A Lumbar Microdiscectomy is performed to remove a prolapsed disc or disc fragments to relieve pressure on the spinal nerve roots. Pressure on the nerve root causes pain radiating into the corresponding side limb.

An x-ray will be taken during surgery and used to confirm the correct level of surgery.

A small cut is made in the middle of the back over the site of the prolapsed disc. With the help of a microscope the prolapsed disc is identified. Once identified, the prolapsed disc or disc fragments are removed from the spine.

The cut is closed with sutures
