Some cases of spinal cord compression syndrome at the cervical osteochondrosis are difficult enough to distinguisch from the other diseases.
Case I: Muscle atrophy of the left hand is remarkable, but none of subjective and objective symptome in the right hand.
Case II: Only muscle atrophy of the right schoulder is noted, but none symptome of the both lower extrimities.
Case III and IV: ataxic gait is remarkable with sensory disturbance.
Case V: ataxic gait is remarkable without sensory disturbance.
We supposed that Case I and II were caused by lesion of the one side anterior column, and that case III and IV were caused by lesion of the bilateral posterior column chiefly rather than lateral corticospinal tract, and that case V by bilateral spinocerebellar tract.
