[Studies of the discus articularis ulnae by use of arthrography of the wrist joint].

Lesions of the "discus articularis ulnae" (triangular fibrocartilage) are presented. Possible differences between the left and the right hand, as well as possible age and sex-linked differences were statistically analysed. In 22 wrist the disc was removed. The anatomical and pathological findings correlated with the arthrogram in all cases. Due probably to the advanced age of our study material disc lesions were found to be more frequent than in previous studies. The lesion was less frequent in men than in women. No difference could be shown between the left and the right hand. The arthrographic variations of the joint spaces adjoining the wrist were found to be symmetrically distributed. In no case could a communication between the wrist and the distal radioulnar joint be shown.
