A study of the interosseous distance between the radius and ulna during rotation of the forearm

A roentgenological and gross anatomical study of the variation in the interosseous distance between the radius and ulna during the rotation of the forearm was made on cadavers. It was found that the neutral position provides the widest interosseous distance at different levels of the forearm compared with all other supinatory and pronatory positions. The average of the interosseous distances is greatest at the junction of distal and middle thirds of the radius, except in pronation 90°.
