That means they will enable the full restoration of function that the bone it is replacing had.
What is special about these 3D printed bones is that because of the use of tricalcium phosphate, the body will remodel the implants into vascularised bone. The surgeon accepts the design and then once it is printed, it can be used in surgery. A hospital can perform an MRI which is then sent to Ossiform who create a 3D model of the patient-specific implant that is needed. Using these 3D printed bones is surprisingly easy. The company Ossiform specialises in medical 3D printing, creating patient-specific replacements of different bones from tricalcium phosphate – a material with similar properties to human bones. 3D printed bonesģD printing is an industry promising everything from cheap house building through to affordable rugged armour, but one of the most interesting uses of the technology is the building of 3D printed bones. In the future this could lead to wheelchairs controlled by the brain or assistance machines for tetraplegic patients. Over time the algorithm can then adjust to the individuals preferences and brain signals. The algorithm would then interprets signals from the brain using an EEG cap and automatically determine when the arm had made a move that the brain considered incorrect, for example moving too close to the obstacle or going too fast. In tests, the robot arm would perform simple tasks like moving around an obstacle. Thanks to a machine-learning algorithm, a robot arm and a brain-computer interface, these researchers have managed to create a means for tetraplegic patients (those who can’t move their upper or lower body) to interact with the world. One of the most interesting and practical uses we’ve seen tested so far comes from researchers at the Swiss Federal Institute of Technology Lausanne (EPFL). No longer a science fiction trope, the use of brain reading technology has improved hugely in recent years. Robot arm being used with brain signals © Alain Herzog 2021 EPFL
