Scientists at Chalmers University of Technology in Sweden have created a new bionic implant that allows amputees to control all the fingers of a prosthesis. Research published in the journal Science Translation Medicine.
Prostheses that replace a lost limb are often difficult to control. Because patients can contract the muscles at will, another option is to use the stump muscles to control the bionic arms. However, this is much more difficult if the arm is amputated at the elbow. In addition, the fitting of prostheses can cause compression of the remaining limb, accompanied by discomfort and mechanical instability.
In the new study, the scientists used a titanium implant to attach prosthetics. They connected the preserved nerves with special sensors. The patient who underwent surgery was able to control each finger of the new bionic hand as if it were his own.
The operation was performed by Dr., who previously led the first hand transplant operation in Scandinavia. It was carried out by Paolo Sassu at the Sahlgrenska University Hospital in Sweden. The study included doctors and scientists from the United States, Sweden, Australia and Italy.
