The emergence level of the musculocutaneous nerve from the brachial plexus: implications for infraclavicular nerve blocks.
In this cadaveric study we assessed the level of the emergence of the musculocutanous nerve (MCN) relative to needle insertion site during infraclavicular block. ⋯ This anatomical study suggests that MCN may be one of the factors explaining MCN block failure for the single-injection technique of infraclavicular block using lateral needle trajectory.
