Can the Diagnostics of Triangular Fibrocartilage Complex Lesions Be Improved by MRI-Based Soft-Tissue Reconstruction? An Imaging-Based Workup and Case Presentation

Figure 2

Plastination of the triangular fibrocartilage disc complex. Sagittal section, from medial (a) to lateral (d) in a similar plane and orientation for plastination (left) and magnetic resonance imaging (right). Collagens are stained in red; cartilage is in blue. Note the anchoring of the TFCC at the distal ulna (a) and the fibrous continuity of the complex (b–d). (a, b) DRU = dorsal distal radioulnar ligament; LL = lower lamina^#; PRU = palmar distal radioulnar ligament; TF = triangular fibrocartilage; UL = ulnolunate ligament; UL = upper lamina^#; UM = ulnomeniscal homologue; UT = ulnotriquetral ligament; T = triquetrum; U = ulna; d = dorsal; di = distal; pa = palmar; pr = proximal. (c, d) DRU = dorsal distal radioulnar ligament; RL = radiolunate ligament; L = lunate; R = radius; U = ulna; d = dorsal; di = distal; pa = palmar; pr = proximal. ^#Nomenclature adapted from Benjamin et al.
