Osseointegrated transradial prostheses have the potential to preserve the natural range of wrist rotation by allowing controlled freedom of motion between implants in the forearm bones. Combining this technology with implanted neuromuscular electrodes has the potential to enable simultaneous proprioceptive-rich control of wrist rotation and myoelectric prosthesis. This improved prosthetic function would prevent compensatory shoulder and torso movements that deteriorate posture and potentially lead to secondary health problems over time.
The Scope of the thesis is to develop a new attachment device between the abutments and the prosthesis for transradial bone-anchored amputees, enabling the forearm rotation.
Studies and tests have been performed to understand which is the best configuration to allow the forearm rotation and ensure safety for the patient.
A new attachment has been designed to prevent uncomfortable feelings the patient is experiencing with the other device that allows forearm rotation.
The tests followed the design process realization of the new attachment device and its validation performing further tests.
