The Thoracolumbar Posterior Pedicle Screw and Rod System (CoCrMo Alloy) consists of pedicle screws, rods, set screws, crosslinks, lateral connectors, hooks, and other accessories.
The system is designed to restore spinal alignment, correct deformities, and provide biomechanical stability following posterior thoracolumbar procedures.
Pedicle screws are inserted through the vertebral pedicles and connected with contoured rods and modular components, supporting distraction, compression, derotation, and realignment maneuvers.
The assembled construct forms a stable three-dimensional fixation system that supports load sharing and facilitates spinal fusion.
Components are made of TC4 ELI titanium alloy, CoCrMo alloy (Co28Cr6Mo), and pure titanium (TA2G).
• Versatile Solutions: Accommodates diverse spinal pathologies and patient anatomies.
• Correction Maintenance: Helps maintain spinal correction and minimize postoperative angle loss.
• Secure Fixation: Bone-specific thread designs enhance anchoring strength and pullout resistance.
• Flexible Configuration: Various screw and set screw options provide greater surgical flexibility.
• Durable Performance: Excellent fatigue and corrosion resistance support long-term implantation.
• Biocompatibility: Implant materials provide good biocompatibility with reduced imaging interference.
• Modular System: Multiple components allow customized three-dimensional constructs for complex spinal deformity correction.
The system is intended for posterior thoracic, lumbar, sacral, and sacroiliac spinal fixation, fusion, and deformity correction in patients with the following conditions:
• Vertebral fractures and traumatic spondylolisthesis
• Post-traumatic malunion or nonunion
• Severe or recurrent lumbar disc herniation
• Spinal instability or spondylolisthesis
• Post-laminectomy instability due to spinal stenosis
• Stabilization after resection of benign, malignant, or metastatic vertebral tumors
• Posterior reconstruction after laminectomy for intradural tumors
• Post-debridement stabilization in discitis or low-grade intervertebral infections
• Reconstruction after debridement for spinal tuberculosis
• Congenital scoliosis
• Idiopathic scoliosis
• Kyphotic deformity correction
