Pain and popping sensation with history of scapholunate disassociation. LIGAMENTS: Intra-articular contrast is again identified within both the mid carpal and radiocarpal joints after intra-articular injection of the mid carpal joints was performed. Intra-articular contrast is again visualized traversing the scapholunate ligament, indicative of tear (series #901, images 59-68). Further, contrast appears to traverse the lunotriquetral ligament, new from prior examination and best seen on series #901, image 53 and confirmed by arthrogram.TRIANGULAR FIBROCARTILAGE COMPLEX: The triangular fibrocartilage complex appears intact without intra-articular contrast identified within the distal radioulnar joint.TENDONS: No significant abnormality noted. BONES: The previously visualized increased marrow signal within the triquetrum has improved in comparison to prior examination. No other significant abnormalities. ADDITIONAL
1. Findings consistent with disruption of the scapholunate ligament as described above. Further, the lunotriquetral ligament appears disrupted, a new finding in comparison to prior examination. The triangular fibrocartilage complex remains intact.2. Interval improvement of the bone contusion of the triquetrum.
