Ankle Truss System
Arthrocube™ and Arthrosphere®
The Ankle Truss System (ATS) is an innovative solution for failed ankle replacements and limb salvage, offering standardized implants for faster treatment. Powered by Truss Implant Technology™, it is designed to promote bone growth, distribute load efficiently, and minimize subsidence. With digital pre-planning tools and specialized reamers, ATS can streamline surgery with a viable solution in patients whose only alternative may be amputation (BKA).
First of its kind fusion offering1
available for Foot & Ankle surgeons.
First product FDA cleared offering standardized sizes for failed ankle replacements and complex limb salvage cases.
Off-the-shelf sizes
First FDA cleared product offering standardized sizes for failed ankle replacements and complex limb salvage cases.1
Spherical reamers for foot & ankle
First acetabular reamers designed specifically for revision ankle fusion and limb preservation, including smaller sizes more commonly needed for this procedure.1
Foot & ankle focused
No more customs required. No more sourcing loose instruments. Everything you need in one place.
Care delivered faster
Instead of a 4-to-6 week typical waiting time for a custom designed implant1, time-sensitive patients can be treated as soon as next day.
Sizing options based in SOMA
Sizing options based on real patient anatomies from Prophecy & SOMA databases. Available sizing ranges designed to cover most patient anatomies.
Digital templates to pre-plan sizing
Optimize time in the operating room. Streamline sizing for optimized inventory in every case.
Fusion for patients who need it the most.
In a retrospective study, over 92% of patients showed fusion throughout the ankle joint using ATS implant technology, compared to the literature on IM nail with bulk allograft, showing 62.5% fusion rate.

Ankle Truss System Clinical Evidence included the retrospective study and two white papers (Raikin et. al' and Dekker et. al') reporting results of theirown ATS studies.
The Ankle Truss System data was compared to the two current standards of care: arthrodesis with just an IM Nail and arthrodesis with an IM nail + Bulk allograft.
Indicated for use with our comprehensive Ankle Fusion portfolio.
The Ankle Truss System is indicated for use with the T2 Ankle Arthrodesis Nail or the Valor Hindfoot Fusion Nail as part of a tibiotalocalcaneal fusion construct in a salvage procedure.
