In 1912, Kappis described a posterior approach to the cervical and brachial plexus, which attempted to block the nerves at their point of emergence from the vertebral column.1 The posterior approach was advocated because the vertebral artery and vein lie anterior to the plexus.2 However, the needle must pass through the extensor muscles of the neck which causes considerable discomfort, and the long path of the needle is more hazardous. Consequently, this technique is not recommended as a routine for cervical or brachial plexus block.
