Term ID: 9986
Name: Complete duplication of the phalanges of the 5th finger
Synonym: Complete duplication of the little finger bone; Complete duplication of the pinkie finger bone; Complete duplication of the pinky finger bone
Definition: A complete duplication affecting one or more of the phalanges of the 5th finger. 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.
