Abstract:
Objective: To find out the pathomechanism of low back and leg pain related to intervertebral disc. Methods: The nucleus pulposus of coccygeal vertebral was transplanted to the cavum epidurale of rats to establish the non-compressive model with transplanted nucleus pulposus. The evoke potentials and morphology of nerve roots were observed. Results: Even without mechanical compression, rats transplanted with nucleus pulposus resulted in significant harm to evoked potential and morphology of cauda equina. Conclusion: The biomechanical and/or immunologic inflammatory effect of nucleus pulposus can result in nerve roots injury and is an important factor in the pathogenesis of low back and leg pain.
