TOPS™: Preserve the Spine’s Natural Biomechanics

In the realm of spinal care, preserving the natural biomechanics of the spine during surgical intervention marks a pivotal stride in patient-centered therapy. The Total Posterior Spine (TOPS) System emerges as a groundbreaking innovation reshaping traditional approaches to lumbar spinal stenosis and degenerative spondylolisthesis. Unlike conventional fusion surgeries that immobilize spinal segments and frequently precipitate adjacent segment degeneration, the TOPS System endeavors to maintain motion without compromising stability. This distinction is critical for patients seeking relief from debilitating back and leg pain without sacrificing the long-term health and functionality of their spine.

Rooted in rigorous scientific research and cutting-edge biomechanical design, the TOPS System achieves a delicate balance between decompression and dynamic stabilization. It offers patients the potential to return to more active and fulfilling lives while mitigating complications common in fusion procedures. As we explore the facets of this technology, the intricate relationship between spinal movement preservation and therapeutic effectiveness will become apparent—a testament to innovation in spine care that is transforming patient outcomes internationally.

Understanding the TOPS System: Revolutionizing Lumbar Spine Surgery with Motion Preservation

The Total Posterior Spine (TOPS) System represents an innovative approach to lumbar spine surgery designed to address conditions such as spinal stenosis, spondylolisthesis, and facet arthrosis. Unlike traditional spinal fusion that permanently locks adjacent vertebrae, the TOPS implant replaces the anatomical structures removed during decompressive surgery, restoring near-normal motion across flexion, extension, lateral bending, and axial rotation.

The implant consists of a mechanical device situated between two titanium plates, anchored to the spine using four polyaxial pedicle screws. This configuration supports dynamic spinal mobility while simultaneously stabilizing the segment, preventing excessive forward or backward motion. The sophisticated engineering behind the TOPS facilitates bending, twisting, and straightening motions that closely mimic the natural movements of a healthy spine.

Key Features and Mechanism of Action

• Multiaxial Mobility: Enables motion in all physiological planes – flexion, extension, lateral bending, and axial rotation.
• Stabilization Without Fusion: Restricts harmful translations while allowing controlled movement.
• Replicates Natural Anatomy: Replaces the lamina and facet joints, maintaining the function of ligaments such as the supraspinous and interspinous ligaments.
• Minimal Load on Pedicle Screws: Innovative crossbar design reduces stress on pedicle screws, promoting longevity and stability.
• Implant Anchoring: Four polyaxial pedicle screws secure the device firmly via a posterior surgical approach.

These features distinguish the TOPS System as a potential alternative to fusion devices from established industry players including Premia Spine, Orthovative, and Elite Brain & Spine. Such partnerships and technology endorsements accentuate the system’s integration into contemporary surgical protocols.

Clinical Evaluation and Indications for the TOPS System in Spinal Pathologies

Dr. Sylvain Desforges, with over 30 years of expertise in spinal evaluations, emphasizes the paramount importance of patient selection in the efficacy of the TOPS System. Candidates generally present with moderate to severe lumbar spinal stenosis, degenerative spondylolisthesis grade I, or facet arthropathy leading to neurogenic claudication and chronic pain unresponsive to conservative management.

Patient evaluation involves comprehensive imaging including MRI, CT scans, and dynamic X-rays to determine the extent of ligamentous and bony involvement. Functional assessments frequently use the Visual Analog Scale (VAS) for pain and the Oswestry Disability Index (ODI) to quantify disability severity:

• Inclusion Criteria: Persistent symptoms with VAS and ODI scores ≥40 despite 3-6 months of non-operative treatment.
• Exclusion Criteria: Prior fusion surgery, spondylolisthesis grade II or higher, morbid obesity (BMI >40), and severe scoliosis (>10 degrees).
• Imaging and Diagnostics: Identification of single-level pathology between L2-L5, with L4-L5 being the most common surgical site.

This rigorous selection framework ensures the TOPS System is reserved for patients who stand to benefit most from motion-preserving arthroplasty, reinforcing Dr. Desforges’ commitment to evidence-based, ethical clinical decision-making aligned with Canadian standards.

Criterion	Details
Age Range	35–80 years
Bone Integrity	Absence of osteoporosis or metabolic bone disease
Previous Surgery	No prior fusion; prior decompression allowed
Severity of Spondylolisthesis	Grade I or less

Biomechanical Advantages of TOPS Compared to Fusion Surgery

The hallmark of the TOPS System lies in its ability to preserve spinal motion postoperatively, addressing a key limitation of spinal fusion surgery, which permanently eliminates movement at the operative segment. Spinal fusion shifts mobility demands onto adjacent segments, often accelerating their degeneration, a phenomenon known as adjacent segment disease.

TOPS maintains controlled motion at the affected vertebral level, thereby protecting neighboring segments from increased stress and strain. This design reduces the progression of degenerative changes adjacent to the surgical site, which is common following fusion techniques employed by leading manufacturers such as DePuy Synthes and Zimmer Biomet.

• Preservation of Range of Motion: TOPS retains 80-85% of normal flexion-extension, lateral bending, and axial rotation movement.
• Reduced Load Transfer: Adjacent vertebral levels undergo less compensatory load, decreasing long-term degeneration.
• Biomechanical Stability: Provides immediate stabilization without sacrificing physiological kinematics.
• Implant Durability: Pedicle screw anchoring system distributes biomechanical forces evenly to reduce fatigue failure.

Biomechanical studies, supported by research from institutions like Ulm University and Cleveland Clinic, demonstrate how TOPS successfully replicates natural facet joint mechanics, with detailed analyses available here.

Parameter	TOPS System	Spinal Fusion
Operative Level Mobility	Preserved (80-85%)	Eliminated (0%)
Adjacent Segment Stress	Minimal increase	Significant increase
Risk of Adjacent Segment Disease	Reduced	Elevated
Load on Pedicle Screws	Evenly distributed	Higher peak forces

Surgical Technique and Postoperative Recovery in TOPS Procedures

The surgical approach for implanting the TOPS System involves a posterior midline incision and standard lumbar decompression. Dr. Desforges underscores that, due to the device’s design, surgeons can perform a wide decompression without the constraints imposed by traditional fusion procedures. This results in comprehensive relief of nerve root compression while preserving spinal stability.

The procedure entails the following stages:

1. Patient positioning: Prone on a Jackson frame to maintain neutral lordosis and ease surgical access.
2. Exposure: Subperiosteal dissection of paravertebral musculature limited to facet joint exposure, preserving surrounding ligaments where possible.
3. Decompression: Complete laminectomy and facetectomy of the affected segment to relieve neural impingement.
4. Implant Trial and Sizing: After decompression, trial templates ensure correct implant fit to maintain anatomic alignment.
5. Pedicle Screw Insertion: Fluoroscopy-guided placement with optimal triangulation to maximize screw pullout strength.
6. Device Implantation: The TOPS system is secured to pedicle screws, with intraoperative imaging confirming placement accuracy.
7. Closure: Layered closure facilitated by meticulous deep fascia repair to ensure wound integrity.

Postoperatively, patients typically mobilize within 24 hours without the need for external braces, fostering rapid rehabilitation and return to daily activities.

Postoperative Milestone	Typical Timeline	Notes
Early Mobilization	Within 24 hours	Encouraged to reduce risks of complications
Hospital Stay	2-3 days average	May vary depending on individual recovery
Return to Light Activities	4-6 weeks	Progressive increase in activity levels recommended
Full Recovery	3-6 months	Dependent on preoperative condition and compliance

The Importance of Conservative Treatment Before Considering Motion-Preserving Surgery

Emphasizing prudent clinical pathways, Dr. Desforges advocates for exhausting conservative therapies over a period of three to six months before evaluating surgical options such as the TOPS System. Conservative management may include:

• Physical therapy targeting spinal stabilization and flexibility.
• Pharmacologic interventions, such as anti-inflammatory medications.
• Epidural steroid injections or facet joint injections for pain control.
• Advanced non-surgical modalities including neurovertebral decompression available at the Clinique TAGMED.

Notably, neurovertebral decompression therapy at TAGMED offers a non-invasive avenue to reduce nerve root compression, potentially postponing or avoiding surgical intervention. When such treatments have not been optimized, Dr. Desforges advises pursuing them prior to contemplating surgery to ensure a clear indication for procedural intervention and to enhance surgical outcomes.

Treatment Type	Goals	Duration Recommended
Physical Therapy	Improve spinal support and reduce pain	3–6 months minimum
Medications	Manage inflammation and discomfort	As medically indicated
Epidural Injections	Temporary pain relief	Limited frequency for safety
Neurovertebral Decompression	Reduce nerve pressure non-invasively	Variable, monitored by specialists
