A recent survey of congenital hand anomalies has revealed that symphalangism of the distal interphalangeal joint is more frequent than had previously been reported. To date, however, only 3 familial pedigrees have been documented in the literature. The family reported in this article had 9 individuals spanning 4 generations affected with symphalangism of the distal interphalangeal joint. In all cases, this was associated with ankylosis of the distal interphalangeal joint of the second through fifth toes. One child in the family also had brachyphalangism bilaterally as well as a bifid distal phalanx of the thumb. The world's literature does not seem to include a similar case. As with previous cases of fusion of the distal interphalangeal joint, there was little functional disability resulting from this anomaly and we do not recommend operative procedures to restore motion.
最近一项关于先天性手部畸形的调查显示，远侧指间关节融合畸形比之前报道的更为常见。然而，迄今为止，文献中仅记录了3个家族谱系。本文报道的这个家族有9名成员，跨越4代，均患有远侧指间关节融合畸形。在所有病例中，均伴有第二至第五趾远侧指间关节的强直。该家族中的一名儿童还双侧患有短指畸形以及拇指远节指骨分叉。世界文献中似乎没有类似病例。与之前远侧指间关节融合的病例一样，这种畸形导致的功能残疾很少，我们不建议采取手术恢复活动。
