简要总结
To quantitatively assess distal radio ulnar joint (DRUJ) stability, a pressure-monitor ultrasound system was developed. The objective of this study was to evaluate the force-displacement relationship of DRUJ in patients and normal subjects. Each subject will be imaged sitting with elbow flexed and forearm pronated. The dorsal surface of distal radius and the center of ulnar head will be displayed at DRUJ level. The pressure toward palmar direction will be applied to distal ulna with different levels of transducer displacements, i.e. 1 mm, 2 mm, and 3 mm. The distance between the dorsal surface of the ulnar head and the dorsal surface of the distal radius will be measured. At the same time, the pressure to the transducer will be measured.
