[Measurement of the strength of pronation and supination forces and its significance in radius fracture displacement].
The strength of pronation and supination was measured by "Forearm-Rotate-Dynamometer" on 524 male and female students ranging in age from 16 to 32. The study showed that the strength of supination was 13% greater than that of pronation for 91.3% of all the tested subjects (1048 sides). Based on this finding, the pattern of displacement fracture of the middle lower segment of the radius was discussed. It was concluded that the proximal fragment displacement will show supination, adduction and flexion when a proximal fragment displacement occurs.
