Should You Get Disc Replacement If Epidural Injections Wear Off Quickly?

Yes, you should consider artificial disc replacement surgery if epidural steroid injections provide only short-term pain relief. This pattern often indicates a structural problem, such as a disc herniation, rather than acute inflammation, which may require surgical intervention to restore spinal stability and function.

At Total Orthopedics and Sports Medicine, our doctors prioritize conservative pain management treatments, including epidural steroid injections, to help relieve radiating pain and avoid spinal surgery. However, if these treatments fail to provide lasting relief, we may recommend disc replacement surgery. In such cases, our experienced surgeons use minimally invasive techniques to lower complication risks and support a safe recovery. Call 855-321-6784 now to book your consultation.

When Do Doctors Recommend ADR Instead Of Repeating Injections?

Orthopedists may recommend artificial disc replacement (ADR) surgery when symptoms do not improve despite 3 to 4 epidural steroid injections within a year. They also consider surgical treatment if imaging confirms single-level disc degeneration or herniation that causes persistent pain and progressive neurological symptoms, such as numbness and muscle weakness.

In addition, artificial disc replacement spine surgeons may also recommend surgical treatments over injections in the following situations:

• Symptoms return within a few weeks after each epidural steroid injection.
• Pain occurs consistently at a specific level in the spinal canal, indicating a mechanical problem rather than generalized inflammation.
• Patients experience ongoing functional limitations, such as difficulty sitting, standing, or walking.
• Imaging shows healthy surrounding spinal levels, which is an important requirement for an ADR surgery.

Can a Herniated Disc Limit the Effectiveness of Epidural Injections?

Yes, a herniated disc can limit the effectiveness of epidural injections. While injections reduce inflammation around the irritated nerve, they do not remove the displaced disc material. As a result, symptoms may improve temporarily, but ongoing mechanical pressure can continue to trigger pain or neurological symptoms.

Moreover, prolonged nerve compression from a herniated disc can lead to sensitization, reducing the effectiveness of anti-inflammatory treatments. Similarly, extruded or sequestered disc fragments outside the disc space can affect epidural injection outcomes. These fragments can limit the medication’s ability to reach the irritated nerve and shorten the overall duration of pain relief.

Do Spinal Injections Affect Spinal Load Distribution?

Yes, spinal injections can affect spinal load distribution by altering muscle activity and tissue integrity around the spine. Over time, these changes can contribute to instability, reduced muscular support, and uneven force transfer across spinal segments. This imbalance may increase the risk of degeneration and structural complications.

In addition, according to a study published in Pain Medicine Journal, epidural steroid injections are associated with a significant reduction in bone mineral density and an increased risk of vertebral fractures. The study included 7,233 patients across eight studies, with a mean age ranging from 49 to 74 years. They received various corticosteroids, including triamcinolone, dexamethasone, and methylprednisolone, with injection frequency ranging from one to multiple sessions. The findings showed that higher steroid doses were associated with greater bone loss, which can weaken spinal structure and reduce load-bearing capacity over time.

Why Do Epidural Steroid Injections Wear Off Quickly?

Steroid medication is gradually absorbed and metabolized by the body, which naturally reduces its anti-inflammatory effect over time. In many patients, this process occurs faster than expected due to factors like overall health, individual metabolism, activity level, and the severity of the underlying spinal condition. For example, a study published in Archives of Physical Medicine and Rehabilitation found that out of 140 participants, 32% experienced pain relief after epidural steroid injection that lasted for more than 2 months. In contrast, 39% experienced relief for less than two months, and 29% reported no relief at all.

Besides individual patient factors, ongoing spinal irritation from degenerative conditions can lead to recurrent inflammation, reducing the injection’s effects. In severe cases, anatomical changes such as disc bulging can also prevent the medication from spreading evenly throughout the affected nerve. As a result, the steroid may not reach the inflamed area effectively.

How Many Failed Epidural Injections Are Enough Before Disc Replacement?

Most spine specialists consider disc replacement when 2 to 3 epidural injections fail to improve mobility and pain within a three to six-month period. In fact, if a single injection provides no relief or only lasts a few weeks, they usually avoid administering a second injection and reassess the condition to determine a more effective treatment.

What Are the Risks of Repeated Epidural Steroid Injections?

Repeated epidural steroid injections can cause bone density loss (osteoporosis), weakened muscle and connective tissues, and potential nerve injury. As the medication is absorbed systemically, it can also increase blood sugar levels and blood pressure. In some cases, repeated steroid exposure can suppress immune function, which can cause infections, delay tissue healing, and prolong recovery from disc injuries.

Here are some additional risks of repeated epidural steroid injections:

• Hormonal imbalance (HPA axis suppression): Repeated steroid exposure can disrupt normal cortisol production, which affects the body’s stress response and metabolic regulation.
• Adrenal suppression: The body may reduce its natural steroid production, which can lead to fatigue, weakness, and reduced tolerance to physical stress.
• Fluid retention and weight changes: Systemic steroid absorption can alter fluid balance, leading to swelling or weight fluctuations.
• Risk of dural puncture complications: Although uncommon, repeated injections increase the chance of complications such as spinal headaches due to dural irritation.
• Cartilage and joint impact: Steroids may affect cartilage health over time, which can contribute to joint-related issues beyond the spine.

In fact, a study published in the Global Spine Journal found that steroid injections for lumbar disc herniation were associated with a 2.5% complication rate within 7 days, which increased to 8.8% within 30 days. The most common complications included neurological injury such as paresthesias, cardiac rhythm disturbances (dysrhythmias), and urinary tract infections. Additionally, patients also experienced increased pain, heart-related issues such as heart failure, and emergency department visits.

What Happens If a Spinal Injection Is Given at the Wrong Level?

If a spinal injection is delivered at the wrong level, it will not target the actual source of pain, which leads to little or no symptom relief. This result can mislead diagnosis, delay appropriate treatment, and may cause temporary discomfort at the injected site. Although serious complications are uncommon, you may still experience localized soreness, irritation, or short-term nerve symptoms after the procedure. To avoid such risks, doctors usually use fluoroscopic guidance to confirm the correct spinal level and ensure accurate needle placement during the injection.

What Precautions Should You Take After an Epidural Injection?

After an epidural injection, you should rest for at least the first 24 hours, avoid lifting objects over 10 lbs, and limit strenuous activity for 48 hours to reduce spinal stress. You should also avoid driving, alcohol, and hot tubs for 24 to 48 hours. Here are some additional precautions you must follow after steroid injections:

• Monitor increasing pain, fever, weakness, or loss of sensation, and report these signs promptly.
• Keep the injection site clean and dry to reduce the risk of infection.
• Stay hydrated and maintain light movement, such as short walks, to support circulation.
• Avoid sudden twisting or jerky movements that can irritate the treated area.
• Apply ice packs to the injection site for 15 to 20 minutes at a time during the first 48 hours to reduce swelling and discomfort.
• Attend all follow-up appointments so your doctor can assess your response to the injection.

How Long After a Steroid Injection Can Surgery Be Performed?

After steroid injections, doctors usually wait at least three to six months before performing disc replacement to reduce the risk of postoperative complications. According to Global Spine Journal, about 2.5% of patients who underwent lumbar spine surgery within one month of a steroid injection experienced postoperative infection. On the other hand, only 1.2% of patients who did not receive recent steroid injections experienced these complications.

However, in certain cases, surgeons may proceed with minimally invasive surgery after a shorter interval of 1 to 2 months after an injection. This approach is typically considered when a patient develops a severe neurological deficit that could progress to permanent nerve damage if not treated promptly.

Do You Need An MRI, CT, Or X-Ray Before Disc Replacement?

Yes, imaging such as MRI, CT, or X-ray is required before disc replacement to confirm that you are an eligible candidate for the procedure. These studies help surgeons identify the exact source of symptoms and assess whether the affected spinal level can safely support an artificial spinal disc. Here is how these diagnostic tests help orthopedists determine surgical eligibility:

• MRI examines soft tissues, including the intervertebral disc, spinal cord, and nearby nerves. This allows surgeons to identify the exact level of herniated disc and the extent of nerve compression.
• CT scans visualize bone structure, helping assess whether the vertebral endplates are strong enough to support the implant. They also detect bone spurs or calcified discs that may complicate surgery.
• CT discograms help confirm whether a specific disc is the actual source of chronic pain. During this test, contrast dye is injected into the disc, and imaging is performed to assess its internal structure.
• X-rays, including flexion-extension views, analyze spinal alignment and movement. These assessments help ensure the spine is stable enough to support a successful disc replacement.

Why Surgeons Order Flexion/Extension X-rays Before Disc Replacement?

Orthopedic surgeons use flexion and extension X-rays to assess spinal stability and motion before disc replacement. These dynamic images reveal vertebral motion under load, helping identify abnormal motion patterns and segmental instability. They also help detect conditions like spondylolisthesis that may affect implant performance and surgical planning.

How Do Doctors Reduce the Risk of Complications During Disc Replacement?

To reduce complications during surgery, Dr. Georgiy Brusovanik at Total Orthopedics and Sports Medicine uses minimally invasive techniques, monitors nerve function, and maintains accurate implant positioning with advanced imaging, such as fluoroscopy. With trusted recognition among both local and international patients, he also follows strict sterile protocols to minimize the risk of infection.

Can Lateral Recess Stenosis Affect the Outcome of Disc Replacement?

Yes, lateral recess stenosis can affect the outcome of disc replacement as it narrows the space around the nerve roots. Although disc replacement restores disc height and preserves motion, it may not fully relieve compression caused by bony narrowing. As a result, you may continue to experience persistent leg pain, numbness, tingling, or weakness despite surgery.

To avoid post-surgical complications, surgeons first address the lateral recess stenosis. They perform targeted decompression procedures, such as foraminotomy or partial bone removal, to relieve pressure on the affected nerve roots. Then, they proceed with disc replacement to restore disc height, preserve spinal motion, and improve overall segment function without ongoing nerve compression.

However, in many cases, lateral recess stenosis results from arthritic enlargement of the facet joints (facet hypertrophy). If this condition is present, total disc replacement may not be appropriate due to structural damage in facet joints. In such situations, preserving motion can worsen pain, as the degenerated facets cannot tolerate normal joint movement. Therefore, surgeons prefer spinal fusion, which stabilizes the segment and reduces stress on the affected facet joints.

What Are The Benefits Of Disc Replacement Over Repeated Injections?

Disc replacement addresses the structural source of pain and offers long-term relief, whereas injections only provide temporary inflammation control. Unlike injections, the surgery also restores disc height, relieves nerve compression, and preserves motion at the treated level, providing mechanical stability. Here are some other advantages of disc replacement over steroid injections:

• Avoids repeated exposure to corticosteroids and their side effects
• Limits the need for ongoing imaging and reassessment after each failed injection
• Allows patients to perform daily activities without relying on injections for short-term relief

Quick Tip: Maintain good posture and core strength after surgical recovery to ensure proper spinal support and avoid the need for additional treatments.
