Figure 5: Case of a 31-year-old male. (a, b) X-ray of the right wrist: anterior-posterior (a) and lateral (b) view. (c, d) T2-weighted magnetic resonance imaging in the sagittal (c) and coronal (d) plane, suspected diagnosis Palmer 1B lesion. (e, f) Hand arthroscopy of the same patient, showing a Palmer 2C lesion (e) and injected synovial villi at the radioscapholunate ligament (f). Figure 5(g) shows all anatomical planes in 1.5 T magnetic resonance imaging (top row, bottom left) and a three-dimensional reconstruction of the ulnocarpal disc region (bottom right) of the same patient. The defect cannot be visualized clearly in the standard planes from the MRI. The arrow points at the lesion in the ulnocarpal disc in the segmentation-based reconstruction, indicated by the flattened groove surrounded by two bulky tissue remainders on either side.
