This experiment with skeletal muscle autografts in monkeys was designed to retest previous findings that transplanted skeletal muscle can regenerate to a functional degree in primates without predenervation and to test a new hypothesis that increased functional demands on regenerated muscle grafts in monkeys may result in improved functional capacity of the grafts. Rhesus monkey index flexors were replaced with free palmaris longus muscle autografts with microneural anastomoses between the graft motor nerve and the severed profundus motor nerve. One monkey was taught selective index flexion before grafting and continued with this program after grafting to test the effect of training on the graft. Mature grafts were evaluated for in vivo contractile properties and by histology and histochemistry and were compared with a group of normal Rhesus palmaris longus muscles. The results reconfirm the capacity of nonpredenervated monkey skeletal muscle grafts to regenerate and to achieve some contractile ability and suggest that training of free muscle grafts may enhance recovery of their functional and structural properties.
