Term ID: 9614
Name: Bifid proximal phalanx of the thumb
Synonym: Notched thumb bone
Definition: This term applies if the proximal phalanx of the thumb is partially duplicated. 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) to a partially fused appearance of the two bones. In contrast to the proximal phalanges of the digits 2-5, the proximal phalanx of the thumb is embryologically equivalent to the middle phalanges of the other digits, whereas the first metacarpal is embryologically of phalangeal origin and as such equivalent to the proximal phalanges of the other digits.
