Abstract
Radiography of 60 normal wrists was performed in 50 adults to determine the inclination of the distal joint surface of the radius. The central ray was directed 10 degrees proximally in postero-anterior projection and 15 degree proximally in lateral projection. The values obtained were compared with those from perpendicular projections. No dfferences were found between the two p.a. projections. In the lateral projection with the central ray directed proximally the measuring points were better defined, resulting in significantly increased exactness of the measurement. The mean value for the volar inclination was 9 degrees in the latter projection.
