The Arcad® Staple was designed to help achieve optimum compression for fusion.
Delivered at ambient temperatures, the Nitinol (NiTi) ASTM F2063 memory metal structure induces balanced inward (“pushing”) forces. By pre-loading the staple with the Arcad® Forceps, the legs are then inserted into the guided pilot holes. Once the forceps are released, the memory of the metallic alloy exerts a compressive force on the legs as demonstrated in the diagrams above.
Immediate and continuous compression; the implant goes to work upon impaction and maintains compression throughout the course of treatment.
