Abstract
Objective : To sonographic correlation fetal foot length as a reliable parameter for estimation of gestational age in 2 nd and 3 rd trimester. Study Design : An analytical cross-sectional prospective study was performed. Settings : The study was performed in Meer Children and family clinic, Tajpora Lahore. Period: An analytical cross-sectional study was conducted from 15 October, 2021 to 15 January, 2021. Material & Methods : The present study is conducted in the in the Meer Children and Family Clinic Tajpura Lahore .In pregnant women attending the OPD during 2 nd and 3 rd trimester for routine checkups. The present study done in 60 normal pregnant women who were sure about their last menstrual period, have regular menstrual cycle, not experienced any vaginal bleeding. Ultrasonographic fetal foot length measurements was done without previous knowledge of gestational age and then the gestational age confirmed by biparietal diameter, abdominal circumference and head circumference . Results : The present study is conducted in 63 pragnent women between 15 to 35 weeks of gestational age attending the OPD for 2 nd and 3 rd trimester routine checkups the in the Meer Children and Family Clinic Tajpura Lahore . Sonographically we calculated foot length from 15 to 35 weeks of gestation. In our study to Early age at which fetal foot length could be seen and measured sonographically was found to be 15 weeks of gestation age. In 27 weeks of gestational age and mean foot length 83.67 with std. deviation 5.718 and std. Error Mean -720 and the mean value of foot length by gestational age is 93.33 with std. deviation and std. error mean 338.740 and 42.677 respectivly. Along with foot length bipraietal diameter(BPD),Abdominal circumference(AC),head circumference(HC) also measured for comparison. Conclusion : In the normal growing fetus the fetal foot length increases with increasing gestational age. Fetal foot length is a good parameter for gestational age especially in cases of femur achondroplasia, dolichocephaly or brachycephaly and in cases who are not sure about their L.M.P. Fetal foot length is used as an investigational implement to measured of gestational age in the late second and third trimesters of pregnancy. Fetal foot length was especially useful when other parameters did not correctly estimate gestational age, e.g., in cases of short-limb dwarfism hydrocephalus or anencephaly.

Highlights
In obstetrical, the growing age of a fetus, normally found on the assume first day of the last normal menstrual cycle . in embryology, this term is access as gestation does not start till fertilization of an oocyte happen around the middle of the menstrual cycle
Gestational age is a determine by the age of a pregnancy which is taken from the start of the woman's last menstrual period (LMP)
This study was done on 63 women with normal singleton gestations having regular menstrual cycles and known LMP to find accuracy of ultrasound in estimation of gestational age by foot length
Summary
The growing age of a fetus, normally found on the assume first day of the last normal menstrual cycle . in embryology, this term is access as gestation does not start till fertilization of an oocyte happen around the middle of the menstrual cycle. The growing age of a fetus, normally found on the assume first day of the last normal menstrual cycle . In embryology, this term is access as gestation does not start till fertilization of an oocyte happen around the middle of the menstrual cycle. GA is measured using the first day of the last menstrual period (LMP), which suppose that ovulation occurs on day 14 of the menstrual cycle.[1]. Accurate assessment of gestational in all is not possible infants which is newborn mostly when they are not well and need throughout care support. Gestational age is important for prediction of morbidity, mortality and further management.[2] Ultrasonography may be used to estimate gestational age. Accurate determination of gestational age is become important later in pregnancy for the management of obstetrical conditions such as postdate pregnancy preterm labor,intrauterine growth restriction.
