Ultrasonic evaluation of fetal limb growth: part II.

Abstract
The length of the ulna, radius, tibia and fibula was measured in 220 normal [human] fetuses. Computerized curve fitting provided normal values of bone length for age and biparietal diameter. Ratios of the length of the different bones are presented. Possible applications of these measurements include in utero diagnosis of fetal dwarfism, limb malformations, microcephaly, determination of gestational age, archeological dating of fetuses and forensic applications.
