Minimally Invasive Lumbar Discectomy


Minimally Invasive Lumbar Discectomy is a surgical procedure used to treat herniated or damaged discs in the lumbar region of the spinal cord. The minimally invasive technique involves smaller cuts and is less pain than the traditional open surgical procedure. It also offers quicker recovery compared to an open procedure. Lumbar discectomy might be required when you experience pain, inflammation in the lower back radiating pain in the leg, or a tingling sensation in the legs or numbness in the floor scatica.

Alternate Name

Microendoscopic lumbar discectomy

Body Location

Lumbar (lower back) region of the spine

How Performed

Minimally invasive lumbar discectomy is performed under sedatives and anaesthesia to block the pain and sensation. Small incisions are made in the skin of your lower back region to access the target location. Tubular dilators are inserted through the incisions to tunnel through the muscles. The endoscope is inserted through the dilators to create images of the damaged area while the surgery is being conducted. A variety of instruments are used through the dilators to remove the herniated or damaged disc from the lumbar region. Sometimes, fusion could be done to stabilise the spine in certain patients.


  • Prior to undergoing minimally invasive lumbar discectomy, you will need to undergo certain blood tests and a pre-anesthesia check-up (PAC) that would also include a chest X-ray, electrocardiogram (ECG) along with a physical examination to assess your suitability for the surgery. In addition, your doctor will have you undergo certain imaging tests such as Magnetic Resonance Imaging (MRI), and spine xrays.
  • Eat light food the day before surgery and fast for 6-8 hours before the surgery, to avoid complications.
  • Inform your surgeon if you are on any medications. You may be asked to discontinue blood-thinning medication. You may also be prescribed medication to calm your nerves.
  • You should reach the hospital 2-4 hours before the surgery as you will be kept under observation for some time.
