Evaluation of a temporary arteriovenous shunt to establish neovascularization in a musculocutaneous flap: an experimental study.

abstract：BACKGROUND:Partial tibial nerve transfer to the motor branches of tibialis anterior is an emerging reconstructive technique for the treatment of traumatic common peroneal nerve (CPN) injury; however, few papers in the literature describe clinical outcomes. METHODS:A prospective single-surgeon series of nine consecutiv...
