| Intervention: In all groups both wrists will be scanned by our 4D-CT method during flexion/extension and radioulnair deviation. Same scans are obtained once again while axial loading is extended during flexion/extension and radioulnar deviation. 3 months after a reconstructive procedure the operated wrist is scanned again to evaluate and study the effects of such operations. A novel method for 3D dynamic imaging of the wrist is introduced, which uses Computed tomographic (CT) imaging. The open geometry of the CT provides a compliant workspace for several postures. Main study parameters/ endpoints: We expect to find changed motion patterns in wrist after a scapholunate ligament injury and even after reconstruction of this ligament. From this study acquired information would enable us to lay down the principles of a non-invasive tool for detection of carpal instabilities that occur after ligament injury. | — |
