Fusion Principles
The methods for safely and effectively fusing two bones together across a synovial joint have been independently established and validated over decades of research and clinical experience by the AO Foundation. These fusion principles include minimal tissue disruption, thorough joint preparation, and rigid fixation. They have been applied to most joints in the body, including the ankle, as shown to the right. SAIL Fusion is the first to apply AO fusion principles to the sacroiliac joint through the design of our BowTie SI Fusion System and its surgical technique.
Voice of the Surgeon
In a survey of more than 120 surgeons, the consensus is clear:
A better solution to sacroiliac fusion is needed.
Why BowTie?
The BowTie system owes its name to the bowtie shape of the implant, which maximizes rigidity of the fused SI joint by resisting motion in all planes. Maximizing rigidity is one of the core AO principles to effectively fuse a joint. The bowtie shape (also known as a double dovetail) has been used in woodworking for centuries as an effective means of rigidly joining two structures. In fact, examples of bowties can be found in the world around us where quality craftsmanship is utilized.
