[Compression neuropathies of the ulnar nerve in occupational diseases of the arms].

Features of forming and course of ulnar nerve compression neuropathy in the cubital and Guyin's canals were studied in 86 subjects, suffering from occupational diseases of the arms due to vibration and functional overstrain. Compression neuropathy of the ulnar nerve aggravates the vibration disease and arm disorders caused by functional overstrain--increases frequency, intensity and duration of paroxysmal paleness of the IV-V fingers, aggravates paresthesia, hypalgesia and hypothermia of the ulnar antebrachium, markedly decrease power of the hand, which must be taken into account when solving exert problems and carrying out treatment and rehabilitation.
