Where bone, nerve and machine become one.
Prof. Max Ortiz Catalán develops bionic limbs that connect directly to the human skeleton and nervous system, and treatments that free people from phantom limb pain.

Three frontiers, one mission: restoring what was lost.
From the operating room to the clinic to conflict zones, two decades of research turned into technologies people use every day.
Bionic limbs
The first prosthesis integrated directly into a patient’s bone, nerves and muscles, with a sense of touch delivered straight to the nerves. In daily use for over 10 years.
Research & publications → 02 / PainPhantom limb pain
Phantom Motor Execution (The Lancet, 2016), Progressive Motor Training and the Stochastic Entanglement hypothesis: making PLP the exception, not the rule.
Towards eradication → 03 / HumanitarianRehabilitation without borders
Based in Ukraine, supporting the rehabilitation of more than 100,000 people with amputations, with missions across Southeast Asia, Africa and Latin America.

Intention
Machine-learning algorithms decode motor volition from bioelectric signals, so the user simply thinks the movement.
Neural & muscular interface
Implanted electrodes on nerves and surgically reconstructed muscles capture stable, high-quality control signals.
Skeletal integration
An osseointegrated implant anchors the prosthesis directly to the bone: no socket, full range of motion.
Sensation
Direct nerve stimulation lets users perceive touch from their prosthetic hand, closing the loop between body and machine.
