EVEREST® Degenerative Spinal System
Category: Degenerative, Thoracolumbar Fixation
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. The dual-lead thread pattern allows 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]
