How Likely is Reherniation After Lumbar Discectomy Surgery?

    

How Likely is Reherniation After a Discectomy Surgery For decades, discectomy surgery has been the surgical gold standard for relieving leg pain caused by a lumbar disc herniation. The procedure itself proves very effective, generating an approximately 84 percent1 overall success rate. However, like any surgery, it’s not without risks, and not all patients carry the same risk level.

Reherniation is the most common complication after lumbar discectomy. In fact,  7-18 percent2 of discectomy patients experience recurrent disc herniation. If you’re considering a discectomy to reduce your pain and get back your daily life, the risk of reherniation and repeat surgery is certainly a concern—fortunately, there are ways to minimize the likelihood of recurrence. 

Below, we break down the primary risk factors that lead to reherniation and proactive ways to prevent it from occurring and minimizing the need for repeat surgery.

Common Risk Factors That Can Lead to Reherniation

Reherniation can lead to3 the need for repeat operations, which are typically not as successful as the initial procedure. Some of the common risk factors for reherniation include the following:

Activity Level

Patients living a sedentary lifestyle may be more likely to encounter poor outcomes. When our muscles are inactive for long periods of time, they become tense and stiff, which is thought to impede discectomy recovery. 

Body Mass Index (BMI)

Overweight herniated disc patients are more likely to require revision procedures. From a study of 226 patients4 across different weight ranges, the two-year risk for revision procedure was 1.8 percent for normal-weight patients, 12.5 percent for overweight patients, 9.1 percent for obese patients, and 25 percent for morbidly obese patients. In other words, the greater the BMI, the higher the risk of reherniation and repeat surgery.

Age

Like many other conditions age can play a factor in the likelihood of reherniation. While studies show mixed results, younger patients are believed5 to be at increased risk of needing revision surgery for a reherniation.

Tobacco Use

Smoking has proven to increase reherniation rates time and time again. It not only accelerates disc degeneration, but also interferes with tissue healing after surgery. A study revealed that patients who were smoking at the time of surgery had a 50 percent higher6 recurrence rate in contrast to non-smokers. As a result, it’s believed that smoking cessation may significantly reduce7 the incidence of recurrent lumbar disc herniation after discectomy. 

Diabetes

Multiple studies have shown that diabetic patients are at a higher risk when it comes to reherniation after a discectomy surgery. One study found that patients with uncontrolled diabetes had twice the recurrence rate8 after discectomy than those without. 

Large hole in the disc

Patients with a large hole (6mm or wider) in the outer ring of the disc, also known as an annular defect, are at a significantly greater risk of reherniation and recurring symptoms compared to those with small holes. Based on recent research, discectomy patients have a one-in-three9 chance of having a large annular hole in his or her disc.

Amount of Removed Disc Material

Your spine surgeon must decide whether to perform a limited or more aggressive discectomy. In an aggressive discectomy, the surgeon removes any free disc material as well as material from within the disc itself. On the other hand, a limited discectomy involves only removing any free disc fragments that are outside the disc without entering the disc space to remove additional material.

There are pros and cons to both approaches. A limited discectomy approach leads to a higher risk of reherniation10 when compared to a more aggressive removal of disc. That said, an aggressive discectomy can deflate the disc, resulting in loss of disc height over time (disc collapse), ultimately causing stiffness, pain and instability. Your surgeon can make an expert recommendation on the best treatment pathway for you.

How to Prevent Reherniation After Discectomy

While the risk of reherniation may be anxiety-inducing, it doesn’t have to prevent you from having your discectomy surgery to relieve debilitating pain. Along with cutting back on known risk factors like smoking, there are other steps you can take to prevent reherniation and the burden of repeat surgery.

Research shows11 that in patients with large holes in the disc, implantation of a bone-anchored annular closure device greatly reduces the risk of reherniation and the return of symptoms. One recent study12 found that the use of an annular closure device resulted in a 50 percent risk reduction when it comes to reherniation, reoperation, and complications.

The Barricaid device is specifically designed for patients with larger holes in their annulus, significantly improving the odds of a better discectomy outcome. It allows your spine surgeon to perform a less aggressive discectomy, preserving as much of your disc as possible and reducing the reherniation risk.

Next Steps

If you’re considering discectomy surgery to relieve pain from a herniated disc, it’s completely understandable that you may have concerns about the risk of reherniation. Being aware of risk factors and exploring the possibility of an annular closure device may decrease the likelihood of reherniation, recurring symptoms, and the need for surgery.
