The Whistler Modular Pedicle Screw System offers a versatile modular tulip that allows for screw insertion prior to attaching a tulip. This provides optimal in-situ visualization and flexibility to utilize three different tulip options after screws are placed. Tulips are available in a Low-top, Reduction-top, or Minimally Invasive-top. Screws are available in solid, cannulated, and HA coated.
