Term ID: 9612
Name: Duplication of the distal phalanx of the thumb
Synonym: Double thumb distal phalanges; Duplicated terminal phalanx of thumb; Duplication of distal thumb phalanx; Duplication of terminal thumb phalanx; Duplication of the outermost bone of the thumb; Partial/complete duplication of the distal phalanx of the thumb
Definition: Complete or partial duplication of the distal phalanx of the thumb. Depending on the severity, the appearance on x-ray can vary from a notched phalanx (the duplicated bone is almost completely fused with the phalanx), a partially fused appearance of the two bones, or two separate bones appearing side to side.
