Term ID: 9637
Name: Absent proximal phalanx of thumb
Synonym: Absent innermost thumb bone; Absent ossification/absent proximal thumb phalanx; Aplasia of the proximal phalanx of the thumb
Definition: Absence of the proximal phalanx of the thumb. 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.
