[Acroparesthesias due to damage of the nerves of the upper arm and forearm (author's transl)].

Compression syndromes of the radial nerve arise, for example, through pressure in the axilla from crutches or from pressure of the arm against a hard support during sleep. The mechanism is similar in lesions of the median nerves (irritation of the supracondylar apophysis, pronator syndrome). Lesions of the ulnar nerve usually arise from damage to the olecranon groove such as can be caused in manual workers in industry through constant flexion and extension of forearm. As treatment, a change of workplace is often sufficient. Anatomical changes must be removed surgically.
