title: Restoration of full mass in nerve-intact muscle grafts after delayed reinnervation.
abstract: A rat muscle freely grafted with the motor nerve intact becomes restored to full mass and contractile function, in contrast to the reduced weight of a standard free graft. By crushing the nerve to a nerve-intact graft and delaying reinnervation, full mass is still restored. One can conclude that earlier reinnervation is not the reason for the success of nerve-intact grafts, but that it is rather due to reinnervation along preserved Schwann cell channels.
