The TRIGEN^◊ Hindfoot Fusion Nail  (HFN) brings the simplified instrumentation of the TRIGEN^◊ NAIL SYSTEM to the hindfoot. Until now, surgeons have been limited to only medial-lateral and posterior anterior locking options.

But now, the TRIGEN^◊ Hindfoot Fusion Nail takes locking a step further with an oblique locking configuration that allows surgeons to maximize thread purchase by locking into better bone. The TRIGEN^◊ HFN advantage allows surgeons to target screws through the calcaneus and into specific bones to attain the most stable construct while at the same time gaining fusion between the calcaneus and surrounding bones. Fusion is further aided by allowing screws to cross the articulating surfaces of the calcaneus and talus, as well as the calcaneus and cuboid bones.

Compared to other ankle arthrodesis nails that are currently available in the market, the TRIGEN^◊ Hindfoot Fusion Nail offers threaded distal screw holes for added stability and reduced risk of screw pullout. In addition, the surgeon may select not to use specific holes or to use shorter screws that allow the joint to maintain the ability to articulate. Rotational stability is also achieved by means of a static locking hole or dynamic compression slot in the proximal end of the nail.
