To evaluate the accuracy of magnetic resonance (MR) in the detection of tears of the triangular fibrocartilage complex (TFCC), 10 consecutive patients with posttraumatic chronic wrist pain were examined with MR, arthrography, and arthroscopy and the results were compared. The MR images of 16 control subjects were also examined to define the MR appearance of the normal TFCC. When compared with arthroscopic findings, both MR and arthrography had two false-negative results (sensitivity, 80%) and no false-positive results. Regarding the sites of the TFCC tears, the findings on MR did not always correlate with the findings on arthrography. In no case was MR able to visualize the cartilaginous lesions visible by arthroscopy. These preliminary results illustrate the ability of MR to assess the integrity of the TFCC and suggest its use as the first imaging technique following plain radiography in the evaluation of patients with chronic posttraumatic pain on the ulnar side of the wrist.
为评估磁共振成像（MR）检测三角纤维软骨复合体（TFCC）撕裂的准确性，对10例连续的创伤后慢性腕关节疼痛患者进行了MR、关节造影和关节镜检查，并比较了结果。还检查了16例对照受试者的MR图像，以明确正常TFCC的MR表现。与关节镜检查结果相比，MR和关节造影均有2例假阴性结果（敏感性为80%），无假阳性结果。关于TFCC撕裂的部位，MR检查结果与关节造影检查结果并不总是相关。在任何情况下，MR都无法显示关节镜可见的软骨损伤。这些初步结果说明了MR评估TFCC完整性的能力，并建议在评估腕关节尺侧创伤后慢性疼痛患者时，将其作为平片后的首选成像技术。
