To investigate if using high-resolution 3-T MRI can identify additional injuries of the triangular fibrocartilage complex (TFCC) beyond the Palmer classification.
Eighty-six patients with surgically proven TFCC injury were included in this study. All patients underwent high-resolution 3-T MRI of the injured wrist. The MR imaging features of TFCC were analyzed according to the Palmer classification.
According to the Palmer classification, 69 patients could be classified as having Palmer injuries (52 had traumatic tears and 17 had degenerative tears). There were 17 patients whose injuries could not be classified according to the Palmer classification: 13 had volar or dorsal capsular TFC detachment and 4 had a horizontal tear of the articular disk.
Using high-resolution 3-T MRI, we have not only found all the TFCC injuries described in the Palmer classification, additional injury types were found in this study, including horizontal tear of the TFC and capsular TFC detachment. We propose the modified Palmer classification and add the injury types that were not included in the original Palmer classification.
研究使用高分辨率3-T磁共振成像（MRI）能否识别出帕尔默分类法之外的三角纤维软骨复合体（TFCC）的其他损伤。
本研究纳入86例经手术证实存在TFCC损伤的患者。所有患者均对受伤的手腕进行了高分辨率3-T MRI检查。根据帕尔默分类法分析TFCC的磁共振成像特征。
根据帕尔默分类法，69例患者可被归类为帕尔默损伤（52例为创伤性撕裂，17例为退行性撕裂）。有17例患者的损伤无法根据帕尔默分类法进行分类：13例为掌侧或背侧关节囊TFCC分离，4例为关节盘水平撕裂。
使用高分辨率3-T MRI，我们不仅发现了帕尔默分类法中描述的所有TFCC损伤，本研究还发现了其他损伤类型，包括TFC水平撕裂和关节囊TFCC分离。我们提出了改良的帕尔默分类法，并增加了原始帕尔默分类法中未包括的损伤类型。
