The relation between pain provocation and the degree of general degeneratin and anular disruption assessed according to the Dallas Discogram Description as indices of intradiscal deterioration was investigated. Pain provocation was also evaluated after categorizing the discs by the clinical diagnosis. Pain provocation showed little relation to intradiscal deterioration, whereas a strong relation was found between it and herniated nucleus pulposus. In herniated nucleus pulposus, discs with extrallgamentous extrusion or sequestration, large protrusions, maximum protrusion site at the nerve root portion, and herniation routes passing throughthe central portion of the disc showed a high pain provocation ratio. Pain provocation ratios of discs associated with spinal canal stenosis were extremely low., 名古屋大学博士学位論文 学位の種類 : 博士(医学)(論文) 学位授与年月日:平成4年12月11日 前沢祥司氏の博士論文として提出された}, school = {名古屋大学, NAGOYA University}, title = {Pain Provocation at Lumbar Discography as Analyzed by Computed Tomography/Discography}, year = {1992} }
