“…4 On the basis of classical anatomical descriptions, we thought that the superficial ulnar nerve, if already blocked, could be exposed to nerve injury during localization of the deep radial nerve. Therefore we conducted this prospective, randomized study and compared two sequences: median, radial, ulnar, and musculocutaneous nerves vs median, ulnar, radial and musculocutaneous nerves in terms of ulnar nerve stimulation during the radial nerve localization and conversely.…”
