The syndrome of brachial plexus damage is most often depicted as a dropping of the elbow and a knuckling over of the carpus and digits so that the dorsal surface of the digits rests upon the surface of the ground. The above description is often repeated in our veterinary textbooks; however, experimental procedures as well as clinical observations indicate that other manifestations may also be present and observed.
