Prevention of PostAmputation Pain With Targeted Muscle Reinnervation

In short: each transected nerve is identified after amputation and is dissected proximally for length. A nerve stimulator is used to identify functional motor nerve branches. Near the point where the motor branch enters the muscle, the motor nerve branch is transected and an end-to-end coaptation is performed with a nearby amputated nerve.

During the amputation a standard neurectomy will be performed based on the surgeons preference. Standard neurectomy will include cutting of the nerve, with or without traction, with or without coagulation, and with or without infiltration with a local anesthetic (i.e., ropivacaine) or phenol. Ligation of the nerve will not be allowed.
