RELIABLE NAVIGATION

Cervical pedicle screw trajectories can be difficult to achieve and reproduce without navigational aid, yet standard robotic or image guided navigation isn’t widely accepted within the cervical spine due to hypermobility and intervertebral movement. FIREFLY® CNG provides unsurpassed navigational accuracy that is independent of any intraoperative motion.

SAFE RESULTS

Subaxial cervical pedicle screw fixation is achieved using FIREFLY® CNG by mechanically constraining and directing the drill and tap along a safe, accurate, and reproducible trajectory. A complete surgical plan is presented with the patient-matched CNG prior to surgery to ensure a thorough understanding of the patient’s anatomy and optimized surgical precision.

ENHANCED BONE PURCHASE AND FIXATION

The cervical pedicle screw trajectories defined by FIREFLY® CNG provide optimized implant placement, length, fit, and fill when compared to traditional lateral mass screws. These pedicle screws have a mean pullout strength 4x greater than that of lateral mass screws^[2] and also take advantage of fixation in more robust bone, enabling longer constructs that cross the cervical-thoracic junction.
