简要总结
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.
详细描述
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).

结局指标
主要结局
Posterior radio scaphoid angle
时间窗: 1 Day
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
Scapholunate angle
时间窗: 1 day
the variation in the scapholunate angle during the maneuvers performed will be assessed
Lunocapitate angle
时间窗: 1 day
the variation in the lunocapitate angle during the maneuvers performed will be assessed
scapholunate diastasis (mm)
时间窗: 1 day
The distance between the scaphoid bone and the lunate bone will be measured during all maneuvers performed
