Arthroscopic findings in 11 patients with chronic ulnar painful wrist were compared both with arthrographic and magnetic resonance (MR) imaging results to evaluate the accuracy of the former procedure in the detection of triangular fibrocartilage complex (TFCC) lesions. MR imaging and arthrography investigations appeared to be sensitive modalities when compared with arthroscopic findings in TFCC lesions (specificity 100%; sensitivity 82 and 80%). MR imaging can be advantageously employed in the screening of patients suspected of having a TFCC tear, eliminating the necessity of an arthrographic examination. However, MR imaging could not define the exact site of the tear within the degenerate TFCC or detect lesions of the articular cartilage. Arthroscopy offers sure evidence of the site of TFCC lesion and more information about the intraarticular associated causes of chronic ulnar wrist pain such as chondromalacia and synovitis. An added benefit is that many of the pathologies seen can be treated using arthroscopic surgical techniques.
对11例慢性尺侧腕关节疼痛患者的关节镜检查结果与关节造影和磁共振成像（MR）结果进行比较，以评估关节镜检查在检测三角纤维软骨复合体（TFCC）损伤方面的准确性。与TFCC损伤的关节镜检查结果相比，MR成像和关节造影检查似乎是敏感的检查方法（特异性100%；敏感性分别为82%和80%）。MR成像可有效地用于筛查疑似TFCC撕裂的患者，从而无需进行关节造影检查。然而，MR成像无法确定退变的TFCC内撕裂的确切部位，也无法检测关节软骨损伤。关节镜检查能提供TFCC损伤部位的确切证据，以及更多关于慢性尺侧腕关节疼痛关节内相关病因的信息，如软骨软化和滑膜炎。另外一个好处是，许多所见病变可用关节镜手术技术进行治疗。
