First cases were done by design surgeons Steven MacDonald (Western University, London, Ontario) and Steven Haas (Hospital for Special Surgery). It is designed around CORI handheld robotics, with a phased launch beginning in 2026 and broader availability through 2027.

Its NanoACTIV micro- and nano-textured surface is positioned for true arthrodesis across the SI joint rather than stabilization alone. The incumbent in that niche is SI-BONE's iFuse Bedrock Granite.

The FNF-ON8 score weights displacement (3 points), a superior subcapital fracture line (2), and age 45 or older, comminution and an inferior subcapital line (1 each). Osteonecrosis occurred in 4% of patients scoring 0 to 3 and 42% of those scoring 6 to 8; AUC 0.80 versus 0.70 for the Garden classification.
