Ultrasound identification of the fetal hand must first be undertaken and then appropriate magnification accomplished. The evaluation requires stretching of the 5 fingers. The diagnosis is established when the middle phalanx of the fifth finger is markedly smaller than normal or absent, which often causes the finger to be curved inward (PMID:16100637).
