The brachial plexus is vulnerable to intrinsic and extrinsic compression or entrapment and perioperative damage. Anesthesia for lateral antebrachial cutaneous nerve requires two injections. Research. JBJS. At the supraclavicular level, however, the elements of the plexustrunks, divisions, and cordsinterlace and interlink, and hence the connective tissues containing these nerves interconnect, a feature observed when they are dissected.8This interconnection would allow for a more even spread of injected solution, a phenomenon that is observed clinically.21This is distinctly different at the axillary level, where the terminal nerves do not interconnect and the connective tissues surrounding them create distinct compartments for each.16Fourth, side effect profiles may be explained by the interconnection, via tissue planes, of the anatomical compartments across which the nerves travel. Journal of Korean medical science. It passes the elbow joint just medial to the brachial artery and in front of the brachialis muscle. Coronal and corresponding axial section for 2 subjects. Surface landmarks are identified by drawing one line along the superior border of the scapular spine and then bisecting it with a second line drawn parallel with the vertebral spine.
