The patient came to the clinic 18-February-2008 complaining of LBP with right sciatica for 6 days. He had similar attack 1 year ago, but with lesser degree and extended for 5 days.

The patient was limping with scoliotic stance and had weak dorsiflexion right foot. SLRS was 50 degrees in the right and 80 degrees in the left.

The patient was sent for MRI of the lumbar spine, which was performed 20-February-2008 confirming the presence of huge disc L5-S1 with right downward migration.

Right L5-S1 hemiflavotomy was performed and foraminotomy of right S1 root was achieved. The extruded disc under the root was identified and removed in piece-meal fashion, after what the root became lax. The disc material was old and sequestrated. After cleaning of the extrusion, the root regained normal position, but it was swollen.

Right sided cleaning of the disc space of L5-S1 was performed. The disc space was not shallow.

Routine closure of the wound and smooth postoperative recovery.
