Can Dr. Georgiy Brusovanik Do Disc Replacement After a Failed Fusion?

Yes, Dr. Georgiy Brusovanik, MD, at Total Orthopedics and Sports Medicine, performs minimally invasive surgeries, such as disc replacement after a failed fusion. However, before recommending this procedure, he conducts a detailed physical examination and orders advanced imaging to assess bone quality, disc height, facet joint health, and prior surgical changes. This assessment helps him identify the exact cause of your symptoms and determine your eligibility for revision disc replacement.

Then, he uses advanced surgical techniques to remove old fusion hardware, clear scar tissue, and implant an artificial disc through an anterior approach. During the procedure, he also uses real-time imaging guidance to ensure accurate implant placement and protect surrounding nerves. Call us at 855-321-6784 to consult Dr. Georgiy Brusovanik.

How Is Revision Disc Replacement Performed After A Prior Lumbar Fusion?

Our spine specialists perform disc replacement through an anterior (front of the spine) incision, which helps us avoid prior posterior scar tissue. Then, we remove the hardware from the failed fusion and prepare the disc space by releasing the anterior longitudinal ligament. If you are experiencing adjacent segment disease, we also remove the degenerated disc at that level before placing the artificial implant.

After preparing the disc space, we insert the artificial disc using specialized instruments to position it precisely between the vertebrae. Then, we confirm the disc’s placement using real-time imaging to ensure correct alignment and secure contact with the bone. To minimize surgical complications, we perform this entire procedure with careful tissue handling and minimally invasive techniques. We also closely monitor nerve function throughout the operation to prevent nerve injury.  

According to a study published in the Journal of Neurosurgery, 20 patients who underwent lumbar disc replacement for adjacent-segment degeneration after prior fusion showed significant improvement in ongoing pain and disability at two years, with 86% satisfaction and no reoperations. 

Does Dr. Georgiy Brusovanik Offer Hybrid Reconstruction After Failed Fusion?

Yes, Dr. Georgiy Brusovanik, our minimally invasive spine surgeon, offers hybrid reconstruction after failed fusion. In this procedure, he performs disc replacement at one level and revises the fusion at the previously treated level. This approach helps preserve motion at the degenerated adjacent level while stabilizing the failed or unstable fusion segment. He usually recommends this procedure when a failed fusion leads to degeneration at adjacent levels, but cannot be converted into disc replacement due to:

• Severe facet joint damage
• Solid fusion of vertebrae
• Poor bone quality or weak vertebral support
• Significant spinal instability
• Structural changes from prior surgery that limit safe implant placement

What Are the Warning Signs of Failed Lumbar Fusion?

A failed lumbar fusion may cause persistent or worsening pain in the back, buttocks, and legs after surgery. In many cases, it also leads to neurological symptoms like numbness, tingling, and radiating discomfort, which indicate nerve root irritation. Other than that, a failed lumbar fusion may cause a reduced range of motion that does not improve with targeted exercises. 

Some other signs of a failed lumbar fusion include: 

• Foot drop 
• A noticeable bulge or deformity at the surgical site
• Popping or grinding sensation 
• Muscle spasms in the back
• Infection symptoms like fever, chills, redness, and warmth 

At Total Orthopedics and Sports Medicine, Dr. Georgiy Brusovanik schedules regular follow-up appointments to closely monitor recovery. During these visits, he performs a detailed physical examination and orders imaging tests to detect complications early. If he identifies any problem, he develops a targeted plan that may include conservative treatment options, such as rehabilitation adjustments, image-guided spinal injections, and nerve-modulating medications. In some cases, he may also consider revision procedures such as lumbar total disc replacement to address spinal instability.

Can a Spinal Infection Be Misdiagnosed as a Failed Lumbar Fusion?

Yes, a spinal infection can be misdiagnosed as a failed lumbar fusion. Both conditions cause similar symptoms, especially chronic lower back pain at the surgical site that may appear months or even years after initial surgery. They also lead to inflammation, stiffness, and nerve-related symptoms such as leg pain or numbness.

Even during imaging review, the diagnosis can remain unclear as metal implants such as screws and rods often create visual distortions on MRI and CT scans. These distortions can mask signs of infection or make it difficult to distinguish infection from hematoma or normal bone healing, increasing the risk of misdiagnosis.

To identify spinal infections accurately, revision lumbar disc replacement surgeons may use the following methods:

CRP and ESR

Doctors track C-Reactive Protein (CRP) and Erythrocyte Sedimentation Rate (ESR) after surgery. If these markers are elevated beyond the 10 to 15-day recovery period, they indicate infection rather than a failed fusion.

18F-FDG-PET Scans

If MRI or CT scans fail to provide clear results, surgeons use 18F-FDG PET scans. These scans detect increased metabolic activity in infected tissue, which helps identify infection and distinguish it from normal healing or degenerative changes. For example, according to the Journal of Orthopedic Surgery and Research, 18-FDG PET scans can detect pyogenic spinal infection (spondylodiscitis) with a sensitivity of up to 95%.

CT-Guided Aspiration or Biopsy

In some cases, surgeons perform CT-guided aspiration or biopsy to collect tissue or fluid from the affected area. This sample is then analyzed in the laboratory to identify bacterial growth and confirm infection. The results also help guide targeted antibiotic therapy for more effective and precise treatment.

Observe Clinical Symptoms

According to the American Association of Neurological Surgeons, spine infections such as vertebral osteomyelitis may cause fever, chills, weight loss, and muscle spasms. Based on these potential signs, doctors monitor your symptoms to detect possible infection. These symptoms are often accompanied by persistent pain that does not improve or progressively worsens over time.

What’s the Difference Between Pseudarthrosis and Adjacent Level Disease?

Pseudarthrosis, or a false joint, refers to the failure of vertebrae to fuse at the operated level after spinal fusion surgery. In contrast, adjacent segment disease involves progressive degeneration at levels above or below a previously fused segment. To confirm pseudarthrosis, surgeons order CT scans that show incomplete bone fusion, hardware loosening, or the absence of solid bone bridging. However, to identify adjacent segment degeneration, they rely on MRI and X-rays to detect disc degeneration, nerve compression, or spinal cord pressure at nearby levels.

In addition, pseudarthrosis usually causes persistent localized back pain and mechanical instability. On the other hand, adjacent-segment disease is more frequently associated with the following nerve-related symptoms when degenerated discs compress nearby nerve roots:

• Radiating pain down the legs (sciatica)
• Numbness or tingling in the legs or feet
• Muscle weakness in the lower extremities
• Difficulty walking or maintaining balance
• Reduced reflexes in the knees or ankles

Similarly, pseudarthrosis is commonly associated with factors that impair bone healing, such as smoking, low bone density, or poor surgical fixation. On the other hand, adjacent segment disease results from increased mechanical stress on nearby levels after fusion. To address pseudarthrosis, doctors commonly perform revision fusion surgery. During this surgery, they stabilize the segment again using additional hardware and bone grafts to achieve proper fusion. In contrast, treatment for adjacent segment disease may involve decompression surgery or extension of the fusion to the affected levels or, in selected cases, disc replacement to preserve motion.

Can Bone Density Affect Your Eligibility for Revision Disc Replacement?

Yes, bone density can affect your eligibility for minimally invasive spine surgery such as revision disc replacement. If you have severe osteoporosis or osteopenia, surgeons may not recommend the procedure, as weakened vertebrae cannot securely support the implant. In such cases, the implant can sink into the vertebral body, which may lead to persistent back and leg pain and mechanical failure. 

According to a study published in ScienceDirect, patients with significantly low bone mineral density (BMD) (2 standard deviations below the average) have a high risk of implant subsidence. In contrast, those with mild to moderate bone loss (1.5 standard deviations below the average) may safely undergo disc replacement with careful surgical planning.

To treat weak bones, our lumbar artificial disc surgeon first treats the underlying osteoporosis with bone-strengthening medications and calcium and vitamin D supplementation. If your bone density does not improve despite treatment, we may consider alternative procedures such as augmented spinal fusion to stabilize the affected spinal level.

How Does Prior Bone Growth Affect Revision LDR?

Prior bone growth from a previous fusion can limit access to the disc space, making it difficult for surgeons to safely place the implant during revision LDR. It can also interfere with the stable fixation of the artificial disc by altering the normal shape of the vertebral endplates. This increases the risk of complications such as aseptic loosening or implant migration, which can affect long-term stability and outcomes.

In fact, according to BMC Musculoskeletal Disorders, severe bone growth can completely restrict spinal motion and lead to unintended fusion. Since lumbar disc replacement depends on preserving motion, this may limit your eligibility for lumbar disc replacement.

How Orthopedic Specialists Address Prior Bone Growth?

Before performing lumbar disc replacement, surgeons order MRI and CT scans to identify bone overgrowth, such as osteophytes, and plan precise surgical removal of excess bone. During surgery, they carefully prepare the adjacent vertebrae by removing overgrowth and reshaping the endplates to support stable implant placement. They also use advanced intraoperative imaging to confirm complete bone removal and accurately position the artificial disc.

Is Hardware Removal Necessary Before Revision Disc Replacement?

Yes, hardware removal is often necessary before revision disc replacement if it blocks access to the disc space or interferes with proper implant placement. In such cases, our top-rated spine surgeon specialists conduct detailed imaging to confirm whether hardware removal is required and plan the procedure precisely.

Then, we use advanced surgical techniques to access the fused vertebra and remove screws or rods carefully to avoid unnecessary bone loss or nerve irritation. We also ensure hardware removal does not destabilize the spine and affect the surgical outcomes of the revision disc replacement. 

What Are the Risks of Revision Disc Replacement After Fusion?

Common risks of revision disc replacement include implant migration, heterotopic ossification (abnormal bone growth), and implant subsidence. In some cases, infection may also occur due to prior surgical exposure and tissue disruption, which can delay healing. Additionally, revision disc replacement after failed spine surgery may cause:

• Vascular injury: Damage to nearby blood vessels, especially during the anterior approach
• Nerve injury: Irritation or damage to nerve roots, which may cause leg pain or numbness
• Adjacent level stress: Increased load on nearby segments may lead to degeneration at the surrounding disc levels
• Reduced range of motion: The implant may fail to restore the expected spinal movement
• Dural tear: A tear in the spinal membrane can occur during disc space exposure, leading to leakage of spinal fluid and symptoms such as headaches or nausea

Are There Any Activity Restrictions After Revision Disc Replacement?

Yes, you must follow specific activity restrictions after revision disc replacement surgery. You should avoid bending, lifting heavy objects, driving, or twisting your torso excessively during the initial recovery period. You must also avoid high-impact activities such as running, contact sports, and horseback riding.  

Here are some additional activity restriction guidelines you must follow after revision disc replacement:

• Limit sitting for prolonged periods or stair climbing, especially during the first few weeks
• Avoid sudden direction changes while walking
• Do not perform stretching exercises that strain the lower back
• Avoid walking on uneven surfaces that can affect balance and posture
• Avoid lifting objects above shoulder level or reaching overhead while holding weight

How Long Does It Take to Recover After Revision Disc Replacement?

Recovery after revision lumbar disc replacement typically takes about 3 to 6 months, although early healing begins within the first 1 to 2 weeks. In most cases, you can return to light, sedentary activities between three and six weeks. Here are some common factors that may affect your overall recovery duration:

• Number of spinal levels treated
• Bone quality and spinal stability
• Presence of nerve compression before surgery
• Your age and baseline fitness level
• Ability to follow targeted exercise programs

To speed up recovery, our orthopedic revision surgeons develop a structured recovery program. This program includes pain management strategies, strengthening exercises, mobility training, and spine-protecting techniques for daily activities. This program progresses in phases to align your healing stage and prevent overloading the surgical site. It also focuses on restoring core stability and improving movement patterns during daily activities to reduce stress on the healing spine.
