Abstract: Mochida K. et al.: Regression of cervical disc herniation observed an magnetic resonance images. Spine 23 (1998) 990-997 Previous studies have demonstrated that herniated cervical disc materials tend to regress but that this regression differs based on the anatomic position of the extruded material. This study sought to further clarify the morphologic changes over time with cervical disc herniation (CDH). A total of 38 patients with CDH who underwent repeated magnetic resonance imaging (MRI) examinations were studied. The changes in herniation patterns were evaluated over time. These patterns included midline or lateral as well as protruding or migrating. Patients were also followed for clinical outcome. A correlation was made between the changes in herniation patterns and outcome. The results revealed than in 15 and 38 patients (40%) there was a decrease in the volume of the herniated material over time while in 60% of the patients there was no change. Cervical disc herniations which were of the migratory type an the sagittal view and of the lateral type an the axial view demonstrated spontaneous regression more frequently than did those with other patterns (p < 0.02 and p < 0.05 respectively). Of note all patients with radicular pain and upper limb amyothrophy were successfully treated with conservative therapy. Conclusion: This study suggests that patients with a migratory pattern of disc herniation which was lateral in location seemed to demonstrate the greatest amount of spontaneous regression. All patients with radicular pain and amyotrophy in this study enjoyed good relief with conservative treatment. schö
