Does Dr. Georgiy Brusovanik Perform Minimally Invasive Lumbar Surgery?

Yes, our spine surgeon, Dr. Georgiy Brusovanik, MD, at Total Orthopedics & Sports Medicine, performs minimally invasive spine surgery to relieve pressure on the affected spinal discs. During the procedure, he carefully makes a small anterior incision to remove the damaged disc tissues, restore disc height, and stabilize the spinal segment. After that, he places an artificial disc to preserve motion in the lumbar spine and reduce stress on nearby segments. This minimally invasive technique minimizes tissue disruption, protects back muscles, and preserves surrounding spinal structures. Call 855-321-6784 to schedule your consultation with our minimally invasive lumbar spine specialist.

What Is the Process for Minimally Invasive Anterior Lumbar Surgery?

During minimally invasive anterior lumbar surgery, our MIS lumbar disc replacement surgeon makes a small incision in the front of your abdomen. This anterior approach allows direct access to the affected lumbar disc while protecting major back muscles and posterior spinal structures. After accessing the disc, we remove any degenerated material that may be compressing the surrounding nerves.

Moreover, our team also uses the following imaging tools throughout minimally invasive spinal surgery (MISS) to improve accuracy and safety:

• Fluoroscopy (real-time X-ray imaging): Guides implant placement during surgery. It also helps confirm the correct spinal level in real time.
• Intraoperative X-rays: Provide detailed images during surgery to verify accurate artificial disc positioning and proper spinal alignment.
• CT-based navigation systems: Advanced 3D imaging to enhance surgical precision and support highly accurate implant placement.

Throughout the surgery, our team carefully monitors the surrounding structures to protect nerves and other tissues. Once the disc and spinal segment are stabilized, our minimally invasive spine surgeon closes the incision and confirms proper alignment to ensure safe and effective results. According to an NCBI study, minimally invasive anterior lumbar surgery showed an average pain reduction of 56%.

Why Is the Anterior Approach Used for Lumbar Spinal Surgery?

The anterior approach in lumbar spine surgery allows us to access the spinal cord through the front of the body, directly reaching the disc space without cutting through major back muscles and soft tissues. This approach also restores disc height, fixes spinal alignment, minimizes pain, and speeds recovery.

Additionally, a Clinical Spine Surgery review of 122 patients compared anterior surgery with posterolateral fusion. The study found that anterior fusion resulted in significantly less blood loss and shorter operative time compared to the posterior approach. Here are some additional benefits of the anterior approach during spine surgery:

Direct Access to the Disc Space

The anterior approach provides direct access to the disc space. This allows clear visualization of the spinal column, which helps our lumbar disc replacement surgeon remove diseased disc material with more precision. It also supports accurate implant placement during minimally invasive surgery.

Improved Implant Sizing

Larger and more stable implants can be placed through the anterior approach. These implants are designed to cover a wider surface area of the vertebral endplates. Because of this, weight is distributed more evenly across the spine, improving overall spinal stability. In addition, better load distribution lowers the risk of implant subsidence or displacement over time.

Lower Risk of Nerve Root Retraction

The anterior approach limits direct contact with spinal nerves during the procedure. Surgeons access the disc space from the front, which avoids extensive nerve retraction. This approach lowers the chances of irritation or injury to the nerve roots. It also helps reduce postoperative symptoms such as:

• Numbness or tingling in the lower extremities
• Constant pain radiating into the legs
• Muscle weakness affecting mobility and stability
• Sensory changes linked to spinal cord compression

What Blood Tests Are Required Before Lumbar Disc Replacement Surgery?

Before lumbar disc replacement surgery, you typically undergo a Complete Blood Count (CBC) test to check for anemia or infection, and a Basic Metabolic Panel (BMP) to assess kidney function and electrolyte levels. In some cases, your doctor may order inflammatory markers such as C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) to detect any underlying infection or inflammation. In addition, our orthopedic surgeon may recommend the following blood tests before total disc replacement to help assess surgical risk:

• Coagulation Profile (PT, INR, aPTT): Evaluates blood clotting risk to help prevent excessive bleeding during and after surgery.
• Blood Type and Crossmatch: Identifies your blood group and prepares for possible transfusion if needed.
• Liver Function Tests (LFTs): Assess liver health, which is important for medication metabolism and recovery.
• Hemoglobin A1c (HbA1c): Measures long-term blood sugar control, especially important if you have diabetes.
• Serum Albumin Levels: Analyze nutritional status, which can impact healing and recovery after surgery.

What Are the Risks Associated With the Anterior Lumbar Approach?

The anterior lumbar approach is generally safe, but in some cases it may lead to vascular injury, nerve damage, or retrograde ejaculation (in men). You may also experience bleeding, infection at the incision site, damage to abdominal organs such as the intestines or ureters, or postoperative pain and swelling. Besides that, you may experience the following complications based on your overall health:

• Blood vessel thrombosis: Formation of clots in major vessels, which may affect blood circulation.
• Implant-related complications: Issues such as implant migration, loosening, or improper positioning.
• Delayed wound healing: Slower recovery at the incision site, especially in patients with underlying conditions.
• Scar tissue formation (adhesions): Internal scarring that may affect nearby structures over time.
• Adjacent segment degeneration: Increased stress on nearby spinal levels, leading to future degeneration.
• Anesthesia-related risks: Reactions to anesthesia, including respiratory or cardiovascular complications.

Moreover, a PubMed systematic review and meta-analysis of anterior lumbar surgery found an overall complication rate of 13.1% among 8,066 patients. The study also revealed intraoperative complications at 3.8% and postoperative complications at 7.4%. Infection rates were also low (1.5%), while reoperation was required in 1.7% of cases. However, the analysis found no significant difference in overall complication rates between open and mini-open techniques.

Can Anterior Lumbar Disc Replacement Improve Foraminal Height?

Yes, anterior lumbar disc replacement surgery can significantly improve foraminal height. This procedure restores intervertebral disc height, which indirectly increases the neuroforamen height (the opening through which nerves exit the spine). As the neuroforamen height increases, it relieves pressure on compressed spinal nerves, reducing symptoms such as leg pain, numbness, sciatic nerve pain, or tingling. However, if you have any of the following conditions, our spine surgeon may not recommend anterior lumbar disc replacement:

• Severe spinal instability: Excessive vertebral movement that requires spinal fusion instead of motion-preserving surgery.
• Advanced facet joint degeneration: Damaged facet joints that can lead to persistent pain after disc replacement.
• Severe osteoporosis: Low bone density that may not support proper implant fixation.
• Active infection: Ongoing infection in the spine or surrounding tissues.
• Significant spinal deformity: Conditions such as severe scoliosis that affect spinal alignment.
• Nerve compression from bony overgrowth: Cases where bone structures are the primary cause of compression and back pain.

Can Older Adults Have Minimally Invasive Anterior Lumbar Surgery?

Yes, older adults (including those over 75 or 80) can safely have minimally invasive anterior lumbar surgery. However, before the surgery, they must undergo a detailed preoperative examination to assess overall health and any existing medical conditions. To ensure safer recovery, our anterior lumbar disc surgery specialist may conduct the following tests before surgery:  

• Blood tests: Check for anemia, infection, blood clotting, kidney function, liver health, and overall metabolic balance status.
• Electrocardiogram (ECG): Assess heart rate, conduction patterns, prior ischemia, and cardiac fitness for anesthesia safety.
• Imaging studies: Assess alignment, spinal condition, nerve compression, and vascular anatomy for better surgical outcomes.
• Bone density scan (DEXA): Measures bone strength, fracture risk, and osteoporosis severity to guide implant choice.
• Medication review: To identify drugs that increase bleeding risk, interfere with anesthesia, or slow healing.
• Pulmonary function and chest assessment: Assesses lung capacity, oxygen exchange, and respiratory stability to reduce anesthesia-related complications.

After these tests, Dr. Georgiy Brusovanik carefully reviews the results to determine your surgical eligibility, minimize the risk of postoperative complications, and plan the safest and most effective anterior lumbar approach. He may also prescribe certain medications to strengthen bone support and promote optimal healing. Call 855-321-6784 to book a consultation with Dr. Georgiy Brusovanik.

Which Factors Improve the Success Rate of Anterior Lumbar Surgery?

Good bone quality, no existing medical conditions, and proper preoperative assessment increase the success rate of anterior lumbar surgery. Stable spinal alignment, healthy body weight, strong core muscles, and good vascular anatomy also increase the success rate of anterior surgery. Other than that, our spine doctor, Dr. Georgiy Brusovanik, may recommend the following strategies to maximize anterior lumbar surgery success:

• Nutritional optimization: Ensure proper intake of protein, calcium, and vitamin D to promote bone healing.
• Smoking cessation: Stop smoking before surgery to improve blood circulation, bone healing, and fusion success.
• Weight management: Achieve a healthy body weight to reduce mechanical stress on the spine and surgical implants.
• Preoperative exercises: Strengthen core and back muscles to stabilize the human spine and support safe postoperative movement.

Doctor’s Insight: In some cases, following these preoperative strategies may help you manage lower back pain, leg pain, numbness, or tingling, and potentially avoid surgery.

How Much Motion Can Be Preserved After Lumbar Disc Replacement?

After lumbar disc replacement, the motion preserved at the treated spinal segments typically ranges from 1.9° to 9° per level. For instance, according to a ScienceDirect study of 108 patients who underwent two-level ProDisc-L implantation, the upper disc segment preserved an average of 9° (0°–19°) flexion/extension and 5.5° (2°–12°) lateral bending. Similarly, the lower disc segment showed 6.2° (0°–14°) of flexion/extension and 1.9° (0°–7°) of lateral bending. Most patients also reported significant improvements in the Oswestry Disability Index and VAS pain scores.

Which Exercises Improve Spinal Stability After Anterior Lumbar Surgery?

Pelvic tilts, bridging, bird-dog, transverse abdominis activation, and gentle hamstring stretches can help improve spinal stability and speed up the recovery after Lumbar ADR. Similarly, side planks, hip bridges with marching, cat-cow stretches, mini-squats, and wall sits further strengthen the core glutes. Here are some additional exercises that can support stability and strengthen your muscles during recovery:

• Heel Slides: Lie on your back with knees bent, then slowly slide one heel away from your body while keeping your core engaged. Return to the starting position and repeat on the other side.
• Seated Marching: Sit upright in a chair, engage your core, and slowly lift one knee at a time. Keep movements controlled and avoid leaning backward.
• Standing Hip Abduction: Stand straight and lift one leg out to the side while keeping your torso stable. Lower it slowly and repeat on the other side to strengthen hip stabilizers.
• Quadruped Arm Raises: Start on your hands and knees, then slowly raise one arm forward while keeping your spine neutral. Hold briefly and return to the starting position before switching sides.
• Glute Squeezes: Lie on your back or sit comfortably, then tighten your glute muscles and hold for a few seconds. Release slowly and repeat to improve muscle activation.
• Step-Ups (Low Height): Use a low step and slowly step up with one foot, then bring the other foot up. Step down carefully and repeat to build lower-body strength.

Note: Do not perform these exercises during the early stages of recovery. Also, always consult with our surgeon before starting any new exercise routine to ensure safety and protect the healing spine.

How Long Does Post-Op Swelling or Abdominal Discomfort Last?

Swelling or abdominal discomfort improves within 2 to 6 weeks after minimally invasive anterior lumbar surgery, depending on surgical complexity. For example, if you had a single-level disc replacement, swelling usually subsides within 2–3 weeks. In contrast, if you had a two-level procedure or a previously failed fusion surgery, mild swelling may persist for up to 6 weeks.

However, if the swelling and abdominal pain last more than 6 weeks, worsen over time, or are accompanied by fever or unusual discharge, you should consult Dr. Georgiy Brusovanik immediately. Our spine surgeon, Dr. Georgiy Brusovanik, treats these complications with spinal injections, anti-inflammatory/antibiotic medications, minimally invasive drainage, and revision surgery (if needed).
