Triphalangeal thumb (TPT) is a congenital malformation where the thumb has three phalanges instead of two. The extra phalangeal bone can vary in size from that of a small pebble to a size comparable to the phalanges in non-thumb digits. The true incidence of the condition is unknown, but is estimated at 1:25,000 live births. [1]
The condition is known by numerous names including clubbed thumb or club thumb. [ 10 ] [ 11 ] American researcher R.A. Hefner used the terms "short thumb" and "brachymegalodactylism" in 1924, [ 3 ] and "short thumb" has continued to be used in a few other studies since then, including the study that defined Rubinstein–Taybi syndrome in 1963 ...
The classification of ulnar polydactyly exists of either two or three types. The two-stage classification, according to Temtamy and McKusick, involves type A and B. In type A there is an extra little finger at the metacarpophalangeal joint, or more proximal including the carpometacarpal joint. The little finger can be hypoplastic or fully ...
Brachyphalangy of the distal phalange of the thumb. This condition is caused by either fusion or early closure of the phalange's growth plate. One example is brachydactyly type D, which is caused by an early closure of the thumb's distal phalange, leading to a congenitally short thumb with a similarly short and wide thumb nail.
Brachydactyly (from Greek βραχύς (brachus) 'short' and δάκτυλος (daktulos) 'finger') is a medical term denoting the presence of abnormally short digits (fingers or toes) at birth. The shortness is relative to the length of other long bones and other parts of the body. Brachydactyly is an inherited, dominant trait.
Didactyly (from Greek δι-di-'two') or bidactyly is the condition of having two digits on each limb, as in the Hypertragulidae and two-toed sloth, Choloepus didactylus. In humans this name is used for an abnormality in which the middle digits are missing, leaving only the thumb and fifth finger, or big and little toes.
