Phrenic nerve palsy following coracoid infraclavicular brachial plexus block

Various methods of infraclavicular brachial plexus block have been introduced in the past, of which Wilson’s coracoid infraclavicular brachial plexus block, a more lateral approach, consequently thought to be easier and safer.
