The sciatic nerves of 10 rabbits of the New Zealand strain were cut and isolated in the latero-posterior region of the thigh under general anesthesia. Immediate homograft technique was used in animals. The maximal motor conduction velocity of the sciatic nerve was measured in all the animals before the cutting of the nerve. Long-term EMG and anatomo-pathological controls were carried out. The results obtained are discussed. Further research will be continued by applying new techniques and new EMG parameters as well as more sophisticated anatomo-pathological techniques.
