Forty-three patients with chronic wrist pain have been investigated prospectively with magnetic resonance imaging and arthroscopy. Pathology within the wrist joint was detected in 30 cases with magnetic resonance imaging and 32 cases with arthroscopy. The sensitivity and specificity of magnetic resonance imaging compared with arthroscopy were 0.8 and 0.7 for triangular fibrocartilage complex pathology, 0.37 and 1.0 for scapholunate ligament and 0 and 0.97 for lunotriquetral ligament. It is concluded that magnetic resonance imaging is unhelpful in the investigation of suspected carpal instability. In analysis of the triangular fibrocartilage complex, the results of magnetic resonance imaging should be interpreted with caution.
对43例慢性腕关节疼痛患者进行了磁共振成像和关节镜检查的前瞻性研究。磁共振成像检测出30例腕关节内病变，关节镜检查发现32例。与关节镜检查相比，磁共振成像对三角纤维软骨复合体病变的敏感性和特异性分别为0.8和0.7，对舟月韧带为0.37和1.0，对月三角韧带为0和0.97。结论是磁共振成像对疑似腕骨不稳定的检查没有帮助。在分析三角纤维软骨复合体时，应谨慎解读磁共振成像的结果。
