Premium polyaxial screw
A premium polyaxial screw is a high-quality pedicle screw with a movable (polyaxial) head, designed for spinal fixation systems. The adjustable head allows multi-directional alignment with spinal rods, making surgical implantation easier while maintaining strong spinal stability.
A premium polyaxial screw is an advanced orthopedic implant used in spinal instrumentation systems to stabilize and align the vertebral column during spinal surgery. It features a polyaxial head connected to the screw shaft through a ball-and-socket mechanism, allowing the head to move in multiple directions. This flexibility enables surgeons to easily align the screw head with spinal rods, even when screws are placed at different angles in the vertebrae.
The term “premium” indicates improved design quality, advanced manufacturing precision, and the use of high-grade biocompatible materials such as titanium alloy. These materials provide excellent strength, corrosion resistance, lightweight properties, and compatibility with the human body.
The screw is inserted into the vertebral pedicle, where its threaded shaft anchors securely in the bone. After placement, a spinal rod is positioned into the screw head and secured with a locking cap or set screw, forming a stable spinal fixation system. Premium polyaxial screws may also include enhanced thread designs and surface finishing to improve bone grip and long-term stability.
These screws are widely used in spinal fusion procedures, spinal deformity correction, trauma stabilization, and degenerative spine treatments, where both ease of surgical placement and reliable fixation are important.
