Intraradicular, Intervertebral Disc Herniation

H Z Finkel

Abstract

STUDY DESIGN: A case of intraradicular, intervertebral disc herniation is reported. OBJECTIVES: A rupture of en L5-S1 intervertebral disc into the left S1 nerve root is described. SUMMARY OF BACKGROUND DATA: A review of the literature revealed five reported cases with some possible causes of this extremely rare phenomenon. METHODS: The diagnosis was made at the time of surgery during exploration of the L5-S1 disc space. The S1 nerve root was found to be adherent to the underlying disc space. Before surgery, this condition was believed to represent a large extradural and extraradicular disc herniation. RESULTS: The patient's pain was alleviated almost immediately after surgery, but the patient was left with some residual sensory loss in the leg. CONCLUSION: An unusual case of intraradicular, intervertebral disc herniation is presented.
