Abstract
|
|
|
Discography was performed on the 2285 intervertebral disc spaces on the 1500 patients with herniated lumbar disc. Discographic findings were compared with those of lumbar myelography and / or lumbar computed tomography (CT), performed on the same patient. Among thse patients, 107 cases were operated on and the others were followed by 2mf of intradiscal chymopapain injection.
These results were analyzed and summarized as follows.
1) Cottonball type, biscuit type and bilocular type of discographic findings which were classified as normal conventionally were found in cases with definite clinical manifestation and abnormal findings in the myelography and CT studies. Accordingly, these types are no longer considered as normal variations.
2) A discography demonstrated the shape of disc and whereabout of intmdiscally injected materials very clearly. As far as concerned with this advantage the discography is superb than any other examination.
3) A discography, lumbar myelography, and lufnbar CT were not readily correlated and one of these studies is not superior to the others in diagnostic value. It is thought that these studies are supplemental to each other.
