ENHANCED BONE PURCHASE AND FIXATION^[1]

Tricortical fixation is achieved and mechanically constrained with FIREFLY^® MNG guides that enable accurate trajectories along high-skive bony anatomy and a path that provides optimal purchase through dense, cortical bone.

SMALL FOOTPRINT

The cortical bone trajectory along with the medialized MNG guide geometry enables minimally invasive, maximum muscle sparing^[2] spinal fixation which reduces blood loss^[3] and hospital stay^[4].

ADJACENT SEGMENT DISEASE SOLUTION^[5]

Cortical bone trajectory procedures are ideal for revision cases as they do not require the surgeon re-exposing the preexisting construct and FIREFLY^® MNG can be designed specifically to be compatible with the implanted hardware.
