Over a period of twenty years a small number of patients, thirty-one, have been seen who suffered injuries of the infraclavicular brachial plexus as a direct result of skeletal injury in the region of the shoulder joint.

Except for isolated circumflex nerve injuries the prognosis is generally good whatever part of the plexus is damaged. The treatment is conservative and its two most important features are prevention of stiffness of joints and the control, by regular galvanic stimulation, of denervation atrophy of muscle during the often prolonged period before recovery becomes apparent.
