From Devastating Toddler Amputation to Becoming a Pioneer in Modern Bionic Innovation

At just 15 months old, Tilly Lockey faced a medical crisis that changed her life in an instant. The toddler from County Durham, England, was diagnosed with severe Group B meningococcal septicaemia, a fast-moving, destructive infection that pushed her body to the absolute brink of survival. Medical teams worked around the clock to save her, ultimately performing a life-saving operation that required the amputation of both of her forearms. While the news was heartbreaking for her family, her mother made a promise that night: one day, they would find a way to give Tilly her hands back.

Growing up, standard prosthetics proved heavy, awkward, and uncomfortable. Determined to find a better solution, Tilly and her family partnered with Open Bionics, a pioneering robotics team. Becoming a key tester for their multi-grip 3D-printed bionic arms, Tilly helped refine lightweight, accessible, and high-tech prosthetics that function through muscle signals. Rather than trying to hide her limb differences, she proudly embraced futuristic, customizable designs that empowered her independence.

Today, Tilly is an international advocate, model, and speaker who actively collaborates on creating life-changing 3D-printed bionic technology. Her incredible journey from surviving a fatal childhood illness to helping shape the future of modern prosthetics continues to inspire millions of amputees across the globe.
