Duplication of the thumb is not an uncommon condition and the biphalangeal type is considered to be a sporadic event. We report the familial occurrence of a unilateral thumb polydactyly type 4 of Wassel (12) or preaxial polydactyly type 1 of Temtamy (11).
拇指重复畸形并非罕见病症，双指骨型被认为是一种散发事件。我们报告了1例家族性发生的Wassel 4型（12型）单侧拇指多指畸形或Temtamy 1型（11型）轴前多指畸形。
