73 patients with persistent ulnar wrist pain of undetermined origin were examined by Magnetic Resonance Imaging (MRI). A series of 15 coronal slices was acquired using a T2* weighted gradient echo sequence. With repetitive measurement of those three slices that showed the triangular fibrocartilage complex (TFCC) best, the carpus was imaged 12 times during radial-ulnar deviation in increments of five degrees. The single images were combined according to their slice positions and continuously displayed on an image workstation, allowing for kinematic evaluation. Three different types of impingement of the TFCC were identified.
