This minimally invasive technique is used to remove the herniated portion of a vertebral disc. This procedure is very effective in reducing or eliminating pain caused by nerve compression in the leg (sciatic). This surgery is performed through a small incision on the back.

A small incision is made over the herniated disk so the surgeon can make a small opening in the lamina. The compressed nerve root and the herniated disc can be seen through this "window".

The surgeon uses a nerve retractor to gently move the spinal nerve away from the herniated disc. The herniated portion of the disc is removed, eliminating pressure on the nerve root. Only the damaged portion of the disc is removed, leaving any healthy disc to perform its function as a cushion between the vertebrae.
