How Do You Know If You Need Lumbar Disc Replacement?

You may need a lumbar disc replacement if you have chronic lower back pain caused by a damaged or worn lumbar disc (L4-L5, L5-S1) that has not improved with nonsurgical treatments. You may also require surgical treatment if you have confirmed single or two-level degenerative disc disease on MRI scans.

In such cases, our minimally invasive spine surgeon, Dr. Georgiy Brusovanik, MD, at Total Orthopedics and Sports Medicine, reviews your imaging results and performs a detailed physical assessment to determine your ADR eligibility. He also evaluates your spinal stability, nerve involvement, and overall health to determine if surgery is appropriate for your condition. Call us today at 855-321-6784 for immediate medical attention in Manhattan.

When Do You Need Lumbar Disc Replacement Surgery?

If you have severe lower back pain that persists for more than 6 months and has not improved with conservative LADR surgeon treatments like NSAIDs or injections, you may need artificial disc replacement surgery. Our may also recommend disc replacement if you experience constant pain that worsens with sitting, bending, or lifting. In more severe cases, if you notice loss of bladder or bowel control, it may indicate Cauda Equina Syndrome, requiring immediate surgical intervention. Without treatment, back pain can worsen over time and may lead to the following long-term spinal conditions:

Chronic Nerve Compression

If you delay treatment, ongoing pressure on spinal nerves can lead to long-term nerve compression or pinched nerves. You may experience constant back and leg pain that does not improve with rest and other non-surgical treatments. In addition, numbness and tingling can become more frequent and intense. You may also notice reduced sensation in certain body parts, such as:

• Lower back and lumbar region
• Buttocks and hips
• Back of the thighs (sciatic nerve area)
• Calves and lower legs
• Feet, especially the soles or toes

Spinal Instability and Deformity

If your disc continues to degenerate, the vertebrae above and below it lose stability. This instability can lead to abnormal movement in your spine, worsening low back pain. Without treatment, your spine may begin to curve or deform abnormally. This deformity can increase uneven pressure on spinal joints and speed up disc degeneration.

In such cases, you may notice the following postural changes:

• Forward-leaning posture (difficulty standing upright)
• Uneven hips or pelvic tilt
• One shoulder appears slightly higher than the other
• Reduced natural curve in the lower back
• Visible shift in body alignment when standing or walking

Lumbar Radiculopathy

If you delay treatment, disc damage can press directly on spinal nerve roots. You may develop lumbar radiculopathy (pain travels from your lower back into one leg). You may also feel sharp, shooting pain that worsens with bending, sitting, coughing, or sudden movement. In some cases, you may notice tingling, numbness, or weakness in the affected leg, which can make walking and daily activities difficult.

Degenerative Disc Disease Progression

Untreated disc damage can continue to worsen over time. Moreover, the affected disc may lose height and hydration, reducing its ability to absorb shock. You may also notice increased stiffness and reduced flexibility in your lower spine. In these cases, disc replacement can help restore disc height, maintain natural spine movement, and reduce pressure on nearby nerves.

Sciatica

If disc degeneration or a herniated disc compresses the sciatic nerve, you may develop sciatica. In fact, according to NCBI, in almost 90% of cases, sciatica is caused by a disc herniation. In this condition, you feel pain that starts in your lower back and passes through your buttocks and down one leg. You may also notice burning or excruciating pain that worsens with sitting, bending, coughing, or lifting.

Segmental Instability in the Lumbar Spine

In this condition, one or more vertebral segments in your lower spine move abnormally due to weakened discs and ligaments. You may experience recurring lower back pain that worsens with movement, bending, or lifting. Moreover, the pain can feel like a deep ache with occasional pain flare-ups during activity. According to the Spine Health Foundation, you may also experience stiffness in the back, muscle spasms, and a sensation that your back is “giving out.”

What Tests Help Confirm the Need for Disc Replacement?

To confirm if you need ADR, our spine surgeon, Dr. Georgiy Brusovanik, MD, may order MRI (magnetic resonance imaging) and X-rays (including flexion-extension views). In some cases, he may also recommend EMG (electromyography) and discography to confirm your eligibility for ADR spinal surgery. Here’s how these tests help identify the exact source of pain and determine if you are a good candidate for disc replacement:

MRI

MRI clearly shows detailed images of your spinal discs, nerves, and surrounding soft tissues. It also helps identify disc degeneration, bulging, or herniation that may be causing your back pain. This clear visualization allows our surgeon to match your L5–S1 or L4-L5 disc symptoms to the exact level of damage in your spine.

X-Rays

X-rays provide clear images of your spinal alignment and bone structure. They help detect disc space narrowing, which may indicate disc damage at levels like L4–L5 or L5–S1. Here are different types of X-rays that can help diagnose spinal conditions accurately:

• Standard (Static) X-rays: Show overall spinal alignment and disc space height
• Flexion X-rays: Taken while bending forward to assess forward movement
• Extension X-rays: Taken while bending backward to evaluate backward motion
• Flexion-Extension Views: Compare movement between different positions to detect instability
• AP and Lateral Views: Show front and side angles of the spine to assess alignment and disc height

Discography

During the discography test, a contrast dye is injected into your disc. If the injected disc causes pain, it confirms that this level is the source of your symptoms. Moreover, this diagnostic testing dye helps our surgeon clearly identify whether the problem is at L4–L5 or L5–S1. It also helps assess the disc’s internal structure, including cracks or tears in the outer layer.

EMG (Electromyography)

Our spine specialist may use electromyography (EMG) to assess nerve function and identify the source of pain, weakness, or numbness. EMG measures the electrical activity in your muscles to detect abnormal signals caused by nerve irritation or compression. Additionally, according to Frontiers, researchers used surface EMG to identify nerve-root compression in lumbar disc herniation. The study showed 84% diagnostic accuracy with an AUC of 0.93.

Here are some additional types of EMG studies that can help identify spinal disorders:

• Needle EMG: Detects nerve root damage by measuring muscle electrical activity directly.
• Nerve Conduction Studies (NCS): Evaluates how fast electrical signals pass through peripheral nerves affected by spinal compression.
• Radiculopathy EMG testing: Focuses on specific spinal levels (L4, L5, S1) to locate exact nerve root irritation or damage.

In addition to imaging tests, Dr. Georgiy Brusovanik performs physical exams to assess your condition. These tests may include the Straight Leg Raise (SLR) test to check for nerve irritation and the Femoral Nerve Stretch test to evaluate upper lumbar nerve involvement. He may also perform a neurological exam to assess reflexes, muscle strength, and sensation. In our experience, we have noticed that combining these physical findings with your symptoms helps accurately determine if you are a suitable candidate for ADR. Call 855-321-6784 to schedule your consultation.

Which Conditions Are Treated With Disc Replacement Surgery?

Our spine specialist, Dr. Georgiy Brusovanik, recommends ADR for lumbar degenerative disc disease, discogenic low back pain, and disc herniation. Loss of disc height, sciatica, and bulging discs can also be treated with artificial disc replacement surgery. Similarly, ADR may be recommended for annular tears (small cracks in the disc wall) and mechanical back pain caused by a single damaged disc.

A study published in World Neurosurgery assessed 11 professional athletes who underwent lumbar disc replacement and reported significant pain reductions. The athletes also reported maintaining normal motion at L4–L5 or L5–S1 and returning to sports after 9.7 weeks. However, before undergoing ADR, you must meet certain eligibility criteria, including:

Stable Spine Alignment

You should not have significant spinal instability or structural deformity before undergoing ADR. Spinal conditions such as spondylolisthesis <Grade I, segmental instability, or severe scoliosis may not support the artificial implant. In these cases, our surgeon may recommend other surgical alternatives to protect your spine and reduce the risk of the following implant complications:

• Implant shifting or displacement
• Uneven load on the artificial disc
• Increased implant wear over time
• Reduced function of the artificial disc

Normal Disc Height

To safely undergo ADR, you should have adequate disc height, usually more than 4 mm. This height allows the artificial disc to fit accurately and preserve normal spinal motion. However, if the disc space is severely collapsed, the implant may not fit properly. In such cases, ADR may not restore normal disc height, potentially affecting surgical outcomes. You may also experience increased pressure on nearby joints due to reduced spacing, leading to ongoing lower back pain.

Healthy Body Weight

Excess weight places additional stress on the artificial disc after the surgical procedure. This extra weight can also speed up the disc wear and shorten the implant lifespan. In these cases, Dr. Georgiy Brusovanik often recommends the following targeted weight management strategies to protect your spinal health:

• Follow a calorie-controlled diet: Focus on reducing daily calorie intake through measured portions and balanced meals to prevent weight gain.
• Increase low-impact aerobic activity: Walk 30–45 minutes daily or use a stationary bike to reduce body fat.
• Strengthen core muscles safely: Perform guided exercises like pelvic tilts and gentle abdominal activation to support the lower spine.
• Limit prolonged sitting: Stand or walk every 30–45 minutes to reduce pressure on the lumbar spine and artificial disc.

Adequate Bone Health

Your bone density must be strong enough for L4–L5 or L5-S1 disc replacement surgery. If your bones are weak, the artificial disc may not stay properly secured, leading to implant loosening. Once your implant loosens, you may experience persistent or worsening back pain, reduced spinal cord stability, and abnormal movement at the treated level. Therefore, our doctor may order a bone density test to evaluate your bone strength and determine if your spine can safely support the implant.

How Does Facet Joint Health Affect LADR Success?

If you have healthy facet joints, they can properly support and guide spinal movement after lumbar artificial disc replacement (LADR). These joints work together with the spinal disc to control bending, twisting, and extension of your lower spine, especially at L4–L5 and L5–S1 levels. When the facet joints are in good condition, the artificial disc can function more naturally, providing smooth motion without abnormal friction.

In addition, healthy facet joints help distribute mechanical load evenly across the spinal segment. This load distribution reduces excessive stress on the implant and prevents uneven pressure on surrounding structures. However, if your facet joints are damaged or degenerated, they can reduce the success of LADR. Worn joints may also continue to cause lower back pain and spinal canal instability, even after the procedure. For this reason, evaluating facet joint health before surgery is essential to ensure better outcomes and long-term relief.

What Pre-Surgery Lifestyle Changes Improve ADR Results?

Before ADR, you should maintain a healthy body weight, stay physically active, and quit smoking to improve surgical outcomes. You should also improve posture habits and manage any chronic medical conditions to support better surgical outcomes. Other than that, strengthen your core muscles and manage any existing health conditions, such as diabetes or hypertension, before surgery.

Moreover, follow a balanced diet rich in protein, vitamins, and minerals to support tissue repair after the procedure. Here’s how these lifestyle changes can help you improve ADR surgical outcomes and protect your spinal health:

• Quitting Smoking: Enhances blood circulation and oxygen delivery, which supports tissue healing and lowers the risk of implant-related complications.
• Core Strengthening: Stabilizes the spine by supporting surrounding structures, reducing strain on the artificial disc during movement.
• Posture Correction: Maintains proper spinal alignment, preventing uneven load distribution on the implant and adjacent segments.
• Nutritional Support: Provides essential nutrients like protein, calcium, and vitamin D that aid tissue repair and maintain bone health.
• Chronic Condition Management: Helps control diabetes, hypertension, or other conditions, improving recovery and reducing surgical risks.

Our spine surgeon, Dr. Georgiy Brusovanik, guides each patient through these lifestyle changes step by step before surgery. He carefully evaluates your spine condition and helps prepare your body for the best ADR outcome, ensuring safe surgery and a smooth recovery. To make your treatment easier, our team also accepts a wide range of insurance plans and helps you verify your coverage before surgery. If you don’t have insurance coverage, we offer clear self-pay pricing and flexible payment options to make treatment more accessible. Call us at 855-321-6784 to book your appointment.

What Are the Benefits of Motion Preservation Surgery?

Motion preservation surgery, such as ADR (Artificial Disc Replacement), helps maintain natural spine movement while reducing pain and improving spinal function. By replacing the damaged disc, ADR also preserves flexibility at the treated level, allowing you to bend, twist, and move more naturally compared to fusion surgery.

By maintaining natural motion, ADR also distributes mechanical load evenly across your spine. This balance protects nearby joints and discs from early degeneration. Moreover, you experience smoother movement, better posture, and long-term pain relief. Here are some additional benefits of artificial disc replacement:

• Minimized Postural Imbalance: By restoring disc height and motion, ADR helps maintain proper spinal alignment, reducing strain on muscles and joints.
• Enhanced Daily Function: Supports easier performance of routine activities like sitting, standing, and walking.
• Reduced Muscle Strain: Minimizes compensatory muscle overuse around the spine, improving comfort during movement.
• Faster Return to Activity: Helps you resume normal physical activities with better mobility and less stiffness.

Can Disc Surgery Reduce the Chances of Future Spine Problems?

Yes, artificial disc replacement (ADR) can reduce the risk of certain future spinal issues. This procedure replaces the damaged disc entirely while preserving natural movement at the affected level. Because of this, ADR also helps prevent “Adjacent Segment Disease” (ASD) (a condition where discs degenerate over time). Besides that, ADR supports long-term spinal function by maintaining natural biomechanics, helping you move with improved flexibility.
