Back pain is a common ailment that affects millions of people worldwide, and herniated discs are a frequent culprit. As medical research advances, we are gaining a deeper understanding of the factors that contribute to disc degeneration and herniation. One question that often arises is whether herniated discs can be inherited. In this article, you will learn about the genetic components of disc degeneration, the role of family history, and what current research tells us about the inheritability of herniated discs.
Before addressing the genetics, let us briefly review what a herniated disc is. The spine is made up of vertebrae separated by cushion-like discs. A spinal disc has a tough outer layer (annulus fibrosus) and a soft, jelly-like center (nucleus pulposus). A herniated disc, also known as a slipped disc or ruptured disc, occurs when the soft center pushes through a crack in the tougher exterior. This can irritate nearby nerves, causing pain, numbness, or weakness in an arm or leg.
While a herniated disc itself is not directly inherited, the predisposition to disc degeneration, which can lead to herniation, does have a genetic component. Several studies have shown there is a hereditary aspect to disc degeneration, which increases the risk of developing herniated discs.
One of the most compelling pieces of evidence for the genetic influence on disc degeneration comes from twin studies. A landmark study published in Spine examined 115 pairs of twins and found that genetic factors accounted for 74 percent of the variation in disc degeneration in the upper lumbar spine and 73 percent in the lower lumbar spine.
Another study in Arthritis & Rheumatology that looked at 172 monozygotic and 154 dizygotic twins concluded the heritability estimate for disc height narrowing was 73 percent. These findings suggest a strong genetic component in disc degeneration, which is a precursor to herniation.
Researchers have identified several genes that may play a role in disc degeneration:
It is important to note that having these genetic variations does not guarantee you will develop a herniated disc. Rather, they increase your susceptibility to disc degeneration, which in turn raises the risk of herniation.
While genetics plays a significant role, environmental factors also contribute to the development of herniated discs. It is the classic nature vs. nurture debate. Some environmental risk factors include:
The interplay between genetic predisposition and environmental factors is complex. For example, a person with a genetic susceptibility to disc degeneration who also has a physically demanding job may be at higher risk for developing a herniated disc than someone with the same genetic makeup but a sedentary lifestyle.
Given the genetic component, family history can be an important indicator of your risk for developing herniated discs. If your parents or siblings have a history of herniated discs or chronic back problems, you may be at increased risk. However, it is crucial to remember this does not mean you are destined to develop these issues.
A study published in the journal Spine found that individuals with a family history of lumbar disc herniation had a significantly higher risk of developing the condition themselves. This underscores the importance of being aware of your family medical history and taking proactive steps to maintain spine health if you have a family history of disc problems.
Understanding the genetic component of disc degeneration and herniation does not mean you are powerless against your genes. There are several steps you can take to reduce your risk and maintain a healthy spine:
As our understanding of the genetic factors influencing disc degeneration grows, so does the potential for targeted treatments and prevention strategies. Some exciting areas of ongoing research include:
While you cannot directly inherit a herniated disc, the genetic factors that predispose you to disc degeneration—and consequently, disc herniation—can indeed be passed down through families. However, genetics is just one piece of the puzzle. Environmental factors, lifestyle choices, and preventive measures all play crucial roles in determining whether you will develop a herniated disc.
Understanding your genetic risk can empower you to take proactive steps to maintain your spine health. By combining this knowledge with a healthy lifestyle and proper back care, you can significantly reduce your risk of developing herniated discs, regardless of your genetic predisposition.
Remember, if you have concerns about your risk for herniated discs or are experiencing back pain, it is always best to consult with a healthcare professional. The doctor can provide personalized advice based on your individual health history and risk factors.
If you have a herniated disc that is not responding to conservative treatment, a surgical procedure called a discectomy may be discussed and potentially recommended. Even though discectomy surgery is a common and generally quite successful procedure, a hole is frequently left in the outer wall of the disc. In fact, patients with these large holes in their discs are more than twice as likely to reinjure themselves by having what is known as a reherniation. These reherniations often require additional surgery, which may even include spinal fusion surgery. Fortunately, there is a new treatment specifically designed to close the large holes that are often left in spinal discs after discectomy surgery. Barricaid is a bone-anchored device proven to reduce reherniations, and 95 percent of Barricaid patients did not undergo a reoperation due to reherniation in a 2-year study timeframe. This treatment is done immediately following the discectomy—during the same operation—and does not require any additional incisions or time in the hospital.
If you have any questions about the Barricaid treatment or how to get access to Barricaid, ask your doctor or contact us today.
