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]
