Reduction polyaxial screw
A reduction polyaxial screw is a pedicle screw with a multi-directional movable head and an extended reduction mechanism that allows easy rod capture and controlled spinal alignment. It combines flexibility with gradual reduction capability, making it ideal for complex spinal procedures.
A reduction polyaxial screw is an advanced pedicle screw designed with a polyaxial (multi-directional) movable head and integrated reduction features, typically in the form of extended tabs or towers. The polyaxial head allows angular freedom, enabling easier alignment of the spinal rod even when screw placement angles vary.
The reduction mechanism assists surgeons in gradually pulling the rod into the screw head, facilitating controlled vertebral reduction and correction of spinal deformities such as scoliosis, kyphosis, and spondylolisthesis. This reduces the need for excessive force and enhances surgical precision.
Manufactured from medical-grade titanium alloy or stainless steel, reduction polyaxial screws provide excellent strength, durability, and biocompatibility. After successful rod placement and locking, the extended tabs are removed or broken off, leaving a stable, low-profile construct.
Compared to reduction monoaxial screws, this design offers greater flexibility during implantation while still maintaining reliable fixation and alignment control.
