What Does a Discectomy Fix?
Chronic back pain and radiating nerve symptoms can significantly diminish quality of life, leaving many people searching for effective treatment options. When conservative treatments fail to provide relief, a discectomy may offer the solution patients need. In this article, we explore what conditions a discectomy addresses, how the procedure works, and what patients can expect from this common spinal surgery.
Understanding the Basics: What Is a Discectomy?
A discectomy is a surgical procedure designed to remove damaged portions of a spinal disc that are compressing nearby nerves. The spine consists of vertebrae separated by intervertebral discs, which act as cushions and shock absorbers. When these discs become damaged or herniated, they can press against spinal nerves, causing pain, numbness, and weakness.
During a discectomy, a surgeon removes the portion of the disc that is pressing on the nerve root or spinal cord. This procedure can be performed as an open surgery or, more commonly today, as a minimally invasive procedure called microdiscectomy, which uses smaller incisions and specialized instruments.
Primary Conditions a Discectomy Fixes
Herniated discs
The most common condition a discectomy addresses is a herniated disc, also known as a slipped disc or ruptured disc. This occurs when the soft gelatinous center of a spinal disc pushes through a tear in the more rigid outer layer. The herniated material can compress nearby nerves, causing significant pain and neurological symptoms.
A discectomy removes the herniated portion of the disc, relieving pressure on the affected nerve. This procedure is particularly effective when the herniation is causing severe symptoms that have not responded to conservative treatments such as physical therapy, medications, or epidural injections.
Sciatica
Sciatica refers to pain that radiates along the path of the sciatic nerve, which runs from the lower back through the hips and down each leg. While sciatica can have various causes, it is most commonly the result of a herniated disc in the lumbar spine compressing one of the nerve roots that form the sciatic nerve.
When a herniated disc causes sciatica, a discectomy can provide significant relief. By removing the disc material pressing on the nerve root, the procedure eliminates the source of nerve compression. Many patients experience immediate or rapid relief from leg pain following the surgery, though numbness and weakness may take longer to resolve.
Spinal stenosis
Spinal stenosis involves the narrowing of spaces within the spine, which can put pressure on the nerves traveling through the spine. While stenosis often results from age-related changes such as bone spurs or thickened ligaments, bulging or herniated discs can contribute to this narrowing.
In cases where disc problems contribute to spinal stenosis, a discectomy may be performed as part of a broader surgical approach. The removal of problematic disc material can create more space for the nerves, reducing compression and associated symptoms.
Degenerative disc disease
Degenerative disc disease is not truly a disease but rather a condition where age-related wear and tear on spinal discs causes pain and other symptoms. As discs degenerate, they can bulge, herniate, or develop tears that irritate nearby nerves.
A discectomy can address the symptomatic aspects of degenerative disc disease by removing damaged disc portions that are causing nerve compression. However, it is important to note that the procedure does not stop the degenerative process itself, and patients may require additional treatments or lifestyle modifications to manage their condition long-term.
Radiculopathy
Radiculopathy is a condition caused by compression, inflammation, or injury to a spinal nerve root. This compression can result from herniated discs, bone spurs, or other spinal abnormalities. Symptoms typically include pain, numbness, tingling, or weakness that radiates into the arms or legs, depending on which nerve root is affected.
When a herniated disc causes radiculopathy, a discectomy offers a targeted solution by removing the disc material compressing the nerve root. This approach directly addresses the underlying cause of symptoms rather than simply masking pain.
Specific Symptoms a Discectomy Relieves
Beyond addressing specific conditions, a discectomy can effectively relieve a range of debilitating symptoms:
- Radiating pain - One of the most immediate benefits patients experience is relief from sharp, shooting pain that travels down the arms or legs. This radiating pain, often described as electric or burning, typically improves significantly after disc material is removed from the affected nerve.
- Numbness and tingling - Nerve compression can cause abnormal sensations in the extremities. By relieving pressure on the nerve, a discectomy allows normal nerve function to resume, gradually reducing numbness and tingling sensations.
- Muscle weakness - Compressed nerves may struggle to transmit signals properly, leading to weakness in specific muscle groups. Following successful discectomy surgery, patients often notice increased strength as nerve function recovers, though this process may take several weeks or months.
- Limited mobility - Severe disc-related pain can restrict movement and make daily activities challenging. By eliminating the source of nerve compression, a discectomy can restore mobility and allow patients to return to normal activities.
When Conservative Treatments Fail
A discectomy is typically considered when conservative treatments have failed to provide adequate relief after approximately six to twelve weeks. Conservative approaches include physical therapy, anti-inflammatory medications, pain management techniques, and epidural steroid injections.
However, certain situations warrant more immediate surgical intervention. These include progressive neurological deficits, such as worsening weakness or loss of bowel or bladder control, which may indicate cauda equina syndrome, a medical emergency requiring urgent surgical decompression.
What a Discectomy Does Not Fix
While a discectomy is highly effective for specific conditions, it is important to understand its limitations. The procedure does not address all types of back pain, particularly pain originating from facet joints, muscles, or other spinal structures not related to disc herniation.
Additionally, a discectomy does not prevent future disc problems. Patients remain at risk for developing new herniations or experiencing recurrent herniations at the same level, though these complications are relatively uncommon. The procedure also does not reverse the overall degenerative process affecting the spine.
Success Rates and Long-Term Outcomes
Discectomy procedures have high success rates, with studies showing 80 to 90 percent of patients experience significant relief from leg pain and radicular symptoms. The procedure is particularly effective when symptoms are primarily caused by a single herniated disc compressing a specific nerve root.
Recovery time varies depending on the surgical approach used. Minimally invasive discectomies typically involve shorter recovery periods, with many patients returning to light activities within a few weeks. Full recovery and return to strenuous activities may take several months.
While not appropriate for all types of back pain, a discectomy offers highly effective relief for carefully selected patients whose symptoms stem from disc-related nerve compression. When conservative treatments have failed and diagnostic imaging confirms appropriate surgical candidates, this procedure can restore quality of life and help patients return to the activities they enjoy. Consulting with a qualified spine surgeon can help them determine whether a discectomy is the right solution for your specific condition.
Although discectomy surgery is generally a very successful procedure, a hole is 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 or even fusions. 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.
