Filter by:The study will consist of 3 parts. First a reference study is performed with healthy volunteers to investigate the viability of 4DCT scanning of the wrist for evaluating wrist bones configurations and movements (translations and rotations) during a new set of wrist motions that have not been evaluated in our previous study focused on the scapholunate ligament (NL72518.091.19). The following will be evaluated: the visibility of the DRUJ, the carpal metacarpal 1 (CMC-1) joint and the metacarpal phalangeal 1 (MCP-1) joint during clinically relevant wrist movements. Besides, in this study the difference is evaluated between between the left right wrist within participants during wrist motion. In future clinical practice the uninjured wrist may be used as a reference for the injured wrist, determining the left right difference in healthy volunteers will show the robustness of this technique. Subsequently a reliability study is performed to investigate the intra-patient test-retest reliability of our 4DCT scanning protocol. Lastly a diagnostic clinical study is performed on patients with chronic wrist pain, suspect for DRUJ instability. The objective of the clinical study is to determine the sensitivity and specificity of the 4DCT scan (during a series of movements in which DRUJ instability is predicted to be best visible) in the diagnosis of DRUJ instability in comparison with arthroscopic findings (gold standard). If the 4DCT shows to have a sensitivity and specificity comparable to that of wrist arthroscop
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.
