemble motor neuron disease in some features. Keegan (1965) investigated one autopsy case with such neurological symptoms and called this particular clinical syndrome “dissociated motor loss in the upper extremities with cervical spondylosis”. He concluded that its causative pathology was selective compression of the ventral motor roots intradurally. In 1965, we named this clinical syndrome “cervicalspondylotic amyotrophy (CSA)” and suggested that the mechanism of its development involved selective damage of the anterior horn of the spinal cord. The main clinical features of CSA are as follows:
