A Principled
Approach to SI Fusion
BowTie is the first SI fusion system inspired by longstanding, proven fusion principles independently established by the AO Foundation. The technology and surgical approach minimize tissue disruption, thoroughly prepare the joint, and provide rigid fixation.



Shallow inferior-posterior
approach avoids gluteal
neurovascular structures.


Direct longitudinal access to
joint allows for comprehensive
decortication of auricular surfaces.


Unique bowtie shape and
cortical placement resists
motion in all planes.
