Introduction: An accurate determination of gestational age is must for Obstetricians and Gynecologists to make appropriate decisions, for identifying and counseling of women who are at risk of a preterm delivery. It is also essential to evaluate fetal growth and the detection of intrauterine growth restriction (IUGR). In our present study, we worked on fetal humerus length and found that in normal growing fetus, fetal it increase with advancing gestational age and regression analysis showed a strongly significant relationship between gestational age and fetal humerus length. The purpose of this study is to find out the other parameters such as foot length and tibial length which can be used to determine the gestational age or can be used in other conditions where the previous parameters are unreliable and can also be used as supplement in the diagnosis of many genetic defects.
Methods: 100 pregnant women underwent ultrasonographic measurements of humerus Length from 13 to 40 weeks of gestation during routine ANC, in the Radio diagnosis Department.
Results: In our study, we found the earliest age at which humerus length could be seen by ultrasound was 13 weeks of gestation and mean humerus length 13.12± 0.50, while at 40 weeks of gestation 69.00±00 respectively. A strongly significant relationship has been observed between fetal humerus length and gestational age by regression analysis.
Conclusion: Humerus length can be considered as one of the good parameter for the determination of gestational age.
