Part of the EVEREST Minimally Invasive system, this polyaxial screw features dual-lead threading for enhanced insertion speed and anchorage. Its mixed-metal Ti/CoCr tulip minimizes head splay and supports both rod diameters. Designed for use with the SERENGETI® retractor, it enables percutaneous placement with reduced tissue disruption. With CE and ISO certifications, it’s ideal for trauma, degenerative, and deformity procedures requiring precise alignment with minimal invasiveness.

It’s a cannulated polyaxial screw with a flexible head permitting 70° angulation. Dual-lead threads allow fast insertion with high pullout resistance. The mixed-metal tulip prevents head distortion under torque. Designed for use with SERENGETI® retractors, it enables percutaneous MIS placement while maintaining robust mechanical fixation.
The EVEREST 5.5 MIS Polyaxial Pedicle Screw is indicated for use in:
Percutaneous spinal fixation using MIS-TLIF or hybrid approaches
Rigid construct alignment in trauma or deformity surgeries
Multi-level constructs with minimal incision and tissue disruption
Revision procedures where rod diameter compatibility and alignment flexibility matter
Integration into TOOLMED’s systems or similar platforms offering 5.5/6.0 mm support
High alignment precision from polyaxial head and articulation
Efficient insertion and strong purchase via dual-lead thread
Improved durability under load due to mixed-metal interface
Enhanced minimally invasive workflow through cannulation and dedicated instruments
Supports both 5.5 mm and 6.0 mm rods for flexibility across cases
Dual-lead threading enhances pullout resistance and insertion efficiency. Mixed-metal Ti/CoCr tulip reduces head deformation under torque compared to all-titanium designs. The polyaxial head holds position once set, resisting angular displacement during cyclic loading.
Preoperative planning defines length and trajectory
Introduce guidewire under fluoroscopy to the pedicle entry site
Deploy cannulated dilators and SERENGETI® retractor sequentially
Advance screw over guidewire, control trajectory using ratcheting handle
Align screw tulips using head adjuster; contour and insert rods
Use reduction tools (Cicada™, Yellow Jacket™, BaseCamp) as needed for rod seating
Final tightening performed with torque-limiting wrench per system protocol
Following implantation, proper postoperative care is essential to ensure healing and prevent complications:
Confirm hardware placement via immediate postoperative imaging
Restrict spine loading and rotation for 6–12 weeks
Begin progressive rehabilitation focusing on core stabilization
Monitor implant integration, alignment, and hardware integrity in follow-ups
MRI or CT imaging remains feasible due to titanium-based components
The EVEREST 5.5 MIS Polyaxial Pedicle Screw merges high biomechanical strength with minimally invasive workflow efficiency. Its dual-lead thread, mixed-metal tulip, and cannulated design make it ideal for complex spinal stabilization procedures, offering surgeons precise control and flexibility across degenerative, deformity, trauma, and revision cases. CE and ISO certified, it’s a trusted choice within modern MIS spinal systems.
Polyaxial heads provide flexibility during rod insertion and positional adjustment, particularly useful in minimally invasive or deformity cases requiring alignment from variable trajectories.
No—dual-lead threads and robust shaft design preserve strength. Cannulation enables safe guidewire-guided insertion without compromising pullout resistance.
Yes—the screw accepts both Ø5.5 mm and Ø6.0 mm rods, allowing consistent use with TOOLMED or legacy systems.
Approximately 70°, permitting flexible orientation before final locking.
Yes—EVEREST reduction instruments like Cicada™, Yellow Jacket™, and BaseCamp support rod seating and alignment control in this system.
