Abstract
Posteroanterior wrist radiographs of eight patients were evaluated by eight orthopedists. Radial inclination angle and radial-carpal distance were measured by use of a standardized technique. The standard deviation for radial inclination angle was 2 degrees. The standard deviation for radial-carpal distance was 1 mm. The measured rotational variation of radial inclination and radial-carpal distance is 1 degree and 1 mm, respectively, through a 10-degree arc of supination and pronation.
