STRUCTURAL PERONEAL NERVE REORGANIZATION FOR HEEALING OF CANINE LEG BONE FRACTURES
Reactive-and-destructive, compensatory-and-adaptive and regenerative reactions directed to homeostasis maintenance found in peroneal nerves in the experiments on modeling an comminuted leg bone fracture in 21 mongrel dogs and their treatment by transosseous osteosynthesis method. Numerical density of myelin conductors 8 % decreases only after 1 week of the experiment, and that of myelin-free ones 16–31 % decreases within three ﬁrst weeks, thereby evidencing their greater traumatization. In the experiment subsequent periods the number of nerve conductors increases, and the value maximum coincides in time with the period of fracture consolidation – from 42,0 to 50,0 days of the experiment. The results give reason to assume that the peripheral nerves play a crucial role in the processes of bone fracture healing by arborization of the nerve conductors and produced by them neuromediators.
