Everest Minimally Invasive
Spinal System
The Everest Minimally Invasive Spinal System is a cannulated top-loading polyaxial pedicle screw system featuring the ability to accommodate titanium and CoCr rods of two different diameters. The dual-lead thread pattern allows for faster insertion and increased pullout strength [1]. The mixed-metal (Ti/CoCr) tulip minimised head splay and demonstrated improved biomechanical performance when tested against an all-titanium alloy screw [2]. These implants and instruments are cannulated for use with the Serengeti Minimally Invasive Retractor System.
