Tailored Solutions, Smarter Care

Imagine a world where every prosthetic socket starts with a tailored, evidence-based design - one that reduces guesswork and saves clinicians' valuable time. That's exactly what riiForm's workflow delivers.

By providing a simple model to customise each socket fit digitally, we support clinicians to find the optimal socket fit for each patient, reduce the need for multiple check sockets and speed up the delivery of comfortable definitive devices.

Radii's mission has always been to empower clinicians to spend less time on repetitive tasks, and more time focused on patient care.

Our Fit workflow uses an extensive database of historical socket designs and patient outcomes to generate an initial tailored socket fit.

By analyzing similar scans and applying insights from past socket journeys, it suggests a design that aligns with each patient's unique anatomy. This isn't just automation: its precision, driven by evidence, to support clinical expertise.

Supporting every stage of the socket journey

With riiForm, you're not tied down by a 'pay-per-export' model. Instead, we cover the entire episode of care: from the first scan, through every adjustment, to the final, definitive fit. No matter how many check sockets are needed.

The result? Prosthetic care that's precise, intuitive, and focused on achieving the best outcomes for patients, without the hidden costs for complex cases.
