Abstract: Disclosed herein a system and a method to detect an amputee's hand muscles movements for controlling an artificial limb prosthesis. The system may comprise a plurality of passive tag positions and wearable band with a plurality of on-board position readers. The plurality of on-board position readers may be configured to capture data associated with a first plurality of passive tags positions at a first moment, and capture data associated with a second plurality of passive tags positions at a second moment. The system may further include one or more processors configured to detect at least one of the muscle contraction, the muscle relaxation, and the muscle inactivity based on the data captured at the first moment and at the second moment, and thereby control the artificial hand prosthesis movements responsive to detection at least one of the muscle contraction, the muscle relaxation, and the muscle inactivity.

Abstract: A method and a device for replacing radioulnar joint are disclosed. The method may include inserting a distal stem into a distal part of the ulna bone, and inserting a proximal stem into the proximal part of the ulna bone. In addition, the method may include inserting a stem insertion part located at a proximal end of a mobile locker into the cylindrical-shaped opening of the proximal stem. The method further includes twisting the mobile locker so that the first semicircle-shaped opening and the second semicircle-shaped opening are aligned such that a spherical cavity is formed between the mobile locker, and inserting a mobile globe into the spherical cavity.
