Name:
Complete duplication of the proximal phalanges of the hand
Synonym:
Complete duplication of the innermost bones of the hand
Definition:
A complete duplication affecting one or more of the proximal phalanges of the hand. 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.
