Term info
Complete duplication of the distal phalanges of the hand
- Complete duplication of the outermost bones 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 accessory bone appearing in the proximo-distal axis on x-rays, is actually a different entity called a pseudoepiphysis (see corresponding terms), sometimes also referred to as hyperphalangism.
