A widely performed surgery, microdiscectomy is considered to have relatively high rates of success, especially in relieving patients’ leg pain (sciatica). Patients are usually able to return to a normal level of activity fairly quickly.

Recurrence of a Disc Herniation

Estimates vary, but between 1% and 20% of people who have a microdiscectomy will have another disc herniation at some point.7

See What's a Herniated Disc, Pinched Nerve, Bulging Disc...?

An additional disc herniation may occur directly after back surgery or many years later, although they are most common in the first three months after surgery. If the disc does herniate again, a revision microdiscectomy will generally be just as successful as the first operation. However, after a recurrence, the patient is at a higher risk of further recurrences.

See Lumbar Herniated Disc: What You Should Know

For patients with multiple herniated disc recurrences, a spinal fusion may be recommended to prevent further recurrences. Removing the entire disc and fusing the level is the most common way to assure that no further herniated discs can occur.

See Lumbar Spinal Fusion Surgery

If the posterior facet joint is not compromised and other criteria are met, an artificial disc replacement, which removes the problematic disc and replaces it with an artificial one, may be considered.

See Artificial Disc Replacement Surgery

Following microdiscectomy spine surgery, an exercise program of stretching, strengthening, and aerobic conditioning is recommended to help prevent recurrence of back pain or disc herniation.

Microdiscectomy Potential Risks and Complications

As with any form of spine surgery, there are several risks and complications associated with a microdiscectomy.

A dural tear (cerebrospinal fluid leak) occurs in about 1% to 7% of microdiscectomy surgeries.8 The leak does not change the results of surgery, but the patient may be asked to lie down for one to two days after surgery to allow the leak to seal.

Other risks and complications include the following:

  • Nerve root damage
  • Bowel/bladder incontinence
  • Bleeding
  • Infection
  • Possible buildup of fluid in the lungs that may lead to pneumonia
  • Deep vein thrombosis, which occurs when blood clots form in the leg
  • Pain that persists after the surgery

See Failed Back Surgery Syndrome (FBSS): What It Is and How to Avoid Pain after Surgery

The above complications for microdiscectomy spine surgery are not common.
