Interosseous ligaments: device for applying stress in wrist MR imaging.
To improve visibility of the interosseous ligaments at magnetic resonance (MR) imaging of the wrist, the authors made and tested a device to apply ulnar and radial stress. In two men with small lunotriquetral (n = 1) and scapholunate (n = 1) ligament defects, depiction became evident only with stress deviation. Stress testing with this device increased the diagnostic accuracy of MR imaging for detection of these lesions.
