What is sciatica? 

Sciatica is a term used to describe the presence of symptoms affecting the low back and legs. Symptoms are caused by an irritation or compression of one or more of the nerve branches in the lower back that join to form the larger sciatic nerve. The sciatic nerve may also be compressed by muscles as it extends down the leg. 

Often originating in the spine, sciatica can have several different causes. They include:

How is sciatica diagnosed? 

To diagnose sciatica, your physician will review your health history and perform a physical examination. Your doctor may also recommend diagnostic imaging, such as an X-ray or MRI, to assist in diagnosis.

What are the surgical treatment options for sciatica? 

If you are not finding relief from your sciatica with nonsurgical methods, it may be time to consider surgery. The specific surgical procedure your doctor recommends will depend on what is causing your sciatica symptoms. 

Common surgical options to relieve sciatica include: 


The most common surgery for herniated discs is called a “microdiscectomy.” In this surgery, a one- to two-inch incision is made in your spine on the side of the herniation. The surgeon then finds the herniation and removes the herniated piece. The surgery usually lasts about one to two hours, and many people feel better right upon waking up. 

Disc replacement surgery 

Disc replacement is most effective when the source of the pain is contained in the disc and the disc alone, and when the patient meets other qualifications, including a healthy weight, no prior major spine surgery, and no deformity in the spine.
