Inertia® Reduction Pedicle Screw

The INERTIA® Polyaxial Reduction Screw is designed to further complement the innovative design of the existing INERTIA Polyaxial Pedicle Screw range.

INERTIA Reduction Screws are designed for applications where the extent of the vertebral misalignment would not allow a standard sized tab pedicle screw to properly engage with the rod component of the system without using additional instrumentation. The Reduction Screw is designed with removable tabs that allow the surgeon to approximate the spine to the desired sagittal or axial profile. This new series of pedicle screws are particularly useful for the correction of spinal deformities, such as spondylolisthesis and scoliosis.
