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].

Main features

  • Mixed-metal (Ti/CoCr) tulip minimized head splay and demonstrated improved biomechanical performance when tested against an all-titanium alloy screw [2,3,4]
  • 70° polyaxial range of motion with posable friction head is designed to facilitate rod placement
  • Dual-lead thread pattern allows for easy insertion and increased pullout strength [1]
  • Self tapping: Designed to eliminate a step
