OBJECTIVE: To describe the relationships between gestational age and ultrasonographic measurement of fetal foot length.
STUDY DESIGN: A total of 462 ultrasonographic measurements were performed to describe the relationship between gestational age and fetal foot length at the Zekai Tahir Burak Woman Health Education and Research Hospital. The nomogram of fetal foot length versus gestational age between 15-42 weeks was constructed from the fetuses of healthy singleton pregnancies. All patients had normal ongoing pregnancies and known last menstrual periods.
RESULTS: A significant correlation was found between fetal foot length and gestational age (r = 0.890, p < 0.0001). Our results suggested that fetal foot length was a reliable marker for use in the assessment of gestational age.
CONCLUSION: This parameter is particularly useful when other measurements do not accurately predict gestational age, for example, dysplastic limb reduction and abnormal fetal head structure.
