This minimally invasive technique is used to remove the herniated portion of a vertebral disc. It is effective in eliminating leg pain (sciatica) caused by nerve root compression. The procedure is performed through a small incision on the back.
The surgeon creates an incision directly over the herniated disc, then opens a small window in the bone covering the spinal canal. The pinched nerve root and the herniated disc can be seen through this opening. The surgeon then uses a nerve retractor to gently move the spinal nerve away from the herniated disc.
Only the herniated portion of the disc is removed, eliminating pressure on the nerve root and leaving any healthy disc material to perform its function as a cushion between the vertebrae.
