We reported 5 cases of cervical osteochondrosis with muscle atrophy, particularly in the shoulder girdle.
Muscle atrophy was almostly localized at C5 & C6 myotomes, but in myelopathy case, muscle atrophy was also seen at more caudal myotomes.
Sensory disturbance was seen in 4 cases, but lightened in degree compaired with muscle atrophy. In 1 case (radiculopathy), sensory disturbance was absent. Biceps tendon reflex was diminished in all cases. In a case (myelopathy), knee jerk was accelerated, but pathological reflex was absent.
On X-ray findings, spondylotic changes were seen in all cases predominant at the level of C4-5, C5-6 intervertebral discs. Myelogram revealed partial and/or complete block at the level of C4-5, C5-6 intervertebral discs.
We suggested that the level of the lesion was in C4-5 & C5-6 from the view point of neurological and X-ray findings.
