[Ultrastructural features of muscle spindle organization in a replanted limb].

It has been shown that in a month after replantation of extremity the muscle fibres survive. Some of them have got good safety, in others--destructive-degenerative changes prevail. The reinnervation processes were not perfect because of the disturbance of axon-Schwann interrelations and as a result of this--the presence of the degenerative forms of Schwann cells.
