Microdiscectomy is a surgical procedure used to treat a prolapsed or herniated disc pressing on a spinal nerve or the spinal cord. The protruding part of the disc is removed through an incision in the fibrous outer coat of the disc. The operation is performed under general anaesthesia and requires a brief stay in hospital.
