IntraSPINE®: an implant that protects nerve structures
09/15/25
The management of spinal pathologies is evolving considerably with the integration of innovative technologies such as the TOPS system, a major advancement in preserving lumbar spine mobility and preventing adjacent segment disease. This condition, common after traditional spinal fusion, results from overload and accelerated degeneration of the spinal segments adjacent to a rigid surgical site. The TOPS system is based on a sophisticated biomechanical design that maintains a certain range of motion at the treated level, while ensuring sufficient stability and protecting neighboring segments from premature wear. Numerous clinical and biomechanical studies now demonstrate the lasting benefits of this device, which is establishing itself as a credible alternative to traditional spinal fusion. merger classic rigid, especially for patients suffering from spinal stenosis with moderate degenerative spondylolisthesis.
The surgical environment in France, renowned for its expertise in spinal implants, combines innovation and safety with transatlantic support tailored to Quebec patients. Close collaboration between specialized centers, such as the TAGMED Clinic, and leading experts ensures a coordinated care pathway, from diagnosis to post-operative rehabilitation. This device, implanted via a standard posterior approach, faithfully reproduces the physiological movements of the vertebral segment while limiting excessive displacement that could cause pain or instability.
TOPS: A revolution in the prevention of adjacent segment disease
La maladie du segment adjacent (TSA) survient fréquemment après une fusion vertébrale, procédure qui élimine complètement le mouvement au niveau opéré. Cette absence de mobilité entraîne une surcharge biomécanique aux segments immédiatement supérieurs et inférieurs, augmentant leur risque de dégénérescence accélérée, notamment par l’apparition de hernies discales, facet arthrosis or even spondylolisthesis. The system TOPS distinguishes itself by recreating dynamic mobility in the segment operated, thus avoiding this abnormal transfer of constraints.
Developed by Premia Spine and scientifically validated by universities such as Ulm and by European and American field studies, this system is composed of titanium plates linked by a mobile mechanism that allows:
- Controlled axial rotation;
- Flexion and extension;
- Lateral flexion;
- Blocking excessive anterior and posterior translations.
This biomechanical mechanism faithfully reproduces the function of the natural vertebral elements (facets, ligaments) lost during surgical decompression. By preserving the mobility of the segment, TOPS protects adjacent segments by reducing their excessive stress..
An alternative to traditional rigid fusion splices
While traditional spinal fusion remains a gold standard for stabilizing certain severe spinal conditions, it has significant limitations. The rigidity it creates in one segment forces adjacent levels to compensate in order to maintain the flexibility required for daily activities, thus accelerating their wear and tear. This phenomenon can lead to recurring pain and the need for further surgical treatment. TOPS therefore offers a technological solution Who :
- Allows a faster functional recovery and facilitated a return to normal activities;
- Reduces complications related to adjacent segment syndrome thanks to its ability to maintain physiological mobility;
- Reduces the risk of secondary reintervention;
- Supports better biomechanical balance and improved long-term quality of life.
The choice between fusion or TOPS is based on a rigorous assessment taking into account the history, the type of pathology (including the presence of grade 1 spondylolisthesis), and the overall clinical context, with an emphasis on personalized follow-up.
For further information, a detailed overview is available on how the TOPS System.
The biomechanical and functional benefits of the TOPS system compared to adjacent segments
Au cœur de l’innovation, the TOPS system préserve la dynamique naturelle d’un segment vertébral en restituant une mobilité multidirectionnelle, ce qui est crucial pour la prévention de la maladie du segment adjacent. Cette prévention repose sur plusieurs mécanismes physiopathologiques complexes:
- Elimination of excessive stress on neighboring segments: unlike a complete fusion, TOPS distributes the load mechanically.
- Maintaining normal kinematics: The balance between flexion, extension, rotation and lateral tilt is maintained.
- Reduction of premature degeneration: The adjacent platforms, which are less in demand, are protected from the harmful effects of overload.
Biomechanical studies, notably those from the research of Professor Hans-Joachim Wilke at the University of Ulm, demonstrate that the TOPS system significantly reduces excessive movements and abnormal stresses that usually affect adjacent segments after fusion.
The following table summarizes the major differences between conventional fusion and the TOPS system:
| Criteria | Classical Spinal Fusion | TOPS System |
|---|---|---|
| Movement at the operated level | Eliminated | Preserved in all directions |
| Stress on adjacent segments | Increased, high risk of wear and tear | Reduced, effective protection |
| Risk of disease in the adjacent segment | Pupil | Significantly reduced |
| Functional recovery | Slow, delayed return to activities | Faster, improved mobility |
These observations highlight the growing interest in dynamic implants like TOPS, integrated into a broader range of innovations towards a back surgery Less invasive and more respectful of the body, the modern medical approach thus promotes the preservation of quality of life while maintaining a high degree of safety.
Furthermore, detailed eligibility criteria and implementation principles are disseminated by specialized experts and accessible on platforms such as the TAGMED CLINIC or via comparative analyses.
The transatlantic patient journey: expert coordination between Quebec and France
The care pathway for the implantation of a TOPS system is rigorously coordinated between Quebec and French medical teams, an essential collaboration for providing optimal care in an international context. This organization ensures:
- A first comprehensive assessment in Quebec, often in collaboration with the TAGMED Clinic, specializing in advanced conservative treatments such as Spinal decompression therapy;
