REDUCED SCREW PROMINENCE WITH BETTER ALIGNMENT

Compared to traditional iliac trajectory, placement of S2AI screws using the FIREFLY® Platform reduces screw prominence and improves screw head alignment with S1 screw heads without the use of a connector^[1] as the entry site is typically in-line with lumbar and S1 pedicle screws.

LOWER REVISION RATES

Compared to traditional iliac trajectory, placement of S2AI screws using the FIREFLY® Platform reduces screw prominence and improves screw head alignment with S1 screw heads without the use of a connector as the entry site is typically in-line with lumbar and S1 pedicle screws.^[2]

ENHANCED BIOMECHANICAL STRENGTH

The S2AI Screw trajectory has proven to provide a more stable form of fixation for long construct cases and better caudal anchoring points that can be utilized in both the adult and pediatric populations^[3][4][5].
