With twenty years of clinical history, PEEK-OPTIMATM polymers were the first medical-grade PEEK used in spinal fusion surgeries offering distinct clinical advantages due to their inherent properties including:
Now, spinal rod components made from PEEK-OPTIMATM Natural are being used to achieve semi-rigid fixation with posterior pedicle screw systems as an alternative to metal. From rod breakage and screw loosening to accelerated degeneration at adjacent spinal segments, the high stiffness inherent with all-metal constructs are believed to contribute to clinical challenges and negatively impact patient outcomes.1,2 In response, surgeons have indicated that a range of stiffness would benefit patients.2
With a lower stiffness and radiolucency, patients may benefit from PEEK-OPTIMATM Spinal Rod Components due to:
