This is a minimally invasive technique that makes it possible to eliminate or extract disc hernias without the need for open surgery. By using nucleotomy the disc material is removed mechanically, the nerve is decompressed and the pain-causing pressure is relieved. Local anesthetic and sedation are used with radioscopy. A 24-hour hospital stay is required and a minimum stay in the city of 5 days is recommended.


Rhizolysis is carried out by using radiofrequency, and is a minimally invasive technique for treating painful symptoms when other conservative treatments have failed. This technique consists of applying a current to the nerve that transmits sensitivity by using an electrode with current flowing through it. This causes thermocoagulation in the nerves, which stop hurting. It is done using local anesthetic and does not require a stay in hospital.


This is advised for any patients suffering from pain in a leg caused by a disc hernia that does not diminish with non-surgical treatment (drugs, physiotherapy). It consists of extracting a small piece of the bone over the nerve root and/or disc material under the nerve root in order to relieve the pinching effect on the nerve and provide more space for the nerve to heal. The pinching on the nerve root (compression) can lead to great pain in the leg. Although weeks or months may be needed for the nerve root to heal completely and for any weakness or numbness to improve, patients normally feel relief from leg pain almost immediately after the operation. It requires a two-day hospital stay and a minimum recommended stay in the city of 5 days.
