Cervical myelopathy due to ossification of the posterior longitudinal ligament: a clinicopathologic study.

A clinicopathologic study was done of a Japanese patient with symptomatic ossification of the posterior longitudinal ligament in the cervical spine. Post-mortem specimen showed characteristic distribution of degenerations at C5-6 segments similar to chronic cervical spondylosis or disk protrusion. The degenerative changes were confined to the ventral two thirds of the posterior and lateral columns. In addition to demyelination, loss of axons, and neuronal cell death, thickening of venular wall and fine capillary neovascularization strongly suggested chronic circulatory insufficiency. Spinal immobilization produced by the ossified ligament may have contributed to the long clinical course, lasting for 30 years. Review of literature showed that the myelopathy can be distinguished clinically and radiographically from that produced by cervical spondylosis.

Juvenile type of distal and segmental muscular atrophy of upper extremities.

Seventy-one cases of distal and segmental muscular atrophy of the upper extremities with juvenile onset were studied. The clinical features consisted of: juvenile onset, male preponderance, unique distribution of the muscular atrophy in the hand and forearm, tendon reflexes hypoactive in most cases but hyperactive in some, no definite sensory disturbances, no involvement of the cranial nerves, and autonomic nerve disorders in the affected region. There was rapid progression during the 2 to 3 years after onset with a slowly progressive course thereafter. There were no abnormal laboratory findings except for electrophysiological and morphological findings of the affected muscles. The site of lesion was surmised to be from the C5 to T1 spinal segments with intramedullary involvement. The cause is unknown.
