Targeted Muscle Reinnervation of a Muscle-Free Flap for Improved Prosthetic Control in a Shoulder Amputee: Case Report

We report a case of targeted muscle reinnervation of a muscle free flap for improved prosthetic control in a patient who had an amputation of the left upper extremity at the level of the shoulder after a severe electrical burn. The reinnervated muscle free flap receives signals from the brachial plexus, and these signals are amplified to provide an interface for a myoelectric prosthesis. This allows for more coordinated and efficient control of the artificial limb.
