That peripheral nerves may be rendered incapable of conduction of voluntary impulses by indirect trauma of the type known as muscular action is too well known to merit stress; but that such paralysis may result from a single muscular compression, and especially that the paralysis may appear hours to weeks after the trauma, are facts that seem to have been largely overlooked by clinicians for years.
