Limb Replantation

Abstract

In previous studies, attention has been given to the technique¹and pathophysiology of limb replantation²in the experimental animal. Although many investigators have successfully replanted hind limbs in animals,^3-5detailed reports of the late results of replantation are incomplete. Lapchinsky⁶reported his experience with replantation of preserved canine limbs. Long-term evaluation of these dogs, including electromyographic determinations, revealed remarkable functional regeneration in transected limbs. The present report deals with the ultimate condition and functional capacity of successfully replanted canine hind limbs with special reference to more detailed examination of the neuromuscular system. Material and Methods Fifteen adult dogs, which had the left hind limb amputated at midthigh and immediately replanted, were followed for periods of 3 to 29 months. These animals were examined during this period and at the time of sacrifice with reference to the neuromuscular, circulatory, and osseous systems. The neuromuscular system was examined
