Premium reduction polyaxial screw
A premium reduction polyaxial screw is a high-quality pedicle screw with a movable polyaxial head and an extended reduction tower, designed to facilitate easier rod alignment and gradual reduction of spinal rods during spinal fixation surgeries.
A premium reduction polyaxial screw is an advanced orthopedic implant used in spinal instrumentation systems for stabilizing and correcting the alignment of the vertebral column. It combines two important design features: a polyaxial movable head and an extended reduction tower.
The polyaxial head, connected through a ball-and-socket mechanism, allows the screw head to move in multiple directions. This flexibility helps surgeons align the screw head with spinal rods even when screws are inserted at different angles.
The reduction tower or extended head is designed to assist in gradually pulling or guiding the spinal rod into the screw head when the rod is positioned above the screw due to spinal deformity or misalignment. This feature makes rod placement easier and improves surgical efficiency.
The premium design refers to the use of high-precision manufacturing and medical-grade materials such as titanium alloy, which provide superior strength, durability, corrosion resistance, and biocompatibility. The threaded shaft is inserted into the vertebral pedicle, ensuring strong anchorage in the bone, while the rod is secured in the screw head using a locking cap or set screw.
Premium reduction polyaxial screws are commonly used in complex spinal surgeries, including spinal deformity correction and multi-level spinal stabilization procedures where both flexibility in alignment and strong fixation are required.
