To determine if there is an association between wrist ganglia and internal derangements of the wrist joint by reviewing magnetic resonance (MR) images.
Two observers retrospectively reviewed MR images of the wrist obtained in 625 patients at 1.5 T for the presence of ganglia and associated triangular fibrocartilage complex, scapholunate ligamentous, or lunotriquetral ligamentous tears that were within 3 mm of the ganglion. When available, surgery and/or pathology records were reviewed.
There were 122 ganglia and 37 internal derangements. Of the 22 ulnar-sided ganglia, 10 (45%) demonstrated associated triangular fibrocartilage complex tears. Of the 97 radial-sided ganglia, 27 (28%) demonstrated ligamentous tears related to the site of the ganglion. The radial-sided tears involved the radial aspect of the triangular fibrocartilage complex in 12 ganglia; the scapholunate ligament, in isolation, in eight ganglia; and both the triangular fibrocartilage complex and the scapholunate ligament in six ganglia. Only one of the ganglia demonstrated an associated lunotriquetral ligamentous tear. Surgical findings confirmed the ligamentous tears in 25 patients.
Wrist ganglia are associated, not infrequently, with internal derangements of the wrist.
通过回顾磁共振（MR）图像，确定腕部腱鞘囊肿与腕关节内部紊乱之间是否存在关联。
两名观察者回顾性分析了625例患者在1.5T场强下获得的腕部MR图像，以检查腱鞘囊肿以及腱鞘囊肿周围3mm范围内是否存在三角纤维软骨复合体、舟月韧带或月三角韧带撕裂。如有手术和/或病理记录，也一并进行回顾分析。
共发现122个腱鞘囊肿和37例腕关节内部紊乱。在22个尺侧腱鞘囊肿中，10个（45%）伴有三角纤维软骨复合体撕裂。在97个桡侧腱鞘囊肿中，27个（28%）伴有与腱鞘囊肿部位相关的韧带撕裂。桡侧撕裂在12个腱鞘囊肿中累及三角纤维软骨复合体的桡侧部分；在8个腱鞘囊肿中单独累及舟月韧带；在6个腱鞘囊肿中同时累及三角纤维软骨复合体和舟月韧带。只有1个腱鞘囊肿伴有月三角韧带撕裂。手术结果证实了25例患者存在韧带撕裂。
腕部腱鞘囊肿常常与腕关节内部紊乱有关。
