title: Prenatal origin of brachymesophalangia-5.
abstract: As shown in 91 embryos and fetuses in the 41-235 mm crownrump length, brachymesophalangia-5 may be identified in prenatal time. Although the ratios involving different combinations of length of mid-5 relative to other segments yield different frequencies of BMP-5, the short middle segment of the little finger is already associated with clinodactyly and developmental eccentricity as early as the ninth week of prenatal development.
