The Polyaxial Pedicle Screw is an advanced spinal implant used in thoracolumbar and lumbosacral spine fixation procedures. It is designed to provide strong vertebral anchorage while allowing multi-directional (polyaxial) movement of the screw head, enabling easier rod placement and improved spinal alignment during surgery.
This system is commonly used in spinal stabilization procedures such as trauma fixation, degenerative spine disease, deformity correction, and spinal fusion surgeries. The polyaxial head allows the surgeon to adjust the angle of the screw relative to the rod, ensuring optimal construct configuration even in complex anatomical conditions.
The screw engages deeply into the pedicle and vertebral body, providing strong fixation in both cortical and cancellous bone. Once the rod is positioned, the locking mechanism secures the head, converting the construct into a rigid and stable spinal fixation system.
Manufactured from premium medical-grade titanium or stainless steel (depending on configuration), the implant offers excellent strength, fatigue resistance, and biocompatibility. Precision threading ensures strong bone purchase and reliable long-term fixation.
Polyaxial pedicle screws are widely used in orthopedic spine surgery and neurosurgical procedures for spinal stabilization, deformity correction, and fusion support.
The system is fully sterilizable and supplied in professional surgical packaging for safe handling and efficient operating room workflow.
