Background:
Posterior epidural lumbar disc fragment migration is rare and most commonly occurs at the L3-L4 level where it may contribute to cauda equina compression.
Case description:
Here, we report three cases of epidural migration of a lumbar disc, two of which led to bladder dysfunction/cauda equina compression. Early decompression (e.g., laminectomy) and aggressive postoperative physiotherapy led to significant postoperative improvement in all three patients.
Conclusion:
Migration of large sequestrated lumbar disc herniations leading to cauda equina compression should be recognized early and promptly treated with decompressive laminectomies to achieve the best postoperative outcomes.
