Cutaneous distribution of infraclavicular, supraclavicular, and axillary blocks

Approximate cutaneous distribution of the infraclavicular, supraclavicular, and axillary block are similar and are shown in this graphic, though there is interpatient variability. This represents the distribution of axillary block if a musculocutaneous nerve block is performed as part of the block. For further details refer to UpToDate content on these blocks.
