Design The Phantom® ActivCore™ Nail has an outer sheath with a proximal Flex Coil design and inner sliding core which allows for constant post-operative non-weight bearing compression to accommodate up to 8 mm of bone resorption across the joints The Nail is sterile packaged and pre-loaded and can simply be activated by releasing the Tension Screw after implantation; this allows the inner core to compress against the Ø7.2 mm Calcaneal Pegs and translates the outer sheath proximally The Flex Coil design aids in stress sharing as the Nail finds its way through the contoured tibial anatomy PRECISION® Guide technology Allowing for reproducibility when placing a Ø3.0 mm Drill-Pin from distal to proximal, through the center of the calcaneus and up to the tibia Placement Distal end of Nail is Ø13.3 mm through the subtalar and tibiotalar joints Fit Upon initial release of the Tension Screw, the inner core translates proximally The Calcaneal Threaded Pegs stay fixated in the bone and cause the calcaneus to be pulled proximally Indications Tibiotalocalcaneal arthrodesis Provide stabilization of the hindfoot and ankle including the transverse tarsal joints coupling the mid-foot to the hindfoot Technical specifications Rigid and stout Outrigger with Cam Lock technology allows for more accurate placement of Pegs Variable (0°-18°) angle placement of the Ø7.2 mm Threaded Calcaneal Peg allows for maximum boney purchase based on individual patient anatomy Proximal Peg Extension Arm attaches to the Outrigger allowing the surgeon to accurately place a Ø5.0 mm Threaded Tibial Peg into the 250 mm and 300 mm Nail lengths Screws The Nail is offered in 11 different size options with three diameters (Ø10.0 mm, Ø11.5 mm, and Ø13.0 mm) and four lengths (175 mm, 200 mm, 250 mm, 300 mm) for diverse patient anatomy Peg offerings Length Options Length Options Diameters Ø5.0 mm Ø7.2 mm Lengths 20–70 mm(2 mm increments) 45–120 mm(5 mm increments) Headed ✓ — Headless — ✓ Threads Full Threads Full Threads Placements Tibial Nail Slots Calcaneus Slotand STJ Hole Material Type II Anodized Titanium Alloy Type II Anodized Titanium Alloy
