S4® Element

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.

Features:

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.
     

Instruments

• Operational Simplicity
  • S4® Element offers streamlined instrumentation to facilitate efficiency in the
    OR workflow.
• Slim Profile Technology
  • Slim profile of instruments designed to allow smaller incision and easy
    instrument manipulation in tight anatomical spaces, while the low-profile
    screw reduces anatomical impingement.
• Minimal Surgical Conversion Risk
  • Rescue technique and instrumentation design aim to reduce risk of converting from MIS to an open procedure. 

Intended Use
The S4 Spinal System implants are used for dorsal monosegmental and multisegmental
stabilization of the lumbar and thoracic spine.
