EVEREST 5.5 MIS Polyaxial Pedicle Screw Insights

What is a EVEREST 5.5 MIS Polyaxial Pedicle Screw?

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.

Applications of EVEREST 5.5 MIS Polyaxial Pedicle Screw

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

Advantages of EVEREST 5.5 MIS Polyaxial Pedicle Screw

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

Biomechanics of EVEREST 5.5 MIS Polyaxial Pedicle Screw

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.

Surgical Technique of EVEREST 5.5 MIS Polyaxial Pedicle Screw

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

Postoperative Care of EVEREST 5.5 MIS Polyaxial Pedicle Screw

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

Conclusion

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.

FAQs of EVEREST 5.5 MIS Polyaxial Pedicle Screw

Why choose polyaxial over monoaxial screws in MIS?

Polyaxial heads provide flexibility during rod insertion and positional adjustment, particularly useful in minimally invasive or deformity cases requiring alignment from variable trajectories.

Does cannulation weaken the screw?

No—dual-lead threads and robust shaft design preserve strength. Cannulation enables safe guidewire-guided insertion without compromising pullout resistance.

Is it compatible with 6.0 mm rods?

Yes—the screw accepts both Ø5.5 mm and Ø6.0 mm rods, allowing consistent use with TOOLMED or legacy systems.

What motion range does the polyaxial head allow?

Approximately 70°, permitting flexible orientation before final locking.

Can existing reduction tools be used?

Yes—EVEREST reduction instruments like Cicada™, Yellow Jacket™, and BaseCamp support rod seating and alignment control in this system.
