Everest Degenerative
Spinal System
The Everest Degenerative Spinal System is a top-loading polyaxial pedicle screw system with the ability to accommodate titanium and cobalt chrome rods of two different diameters. [1] Dual-lead thread pattern for faster insertion and demonstrates increased pullout strength. [1] The mixed-metal (Ti/CoCr) tulip minimized head splay and demonstrated improved biomechanical performance when tested against an all-titanium alloy screw. [2]
Features
- Ability to accept Ø5.5 and Ø6.0 mm rods
- Everest set screw features a modified square thread design, facilitating set screw introduction
- Dual-lead thread pattern for faster insertion1
- Tapered distal third for increased pullout strength1
- Mixed-metal (Ti/CoCr) tulip minimized head splay and demonstrated improved biomechanical performance when tested against an all-titanium alloy screw2
