As patients with lumbar conditions such as spinal stenosis and spondylolisthesis seek effective and less invasive solutions, a major innovation is revolutionizing spinal surgery: the TOPS system. Designed to stabilize the spine while preserving the natural mobility of the operated segment, this dynamic implant offers a promising alternative to traditional spinal fusion. Intended for patients between 40 and 75 years of age, it is particularly suitable for those who have not responded to conservative treatments after several months. Surgery using the TOPS system offers safe and scientifically validated care, performed in leading French centers, thanks to effective coordination with Quebec medical teams. This internationally recognized, high-tech device incorporates a transatlantic approach that guarantees patients personalized and comprehensive support throughout the surgical and postoperative process.

TOPS: a dynamic alternative to traditional fusion for lumbar stenosis

Spinal surgery traditionally performed for conditions such as severe lumbar stenosis or degenerative spondylolisthesis often relies on an arthrodesis procedure, in other words, a fusion of the vertebrae. This intervention, while often effective, results in stiffness in the operated segment, sometimes leading to pain or degeneration of adjacent vertebral levels. The TOPS system offers a completely innovative approach: it is a dynamic mechanical implant which, after surgical decompression, replaces the removed bone and ligament structures without permanently immobilizing the vertebral segment.

Therefore, the main benefit is the preservation of segmental mobility, which allows for better overall postoperative spinal biomechanics. This characteristic limits secondary complications related to stiffening. The TOPS device allows controlled movement in flexion, extension, and axial rotation, reproducing the physiological movements of the lumbar spine.

How does the TOPS system work?

• Stabilization without rigid fusion: The implant maintains stability while allowing a natural range of motion between vertebrae L3 to L5.
• Nerve decompression: essential for relieving the symptoms of sciatic pain, it is facilitated by the surgery associated with the implant.
• Innovative materials: Made of titanium and polyurethane, ensuring durability and biocompatibility, these implants are CE approved and certified according to ISO 13485.

This technology is developed in partnership with renowned manufacturers of spinal implants such as Zimmer Biomet, Medtronic, and NuVasive, leaders in biomedical innovation. This choice ensures seamless integration with the patient's anatomy and long-term reliability.

Biomechanical benefits of TOPS and IntraSPINE dynamic implants

At the heart of innovations in spinal surgery, preserving natural movement while ensuring stability is a fundamental challenge. Dynamic implants such as TOPS or the IntraSPINE system allow for the restoration of spinal biomechanics without resorting to rigid fusion, a known risk factor for long-term complications. These technologies are part of a motion surgery approach, which aims for a balance between mobility and functional safety.

Mechanical function of dynamic implants

The TOPS system functions like a biomechanical hinge implanted on the operated segment. Unlike fusion, where two vertebrae are consolidated into a single unit, TOPS maintains the joint by allowing:

• A controlled movement in flexion-extension and rotation, mimicking natural spinal mobility.
• Post-decompression stability after removal of the structures compressing the nerves.
• A balanced distribution of forces avoiding overvoltage of adjacent segments.

The same principle guides IntraSPINE implants, which are placed between the joint processes to generate support while respecting the biomechanics of the spine. These devices provide lasting relief from pain associated with spinal stenosis and facet joint osteoarthritis.

Comparison	TOPS implant	IntraSPINE Implant	Traditional Spinal Fusion
Segmental mobility	Preserved thanks to the dynamic movement	Preserved, support between apophyses	Complete immobilization due to the merger
Impact on adjacent segments	Reduces the risk of degeneration	Reduces the load on neighboring levels	Frequent increase in stress and wear and tear
Flexion/Extension	8°/-2°	Similar amplitude	Impossible
Recovery time	Often faster	Often faster	Longer due to the merger

The devices offered by leaders such as DePuy Synthes, Stryker, Globe Medical, Spineart, Medicrea, SeaSpine, and Kisco International reflect this trend toward less invasive and biomechanically sound surgical solutions.

Safety, scientific rigor and clinical advances around the TOPS system

Surgical innovation must be based on rigorous scientific validation, particularly when it involves an implant designed to stabilize the spine. Several clinical studies, including the post-marketing trial identified NCT02234154, demonstrated the safety and efficacy of the TOPS system in a group of patients suffering from lumbar stenosis and spondylolisthesis.

These studies, conducted over a period of 24 months, confirmed:

• A significant improvement in motor function and a reduction in pain, as measured by validated indices such as the Oswestry Disability Index (ODI).
• A significant reduction in leg pain scores (VAS), indicating lasting relief.
• An improvement in clinical scales of functional capacity and quality of life (SF-36).

The very strict patient inclusion criteria (notably excluding subjects with severe scoliosis, insufficient bone density, or metabolic bone diseases) guarantee appropriate selection, thus ensuring reproducible and safe results. This scientific rigor is validated by the French National Authority for Health (HAS), whose full report is available online. here.

Inclusion criteria	Exclusion criteria
