In a review of 364 radiocarpal and 123 distal radioulnar joint arthrograms we identified 44 (12%) patients with contrast defects at either the proximal or distal surface of the carpal triangular fibrocartilage complex (TFCC). Differences in their arthrographic characteristics distinguished two separate groups of patients; one with similar and another with dissimilar appearing TFCC surface contrast collections. Thirty-one of our 44 patients had similar appearing, isolated radial-sided collections at either the proximal or distal TFCC surfaces. Our arthrographic, demographic, and historical study of these patients suggests that the collections are not caused by traumatic partial TFCC tears but represent a normal anatomic variant, probably a synovial recess at the radial TFCC attachment. Arthrography and dissection of a limited number of cadaveric specimens confirmed this conclusion. The second group included the remaining 13 patients. This group had contrast collections at either the proximal or distal TFCC surface, which varied in location and appearance. This smaller group is more likely to represent those uncommon patients with partial TFCC defects caused by tears.
在对364例桡腕关节和123例桡尺远侧关节造影进行回顾时，我们发现44例（12%）患者的腕三角纤维软骨复合体（TFCC）近端或远端表面存在造影剂充盈缺损。根据其造影特征的差异，将患者分为两个不同的组；一组TFCC表面造影剂充盈情况相似，另一组则不同。在我们的44例患者中，有31例在TFCC近端或远端表面出现相似的、孤立的桡侧充盈影。我们对这些患者进行的造影、人口统计学和病史研究表明，这些充盈影并非由TFCC创伤性部分撕裂所致，而是一种正常的解剖变异，可能是桡侧TFCC附着处的滑膜隐窝。对有限数量的尸体标本进行造影和解剖证实了这一结论。第二组包括其余13例患者。该组在TFCC近端或远端表面有造影剂充盈影，其位置和形态各不相同。这一较小的组更可能代表那些因撕裂导致TFCC部分缺损的罕见患者。
