* Required Field

Arcad® Staples are designed to facilitate fast and easy fixation in a variety of applications and once implanted, return to their shape memory compressed position. Dynamic and permanent compression is achieved at the arthrodesis or osteotomy site.

  • No heat activation required.
  • Fast and easy insertion.
  • Range of sizes available from 8-25mm.
  • Symmetric or asymmetric leg lengths to fit anatomy.
  • Simple intraoperative repositioning; if required.

One-piece Compressive Construct

The Arcad® Staples 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.

  • Migration resistant talons that allow for accurate placement and stable bone purchase.
  • Low profile / atraumatic contours that are designed to minimize soft tissue irritation.
  • Size range allows for precise fitting and anatomic compatibility.

Minimal Instrumentation

  • All required instruments are neatly configured in one elegant sterilization module.
  • Instrumentation facilitates simple insertion, repositioning, adjustments and removal.
  • The Implantation Forceps feature a unique Lock and Load design that permits convenient, reproducible deployment and rapid insertion.
