radial paralysis
caused by loss of function of the radial nerve. See Table 14. Manifested by loss of function of extensor muscles and impaired sensory perception in the thoracic limb especially over the dorsum of the paw. Lesions at or distal to the level of the elbow result in difficulty in extending the carpus and foot so that weight may be carried on the dorsum of the foot. Lesions above that level, usually associated with injury to the brachial plexus, also cause an inability to actively extend the elbow (dropped elbow) and the animal cannot bear weight on the limb.
