Percutaneous Discectomy for a Lumbar Herniated Disc

Percutaneous means “through the skin or using a very small cut. Discectomy is surgery to remove herniated disc material that is pressing on a nerve root or the spinal cord.

There are many different kinds of percutaneous discectomy procedures. All of them use small instruments that are inserted between the vertebrae and into the middle of the disc.

Most of the time they are done in a surgery center using local or general anaesthesia.

X-rays help guide the movement of the instruments during surgery. The surgeon can remove disc tissue by either:

  •   Cutting it out.
  •   Sucking out the center of the disc.
  •   Using lasers to burn or destroy the disc.

What To Expect After Surgery

You can expect to go home on the same day you have the procedure.

For several weeks after surgery, you’ll need to avoid long periods of sitting and avoid bending, twisting, and lifting.

Why It Is Done

Lumbar (low back) percutaneous discectomy may be done if:

  •  Your medical history, physical examination, and diagnostic tests (such as MRI, CT SCAN, OR MYELOGRAM) show that the disc is bulging, and the material inside the disc hasn’t ruptured into the spinal canal.
  •  Pain and nerve damage have not improved after 4 or more weeks of nonsurgical treatment.
  •  Your symptoms are very bad and get in the way of doing normal activities.
  •  There are signs of serious nerve damages in your leg that may be getting worse. These signs include severe weakness, loss of coordination, or loss of feeling.
