A clubbed thumb or stub thumb, known clinically as brachydactyly type D (BDD),[1] is a genetic trait characterized by the last bone of one or both thumbs being short and round with an accompanying short and wide nail bed.[2]

The condition is sometimes known as murderer's thumb, a name originally coined by fortune-tellers,[3] potter's thumb[1] or Dutch thumb.
