This case involves a 48 year old male who underwent a micro discectomy at L3-L4. Immediately following the procedure the patient experienced numbness in his legs along with the inability to void his bladder. An MRI was performed the day after surgery and revealed a large extradural defect at L3-L4 juncture, which was consistent with a large central disc herniation. A second surgery was performed the following day that revealed a calcified annulus with resultant stenosis and compression of the thecal sac. The second surgery did not relieve that patient’s symptoms and currently he is non ambulatory and wheelchair bound. The final diagnosis was severe cauda equina with foot drop.
