The anesthesia (blockade) of canine n. femoralis may be performed either from lumbar or inguinal region. The insensibility of skin in the medial part of the thigh, tibia and tarsus as well as the akinesia of m. quadriceps femoris are attained by the anesthesia. The blockade of n. femoralis from the lumbar region often attains n. obturatorius as well. If the blockade of n. femoralis and n. ischiadicus was performed at the same time, almost all muscles of the hind limb (except m. pectineus, m. gracilis, m. obturatoris internus and m. adductor) would be inactivated, which may considerably facilitate minor surgical and postoperative interventions on the canine hind leg. Access to femoral nerve from lumbar can be recommended because of better results and easier performance and after the application of anesthetic the effect is faster and more efficient. The signs of the obturator nerve blockade were obtain in some dogs especially in dogs with long legs.
