Triphalangeal thumb (TPT) is a rare congenital malformation where the thumb has three phalanges instead of two. Syndactyly is a condition in which children are born with fused or webbed fingers. The combination of TPT, Syndactyly, and thumb duplication is extremely rare, especially when these deformities are combined in one hand.
Hand abnormalities and polydactyl have been reported in a 1-year-old boy.
A clinical examination reveals two thumb duplications, finger fusion (Syndactyly), and a thumb with three phalanges (TPT). The diagnosis was based on clinical findings and an X-ray image of the hand.
The Z-plasty method was used to remove the adhesion between the thumb and forefinger, as well as the removal of the medial and distal phalanx of the thumb's medial tip.
The patient was followed for 2 months and found him in good health. To authors' knowledge, we described an unusual case from Syria, considered the first in medical history.
General and plastic surgeons should be aware about this unusual mix of the three abnormalities. The family history must also be carefully investigated to explore the occurrence of hereditary illnesses.
三叉手拇指（TPT）是一种罕见的先天性畸形，其拇指有三个指骨而不是两个。并指是一种儿童出生时手指融合或连在一起的情况。TPT、并指和拇指重复的组合极为罕见，尤其是这些畸形同时出现在一只手上时。
已报告一名 1 岁男孩手部畸形和多指。
临床检查显示两个拇指重复，手指融合（并指），以及一个拇指有三个指骨（TPT）。根据临床发现和手部 X 光片作出诊断。
采用 Z 成形术去除拇指和食指之间的粘连，以及去除拇指内侧尖端的内侧和远端指骨。
患者随访 2 个月，情况良好。据作者所知，我们描述了一个来自叙利亚的不寻常病例，被认为是医学史上首例。
普通和整形外科医生应该了解这三种异常情况的罕见组合。还必须仔细调查家族史，以探讨遗传性疾病的发生。
