The system consists of pedicle screws, rods, set screws, cross connectors, lateral connectors, connectors, and bone hooks. The pedicle screws feature a coaxial cannulated design, supporting minimally invasive percutaneous pedicle screw fixation.
This design helps reduce surgical blood loss, muscle and soft tissue disruption, postoperative pain, incision size, and recovery time, while maintaining the fixation and reduction capabilities of conventional internal fixation.
The system is compatible with surgical navigation and robotic systems.
Through a posterior approach, pedicle screws are inserted into the thoracolumbar vertebrae through the pedicles. The screws can be manipulated to perform distraction, compression, lifting, and reduction, helping restore vertebral alignment and physiological spinal curvature.
The rod is introduced subcutaneously into the U-shaped slots of the pedicle screws using dedicated instruments and secured with set screws. The resulting construct provides a stable biomechanical environment for thoracolumbar spinal fixation and fusion.
The system is manufactured from TC4 ELI titanium alloy, Co28Cr6Mo cobalt-chromium-molybdenum alloy, and TA2G commercially pure titanium.
Pedicle screws provide three-dimensional spinal stabilization and correction through fixation of the vertebral pedicles and connection with longitudinal rods. They support distraction and compression maneuvers and are widely used for spinal fracture-dislocations, deformities, lumbar spondylolisthesis, and spinal instability.
The rod connects the pedicle screws and transfers spinal loads. Titanium alloy rods provide high stiffness, good biocompatibility, and reliable maintenance of sagittal and coronal alignment after contouring.
The system offers standard, break-off, and reduction set screws. The break-off mechanism is designed to provide consistent locking force and reduce variation during manual tightening.
Pedicle screws are available in fixed and multi-axial configurations. Multi-axial screws provide greater flexibility in screw positioning and angulation, facilitate rod insertion, and improve intraoperative adaptability.
The system provides multiple configurations, including different pedicle screw diameters and lengths and various pre-contoured rod lengths, allowing selection according to individual surgical requirements.
• Minimally Invasive Fixation: Cannulated pedicle screws support percutaneous fixation techniques and smaller surgical approaches.
• Flexible Configuration: Multiple screw, rod, and set screw options accommodate different clinical requirements.
• Correction Maintenance: The system supports spinal reduction and helps maintain postoperative correction.
• Secure Fixation: Physiologically oriented thread designs provide reliable holding strength.
• Reliable Performance: Excellent fatigue and corrosion resistance support long-term load-bearing applications.
• Good Biocompatibility: Titanium and cobalt-chromium-molybdenum alloy components are suitable for spinal implantation.
• Imaging Compatibility: Designed to support postoperative imaging and MRI examination.
Suitable for posterior spinal internal fixation procedures for degenerative spinal diseases, spinal trauma, and other conditions requiring thoracolumbar stabilization.
• Fractures and traumatic spondylolisthesis
• Correction of fracture malunions
• Severe or recurrent lumbar disc herniation
• Spinal instability or spondylolisthesis
• Stabilization and reconstruction after laminectomy for spinal stenosis
