title: [Radiologic determination of the length of the distal end of the radius and ulna].
abstract: The influence of inaccurate positioning of the hand and forearm upon the relative lengths of the ulna and radius is investigated systematically in anatomical specimens and living persons. Increased or decreased ulnar lengths could be produced by moving up and down, by tilting or by pronation of the forearm. Extension of the elbow also influences the ulnar variance measurement.
