Distribuição do nervo fibular comum em fetos de equinos (sem raça definida) e descrição anatômica de pontos para bloqueio anestésico

Abstract

We analyzed the distribution of the common peroneal nerve in fetuses of 30 horses, breed not defined, from the collection of the Laboratory of Animal Anatomy, Faculty of Veterinary Medicine, Federal University of Uberlândia, which were injected and stored in aqueous solution of formaldehyde at 10%. It was noted that this stems from the sciatic nerve divides into superficial and deep peroneal nerves, distributed to the lateral extensor muscles and long toe, peroneal and tibial cranial third. By drawing an imaginary line in the mid-lateral region of the tuberosity of the tibia bone, the common peroneal nerve can be blocked in its proximal part, the caudal third, between the tendon of insertion of the biceps femoris and lateral gastrocnemius lateral (middle third), and the deep peroneal nerve at the proximal tibia, distal to the fibular head-common. The superficial peroneal nerve block can be accomplished in two regions of the tibia: the proximal, considering the imaginary line, distal to the point referred to the fibular and caudal to that described for the deep peroneal, and distal side of the face tibio-tarsal, between the tendons of insertion of the extensor muscles of the lateral and long finger.
