USF inventors have developed a more efficient osteosurgical screw. This novel monoaxial/polyaxial screw design contains a new “saddle” component with a modified rod rocker and screw head for intraoperative manipulation of the screw in the sagittal direction. This innovative design represents the first surgical screw that has 3 degrees of freedom in both rotation and translational motions, totaling 6 degrees of freedom. By incorporating a specialized series of interlocking parts, this improved screw design maintains the advantages of the increased maneuverability that comes with polyaxial screws, while also providing the stability of traditional spinal screws. This novel device allows for the correction of many vertebral deformities including rotational, longitudinal angulation, compression, malalignment, and burst distortions.
Competitive Advantages:
- Allows for both rigid and variable screw configurations
- Greater maneuverability
- Six degrees of freedom for increased intraoperative flexibility
- Maintains necessary stability
