An interventional study of Dynamic CT and Arthrography in Joint Instability and Wrist Injuries, sponsored by Central Hospital, Nancy, France. Completed at 1 site in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-06-17.
Sponsored by Central Hospital, Nancy, France · Not applicable, Interventional, and Diagnostic
Compare various dynamic biomechanical markers (distances and angles) in the wrist during dynamic CT studies in three groups of patients: Normal subjects, with scapholunate instability and with other types of wrist instability.
Patients referred for the evaluation of wrist pain with CT arthrography will be eligible for inclusion. Patients will benefit from dynamic CT acquisitions before and after arthrography with three maneuvers: radio-ulnar deviation, clenching fist and dart throwing motion. Patients will also benefit from a wrist MR study on a 3 tesla scanner.
The morphology of the carpal ligaments will be evaluated on static imaging (MR and CT arthrograph) and on dynamic CT arthrography.
Distance and angular measurements will be obtained from dynamic CT studies using an appropriate post processing tool (4D-Ortho).
Data obtained with dynamic wrist evaluation will be correlated to ligament morphology, classical wrist instability criteria on conventional radiographs and with surgery (if available).
Exclusion Criteria:
No morphologic changes in carpal ligaments or clinical signs of wrist instability. Dynamic CT of the wrist will be performed before and after arthrography.
Device: Dynamic CT · Procedure: Arthrography
Morphologic ligament changes (e.g. partial or complete rupture) Dynamic CT of the wrist will be performed before and after arthrography.
Device: Dynamic CT · Procedure: Arthrography
Various low dose CT acquisitions will be successively performed on the wrist to allow a four dimensional evaluation. The same type of acquisition will be performed during various manoeuvers (radio-ulnar deviation, clenching fist, and dart-throwing motion).
percutaneous intra-articular injection of contrast media in the medio-carpal and radio-carpal joints
scapholunate diastasis (mm)
The distance between the scaphoid bone and the lunate bone will be measured during all maneuvers performed
Time frame: 1 day
Scapholunate angle
the variation in the scapholunate angle during the maneuvers performed will be assessed
Time frame: 1 day
Lunocapitate angle
the variation in the lunocapitate angle during the maneuvers performed will be assessed
Time frame: 1 day
Posterior radio scaphoid angle
The angle formed between the posterior most point of the scaphoid in the sagittal plane and the ventral and dorsal rims of the distal radius will be assessed
Time frame: 1 Day
