S4® Element Spine System Posterior Thoracolumbar Stabilization System The S4® Element Spine System is a low profile and innovative thoracolumbar pedicle fixation system designed to address complex posterior pathologies. It includes an open and a minimal invasive instrument module. Basing the design of the S4® Element MIS implants on the S4® Element open implants aim to provide a minimal learning curve and easier transition to MIS. The S4® Element system is a top-loading low profile pedicle screw system that offers a broad selection of implants and instruments that are designed to meet the surgeons demand for a quicker yet simpler surgical procedure. The pedicle screw features a sophisticated pressure vessel locking design capable of delivering biomechanical stability while maintaining a low profile. Implants -Small implant volume -Maximize screw head range of motion. -Reduce the risk of facet and soft tissue impingement. Patented interlocking thread design -Minimize splaying of screw body. Pressure vessel technology -Transfer energy throughout the polyaxial screw construct transforming it into a solid monoaxial construct, achieving maximum construct stability. Undercut thread design -Help eliminate cross threading by directing the force inward, improving force transmission and efficiency throughout the rod-screw construct. Augmentation screws -Cement distribution through side slots. -Both augmentation screws and injection cannula are single sterile packed. Wide implant selection -Wide variety of connector implant sizes and styles enable compatibility with varying patient anatomies.
