Complete duplication of thumb phalanx (HP:0009943)help
Term ID: 9943
Name: Complete duplication of thumb phalanx
Synonym: Complete duplication of the phalanges of the thumb; Complete duplication of thumb bones; Digitalization of thumb; Digitalization of thumbs
Definition: A complete duplication affecting one or more of the phalanges of the thumb. As opposed to a partial duplication were there is still a variable degree of fusion between the duplicated bones, a complete duplication leads to two separate bones appearing side to side (radio-ulnar axis) as seen on x-rays. A duplication leading to an accesory bone appearing in the proximo-distal axis on x-rays, this is actually a different entity called a Pseudoepiphyses (see according terms) sometimes also referred to as Hyperphalangism.
