Pain. Possible triangular fibrocartilage complex tear versus lunotriquetral ligament tear status post distal radius fracture Some sequences are limited by patient motion artifact. There is mild deformity of the distal radius and its articular surface reflecting a healing/healed fracture. There is a resultant small gap along the articular surface of the distal radius in the coronal plane, but minimal if any articular surface depression. There is also mild deformity of the tip of the ulnar styloid with underlying cyst formation, indicating prior trauma. Small ossicles are again noted along the dorsal aspects of the scaphoid and capitate perhaps representing ununited fracture fragments as seen on recent CT scan. Mild osteophytes affects the wrist.Contrast is present within the radiocarpal and midcarpal articulations. Contrast extends between the two articulations via a defect in the membranous portion of the scapholunate ligament; the dorsal and volar components of the ligament appear intact. The lunotriquetral ligament perforation suspected on the conventional arthrogram component of the study is not clearly evident on this MRI exam. No contrast is seen traversing the triangular fibrocartilage and entering the distal radioulnar joint indicate a full-thickness tear; however, there is mild generalized deformity and heterogeneity of signal of the articular disc, with contrast filling small defects along its distal surface suggesting partial thickness tearing. The tendons of the wrist are unremarkable.
