The prolapsed intervertebral disc. The high-intensity zone with discography correlation

摘要: Study design The study compared the presence of high-intensity zone on magnetic resonance imaging with results awake discography. Objectives To see if there was a correlation between discography and imaging. Summary background data evaluation discogenic pain has proved to be somewhat elusive. Recent studies have indicated as being highly sensitive in diagnosis painful segment. present designed investigate whether is associated concordant response Methods Magnetic images were obtained 29 patients low back without radiculopathy. Consecutive considered for surgical intervention after falling respond conservative treatment. specifically looked within posterior anulus. Each patient subsequently underwent computed tomography. Computed tomography classified according Dallas Discogram Scale response. Chi-square analysis used calculate versus disc disruption Results There no statistically significant at any level. was, however, never seen morphologically normal disc. Conclusions Although anulus some abnormal discs, it not necessarily
