Cervical myelopathy due to ossification of the posterior longitudinal ligament.

Ossification of the posterior longitudinal ligament in the cervical spine may be a cause of cervical myelopathy. This ossification has often been encountered in Japan, but only sporadically among the Caucasian races. It is therefore probable that racial factors are relevant to the pathology. During the past four years, due to the routine use of computerised axial tomography (CAT) in the pre-operative study of cervical myelopathy, we were able to show that in 13 cases stenosis of the vertebral canal was due to ossification of the posterior longitudinal ligament. This was visible in the standard radiographs in only two out of these 13 cases. The clinical data, diagnostic criteria and results of treatment are reported. This is the largest series yet reported outside Japan.

Cervical myelopathy. Technique and results of spinal cord decompression by lateral laminectomy.

The Authors describe the technique of lateral laminectomy devised by Gui in 1965 for the treatment of cervical myelopathy secondary to cervical spondylosis. Spinal cord decompression is obtained by a lateral laminectomy with the maximum saving of bone, ligaments and muscles of the cervical spine. CAT scan demonstrated very well the effective decompression of the spinal cord achieved with this technique. The results of 87 cases treated in this way between 1968 and 1980 are reported. The average follow-up was 2.5 years. There was an improvement in the neurological symptoms in 82% of the cases.

Sacral agenesis: usefulness of CT study.

The authors report on a case of sacral agenesis evaluated by Computed Tomography (CT) of the spine. Sacral agenesis is an exceedingly rare, nongenetic, developmental anomaly which consists in an absence of the entire sacrococcygeal complex. Although maternal diabetes appears to be the most important etiologic factor, the significant teratogenetic effects related to maternal diabetes are not yet completely understood. Only few cases have been reported in neurological and neurosurgical literature because most authors believe that the neurological deficits associated with sacral agenesis are static and, therefore, myelography and surgical approach are useless. However, sacral agenesis can be surgically treated when dural sac stenosis is evident in presence of progressive neurological deficits. The usefulness of CT in depicting nervous anomalies which may favorably respond to surgical treatment is emphasized, in particular when compared with contrast myelography. CT scan seems able to replace contrast myelography in delineating the intraspinal nervous anomalies, thus avoiding the myelographic risks.
