Abstract

Purpose: The objective of this prospective study was to assess the value of the indirect MR arthrography (MR-AR) of the wrist in the detection of lesions of the TFCC. Material and methods: indirect MR-AR was performed in 45 patients (23 f/22 m) with unclear ulnar wrist pain. After i.v. injection of0.1 mmol/kg Gd-DTPA and after a motion-phase of the wrist (15 minutes) MRIwas performed in a coronal plane. We used a STIR-, a fatsaturated (fs) T1-SE and a 3D-DESS sequence. The images were evaluated by two radiologists using a consensus score. The lesions were assigned to the system of Palmer and correlated with arthroscopy. Results: Indirect MR-AR showed in 35 of 45 patients a lesion of the TFCC, but arthroscopy only revealed a defect in 32 cases. This means three false positive but no false negative assessments byMRI. Using this MRI protocol sensitivity and specificity in the detection of TFCC lesions were calculated as 100% and 77%. The accuracy was 93%. Small degenerative changes of the fibres were most common (Palmer type IIA). Intrauma patients the ligaments usually showed tears near the insertion at the ulna (Palmer type IB). The sensitivity and specificity was 88% and 95% for evaluation of the scapho-lunate (SL) ligament, the accuracy was 93%. Arthroscopy and MRI did not diagnose any rupture of the lunate-triquetral (LT)ligament. Conclusion: Indirect MR-AR is a non-invasive method with a high sensitivity in the evaluation of the TFCC and associated injuries. Therefore, it is an excellent screening procedure to assess the indication for therapeutic arthroscopy.
