2 S 4 Spinal System Small The S 4 Spinal System features a revolutionary pressure vessel design capable of delivering unmatched biomechanical stability while maintaining an exceptionally small implant volume. This low profile, low volume aspect of S 4 reduces the risk of facet and soft tissue impingement which ultimately leads to reduced soft tissue irritation. S 4 also features an inner Set Screw for locking the construct which improves distraction and compression maneuvers and allows a low run on the rod throughout all implant components. Stable The S 4 Spinal System features a unique closure mechanism that maximizes surface contact area which effortlessly stabilizes the whole construct and permits a high overall biomechanical strength. In addition, the interconnection strength between the bone screw and body is more stable due to a special shaped seat inside the body which creates the revolutionary pressure vessel that efficiently transfers force throughout the rod-screw construct. Lateral stability can also be achieved with S 4 using the various rigid and adjustable cross-connectors.

4 S 4 SRI Spondylolisthesis Reduction Instrumentation The unique design of the S 4 SRI facilitates simultaneous correction of translation and slip angle via the mechanism of levered derotation. The S 4 SRI is a mechanical apparatus that attaches to the pedicle screws and allows precise control of all facets of the reduction, providing a gradual and safe reduction. RI Minimal interspace distraction is required prior to reducing the spondylolisthesis, thereby limiting excessive nerve root tension. The system allows reduction of spondylolisthesis with single level fusion, leaving adjacent levels intact if desired.

The S 4 FRI allows the performance of three fracture reduction functions either individually or in combination: Distraction Compression Restoration of the original lordosis Modular distraction can be carried out with the FRI distraction forceps, or in very small increments by utilising the set wheel. The entire reduction procedure can be performed minimally invasive.

7 S 4 Spinal System From initial conception, the S 4 Spinal System was developed to meet the spine surgeon s need for an extremely low profile and incredibly stable thoracolumbar spinal fixation system. By combining the exceptionally small yet stable design of the screw construct with simple instrumentation, the S 4 Spinal System emerges as a reliable system for posterior column fixation. The development elements small, stable, simple, and safe define the S 4 Spinal System as a recent pedicle fixation system of choice for surgeons requiring performance oriented top-loading pedicle screw systems. Simple S 4 instruments were designed to meet the surgeons demand for a quicker yet simpler operational procedure. The multiaxial capability of the polyaxial screws provide 42 total range of motion, which allows for easier rod placement and reduction. The small implant volume greatly improves distraction and compression maneuvers, especially in narrow conditions, and enhances the surgeon s ability to place interbody fusion spacers when distracting off pedicle screws. By combining the S 4 Spinal System with the ProSpace interbody fusion spacers, Aesculap offers a true three-column stabilization portfolio. Safe The top-loading, inner Set Screw of S 4 features an exclusive undercut thread design that virtually eliminates cross threading. This unique undercut thread actually directs the forces inward to prevent splaying of the body, which ultimately results in improved force transmission and efficiency throughout the rod screw construct. The small volume and low profile design of the S 4 implant also minimizes interference with anatomical structures thereby allowing the surgeon the ability to remove less facet joint.
