Information for the public
This procedure is done using local or general anaesthetic, with the patient lying face down. It aims to relieve sciatica by removing tissue from the damaged disc.
A small cut is made in the lower back and, using X‑ray imaging to identify the correct place, a guide wire is inserted. An endoscope (a thin tube with a camera on the end) and special instruments are inserted and used to remove tissue from the damaged disc. A laser may also be used to help remove the tissue. The patient can usually get up within a few hours of the procedure.
