How Does Dr. Georgiy Brusovanik Preserve Motion at the L4 L5 Segment?

Dr. Georgiy Brusovanik preserves motion at the L4–L5 segment by performing lumbar disc replacement (LDR) surgery instead of spinal fusion. Unlike spinal fusion, LDR replaces the damaged disc without permanently limiting motion, supporting natural movement in the lower back.

At Total Orthopedics & Sports Medicine, Dr. Georgiy Brusovanik, MD, provides advanced motion-preserving surgical treatment for L4–L5 disc degeneration. During your consultation, he carefully assesses your symptoms, confirms the diagnosis with imaging, and determines whether lumbar disc replacement surgery aligns with your activity goals. Call 855-321-6784 to schedule a consultation with our lumbar arthroplasty specialist.

How Does L4–L5 Motion Preservation Surgery Work?

During L4–L5 motion-preservation surgery, Dr. Georgiy Brusovanik approaches the disc through an anterior incision in the front of the abdomen. This approach allows clear visualization of the disc space during the procedure while protecting the major lower back muscles. After accessing the disc, he removes the damaged disc and places an artificial disc in its position.

Throughout the procedure, our medical team carefully monitors nerve function in real time to support surgical safety. Once the artificial disc is positioned and stabilized, our spine specialist uses imaging guidance to confirm accurate alignment before closing the incision. After surgery, we also guide patients through the postoperative recovery phase, including activity recommendations. For example, a clinical case report of a 52-year-old man who underwent total disc replacement for degenerative disc disease reports how postoperative care supports recovery. He had experienced severe back pain for several years despite conservative care.

To restore motion at the spinal segment, doctors performed lumbar disc replacement at the affected L5–S1 level. Six weeks after surgery, the patient began an eight-week rehabilitation program focused on motor control and strengthening exercises. After completing the rehabilitation program, follow-up assessments showed significant improvements in pain and daily function. Imaging tests also showed increased muscle activity around the treated segment.

Is Lower Back Pain at L4–L5 Always a Disc Problem?

No, lower back pain at the L4–L5 level is not always caused by a damaged disc. Several other conditions, including spinal stenosis, muscle strain, and ligament thickening around the lumbar spine, can also produce similar symptoms. Each of these conditions can place pressure on nearby nerves in the spinal canal. This pressure may cause chronic pain that spreads from the lower back to the legs. However, a careful diagnosis helps determine whether the symptoms are due to disc degeneration or another spinal condition.

Here is how our surgeons differentiate these conditions from L4–L5 disc problems:

Pinched Nerve

To determine whether your symptoms are caused by a pinched nerve or L4–L5 disc problem, we begin with a focused physical examination to check for signs of nerve damage. During the exam, tests such as the straight-leg raise may reproduce tingling, numbness, or radiating leg pain. These findings can signal irritation of the lumbar nerve roots. We then review your CT scan or magnetic resonance imaging to identify the source of the pinched nerve.

Facet Joint Arthritis

Facet joint arthritis often causes lower back pain that worsens when you lean backward or rotate your spine. These movements place additional stress on the small joints located at the back of the vertebrae. During the examination, we assess how your pain responds to these motions and check for tenderness around the affected joints. Our spine surgeon then reviews your MRI or CT scan imaging to confirm the diagnosis. These scans may show joint enlargement, cartilage degeneration, or small bone spurs around the facet joints that contribute to lower back pain.

Spinal Stenosis

Spinal stenosis causes a different pain pattern than L4–L5 disc-related pain. Symptoms usually worsen when you stand upright or walk for longer distances. However, the discomfort often improves when you lean forward or sit down, which relieves pressure in the spinal canal. During the evaluation, our specialist looks for this posture-related pattern because it commonly indicates spinal stenosis rather than a disc problem. Our specialist also reviews your MRI or CT imaging to determine whether the spinal canal has narrowed.

Muscle Strain

Unlike disc-related pain, muscle strain usually causes localized back pain that does not radiate to the legs. Because the symptoms are localized to the lower back, during the clinical examination, we focus on the muscles along the lumbar spine. We assess these muscles for tenderness, tightness, or localized discomfort that may indicate a soft tissue injury rather than disc degeneration. When necessary, MRI or computed tomography imaging is also reviewed to confirm that the spinal discs and nearby nerves are not compressed. This evaluation helps us distinguish muscular pain from symptoms associated with L4–L5 disc problems.

What Are the Symptoms of L4–L5 Disc Damage?

L4–L5 disc damage often causes lower back discomfort and nerve-related leg symptoms that worsen with movement or prolonged sitting. As the disc degenerates or shifts out of place, nearby nerves can get irritated or compressed, leading to pain patterns that affect both the spine and the lower extremities. These symptoms may develop gradually or appear suddenly after strain or injury.

Here are some other common symptoms of L4–L5 disc damage:

• Muscle spasms: Sudden tightening or cramping in the lower back.
• Radiating Pain (Sciatica): Sharp or burning pain that travels from the lower back into the buttock and down the leg.
• Weakness: Difficulty lifting the foot or maintaining strength while walking.
• Postural changes: Shifting body position to avoid pain, sometimes affecting balance or gait.

How Does L4–L5 Disc Degeneration Affect Everyday Activities?

L4–L5 disc degeneration affects everyday activities by reducing disc height, altering spinal movement, and irritating nearby nerve roots. As the cushioning between the vertebrae decreases, the spinal segment may move less smoothly, placing extra stress on surrounding joints and nerves. This additional stress can lead to pain during everyday movements involving the lower back.

Here are the common daily activities that L4–L5 disc degeneration can affect:

• Sitting for extended periods: You may find it difficult to sit comfortably at work, while driving, or during long meetings.
• Walking or standing: Irritation of nearby nerve roots may cause leg discomfort, fatigue, or radiating pain during prolonged walking or standing. These symptoms can limit mobility and endurance.
• Bending forward: Disc degeneration can reduce flexibility in the lower spine. As a result, movements such as tying shoes or reaching toward the floor may become painful or difficult.
• Lifting everyday objects: A weakened disc absorbs pressure less effectively. Because of this, lifting groceries or household items may trigger lower back pain or muscle strain.

Which Advanced Technologies Do We Use in Lumbar Disc Replacement?

Our spine specialist uses real-time imaging, robotic assistance, and continuous nerve monitoring during lumbar disc replacement surgery. These technologies help identify the correct spinal level, allow accurate implant placement, and reduce the risk of nerve irritation or injury during the procedure.

Here’s how these technologies improve surgical precision:

Robotic Guidance

Before surgery, Dr. Georgiy Brusovanik uses advanced robotic-assisted planning software to analyze your spinal anatomy, determine optimal implant size, and map out the precise placement strategy. This planning helps our minimally invasive spine surgeon select an implant that fits your spinal anatomy and ensures accurate implant placement during minimally invasive lumbar surgery.

Intraoperative Imaging

During lumbar motion-preservation surgery, we use real-time fluoroscopic imaging to confirm the correct spinal level and visually verify implant placement. This allows us to confirm alignment and positioning before completing this minimally invasive spine surgery.

Intraoperative Monitoring of Nerve Function

Our lumbar spine surgeon uses intraoperative nerve monitoring to continuously track nerve function during disc removal and implant placement. If the monitoring system detects changes in nerve signals indicating pressure or irritation, we immediately reposition the instruments or adjust the implant placement to protect the nerve.

Can Motion Preservation Surgery Relieve Lower Back and Sciatica Pain?

Yes, motion preservation surgery can relieve lower back and sciatica pain by reducing pressure on spinal nerves while maintaining movement at the treated level. This pressure often develops when a damaged disc loses height or presses on nearby nerve roots, causing back pain and radiating leg symptoms.

Moreover, a peer-reviewed study published in the Journal of Orthopaedic Surgery and Research reported significant reductions in back and leg pain after motion-preserving disc replacement. These results were consistent over mid- to long-term follow-up, supporting motion preservation as a reliable option for disc-related pain.

What Type of Implants Are Used in L4–L5 Disc Replacement?

In L4–L5 disc replacement, we use advanced artificial discs made from medical-grade titanium, cobalt-chrome alloys, and durable polyethylene. These implants feature two metal endplates and a central core designed to support bending and rotation similar to a healthy, natural disc.

Here are the common characteristics of the implants we use in L4–L5 disc replacement:

• FDA Approved: Approved by the U.S. Food and Drug Administration for lumbar disc replacement surgery.
• Motion Preservation Design: Allows controlled bending and rotation at the treated level instead of permanently fusing the vertebrae.
• Load Distribution: Designed to distribute mechanical forces evenly across the vertebral endplates during daily activities.
• Anatomical Compatibility: Selected based on your spinal anatomy to ensure appropriate fit and stable positioning.

How Do Surgeons Manage Pain After Artificial Disc Replacement Surgery?

Our spine surgeon, Dr. Georgiy Brusovanik, manages pain after artificial disc replacement surgery using targeted medications, anti-inflammatory treatments, and careful postoperative monitoring. This approach helps reduce inflammation, calm irritated nerves, and keep you comfortable while your spine heals. Here’s how these approaches help manage pain after surgery:

Multimodal Pain Medication

To control pain after surgery, Dr. Georgiy Brusovanik may recommend a combination of medications that work together to manage postoperative pain. This approach, called multimodal pain management, helps reduce inflammation, calm irritated nerves, and simultaneously control surgical discomfort. Common medications used are acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), or medications that help control nerve-related pain. In fact, a review published in the Journal of Spine Surgery reported that multimodal analgesia improves postoperative pain control and reduces opioid use after spine surgery.

Early Mobilization

Dr. Georgiy Brusovanik may also encourage early mobilization after minimally invasive lumbar surgery to help manage postoperative discomfort and support recovery. Gentle movement, such as short walks, helps reduce stiffness and prevents the spine from becoming overly rigid during healing. Moreover, according to a review published in Surgical Neurology International, early mobilization after spinal surgery is also associated with lower complication rates and shorter hospital stays, supporting a smoother recovery.

Ice and Heat Therapy

Our surgeon may also recommend ice or heat therapy to help manage discomfort after artificial disc replacement surgery. In the early phase of recovery, applying ice packs to the lower back can help reduce inflammation and provide significant pain relief around the surgical area. As healing progresses, gentle heat therapy may be used to relax surrounding muscles and reduce stiffness in the lumbar spine, which helps you move more comfortably.

Do You Heal Faster With Motion Preservation Compared to Fusion?

Yes, you may recover faster with motion preservation than with fusion because it allows your spine to keep moving naturally during healing, rather than being permanently locked. As a result, you may resume your daily activities within weeks rather than months. Moreover, a five-year study published in NCBI found that 38% of patients who underwent disc replacement were completely pain-free after five years. In comparison, only 15% of patients who underwent fusion surgery were pain-free at the same follow-up point.

At Total Orthopedics & Sports Medicine, we guide your recovery process with carefully planned follow-up visits after surgery. Dr. Georgiy Brusovanik monitors your progress, reviews imaging when needed, and adjusts activity levels based on your healing. Our specialist, who has been featured on CNN and PBS for his expertise in motion-preserving treatments, also provides step-by-step rehabilitation guidance to help you regain strength and mobility while minimizing the risk of reinjury.

Can L4–L5 Disc Degeneration Worsen Without Treatment?

Yes, L4–L5 disc degeneration can worsen without treatment. As the disc gradually loses hydration, height, and structural strength, it provides less cushioning between the vertebrae, disrupting normal lumbar spine movement. Over time, this loss of support can increase mechanical stress on nearby joints and nerve structures, allowing degenerative changes to progress. If left untreated, these changes may also lead to the following conditions:

• Disc bulging or herniation: As the disc weakens, its outer layer may protrude, allowing disc material to push into the spinal canal or nearby nerve spaces. This pressure can irritate spinal nerves, leading to radiating leg pain, or sciatica.
• Spinal canal narrowing (spinal stenosis): Degenerative changes around the disc, including thickened ligaments or bone overgrowth, may gradually reduce the available space inside the spinal canal.
• Formation of bone spurs (osteophytes): As the spine becomes unstable, small bony growths may form along the vertebrae. These bone spurs can narrow the space around nearby nerves, leading to irritation.
• Changes in spinal alignment: Progressive disc degeneration may alter the way vertebrae stack and move, sometimes contributing to segmental instability or abnormal motion at the affected level.

Moreover, a 10-year MRI follow-up study published in Annals of the Rheumatic Diseases examined 234 pairs of twins and measured changes in lumbar discs over time. The investigators found that all MRI features of lumbar disc degeneration worsened significantly during follow-up. These changes included loss of disc height, disc bulging, signal changes within the disc, and anterior osteophyte formation.
