For additional posterior stabilization

Posterior "Top-Loading" Pedicle screw System for simple and complex stabilization

After spinal surgery many cases require instrumentation to stabilize the spine during fusion. The MonoPoly system from SIGNUS is designed for use in the most common applications of posterior thoracolumbar stabilization. The system’s Top-loading screw design facilitates simple construct assembly.
