【 摘 要 】

The distribution of the nervus fibularis communis was analyzed in 30 equine fetuses, mongrel, from the collection of the Animal Anatomy Laboratory at the School of Veterinary Medicine of Universidade Federal de Uberlândia, which were injected and stored in an aqueous solution of 10% formaldehyde. It was found that this nerve emerges from the ischiadicus, divides itself into nervus fibularis profundus and nervus fibularis superficialis distributing to the musculi extensor digitorum lateralis, extensor digitorum longus, fibularis tertius, and tibialis cranialis. Drawing an imaginary line in the medial-lateral region of the tuberositatis tibia, the nervus fibularis communis may be blocked in its proximal portion, in the caudal third, between the tendon of insertion of the biceps femoris and the lateral side of the musculus gastrocnemius (medium third); and the nervus fibularis profundus may be blocked in the proximal tibia, cranio-distally to the nervus fibularis communis. The block of nervus fibularis profundus may be performed in two regions of the tibia: proximal, considering the imaginary line, distal to the site referred to the nervus fibularis communis, and caudal to that described for the nervus fibularis profundus; and distal, on the lateral side of the tibiotarsal joint, between the tendons of insertion of the musculi extensor digitorum lateralis and extensor digitorum longus.
