Madrid Hospital Creates First Bone Metamaterial Prosthesis, Prevents Leg Amputation
The 300-gram titanium implant can bear more than 500 kilos and helped the patient keep his leg after cancer destroyed his tibia.
- Surgeons at Hospital Gregorio Marañón in Madrid implanted the world's first personalized metamaterial bone prosthesis, saving 38-year-old patient Pierre from amputation using aerospace-derived lattice technology.
- A high-grade sarcoma in Pierre's tibia, combined with previous infection and severe bone density loss, made standard implants impossible and left amputation as the only medical option.
- Developed by the Advanced Planning and 3D Manufacturing Unit , the 300-gram implant bears 500 kilos. Oncological surgeon Rubén Pérez said the lattice design lets the human body "take it as its own," avoiding mechanical rejection.
- Nearly a year after surgery, Pierre has had no complications and walks without crutches. A subsequent fall that fractured his other leg proved the printed tibia withstood significant real-world stress.
- Personalized implants for a wrist and sternum are under development at the hospital. Pérez hopes this aerospace-derived technology will eventually become available to any patient in Spain through the public health system.
