109 wrists from 69 cadavers (mean age 74 years) have been studied to clarify the pathology and morphology of the triangular fibrocartilage complex (TFCC) and to correlate pathological and radiological findings. Perforation of the TFCC was observed in 65% of the specimens and was considered to be secondary to a degenerative process, because it was often accompanied by degenerative changes in the ulnar carpal bones and perforation of the lunotriquetral ligament. To detect TFCC perforations on plain postero-anterior radiographs, it is important to evaluate ulnar plus variance and degenerative changes in the ulnar carpus. Existence of ulnar plus variance alone is more sensitive but less specific in detection of TFCC perforation than the existence of degenerative changes in the ulnar carpus.
对69具尸体（平均年龄74岁）的109个腕关节进行了研究，以阐明三角纤维软骨复合体（TFCC）的病理和形态，并将病理和放射学结果相关联。在65%的标本中观察到TFCC穿孔，且被认为是退变过程的继发表现，因为它常伴有尺侧腕骨的退变改变和月三角韧带穿孔。要在普通后前位X线片上检测TFCC穿孔，评估尺骨正向变异和尺侧腕骨的退变改变很重要。单独存在尺骨正向变异在检测TFCC穿孔方面比尺侧腕骨存在退变改变更敏感，但特异性更低。
