The Mia Hand bionic hand was produced by Italian robotic prosthetic hand company Prensilia. This animal, which mimics the human hand, also has five fingers that can be bent in several different places.
A woman whose arm was amputated in a farm accident 20 years ago was fitted with a prosthesis. He was the first below-elbow amputee to receive this highly integrated bionic arm.
The research group developed a neuromuscular implant that connects to the nervous system It is located in a limited area around the two places where the patient attaches to the bones. To control the prosthesis, the woman used nearly the same nerve resources as her missing biological arm.

Fitting prosthetics to limbs and managing them are two different tasks. To solve these, researchers developed a human-machine interface that allows the artificial structure to be properly attached to the patient’s skeleton during the osseointegration process. In the future, this will make it possible to add additional electrodes that are implanted into nerves and muscles to connect to the body’s nervous system.
osteointegration It is a direct structural and functional connection between the patient’s living bone and the artificial implant (in this case, a bionic limb structure made of titanium). This is a complex procedure that requires the radius and ulna to be aligned and loaded with the same weight, which limits the space around them for other necessary components.

Combining osseointegration with reconstructive surgery, implantable electrodes and artificial intelligence, scientists managed to restore the functions of the hand. The level of amputation below the elbow is particularly problematic, and the level of functionality achieved marks a significant milestone in the field of complex limb reconstruction in general.
In addition to daily tasks that involved weight bearing and controlled movements (holding a cup or using a zipper), it also reduced phantom pain.. As a result, the need to take painkillers was eliminated. Persistent pain is the reason many amputees give up on traditional prosthetics.
