Bloqueo axilar ecoguiado: variaciones anatómicas de la disposición de los 4 nervios terminales del plexo braquial en relación con la arteria humeral

Our results allow defining four different anatomical patterns, two based in the position of the musculocutaneous nerve and two based on the disposition of the ulnar nerve with respect to the humeral vein. These patterns were not related to laterality, gender or body weight.
