Synovial cysts of the pulp of the little finger in three elderly patients were shown by arthrography to arise from leakage of synovial fluid from the wrist joint into the ulnar bursa and thence into the flexor synovial sheath in the digit. Distant as well as local sources of the contents of synovial cysts should be considered when the local anatomy permits communication between a degenerate joint and an adjacent tendon sheath.
关节造影显示，3例老年患者小指指腹滑膜囊肿是由于腕关节滑膜液漏入尺侧滑液囊，进而进入手指屈肌滑膜鞘所致。当局部解剖结构允许退变关节与相邻腱鞘相通时，应考虑滑膜囊肿内容物的远处及局部来源。
