All surgeons and intraoperative staff will be blinded from the experimental treatment. All procedure is the same for every patient in the operating suite. Patients will receive the standard-of-care surgical repair of their digital nerve with microscopic magnification and using fine-gauge sutures. Every patient will have 2 fine-gauge Teflon insulated wires (sterilized at the hospital where the surgery is done) inserted proximal to the nerve injury site, away from the suture site, 3 days pre-operatively and immediately post operatively. Those wires will be attached to the electrical stimulator that activates the nerve and send action potentials towards the cell body. For that reason, the patient must not receive local anesthetic because that would block the sodium channels, abolishing action potential propagation and nullify the effects of electrical stimulation.
