Abstract :

Background: Evaluation of GA using ultrasound is based on measuring one parameters of the fetus. HL used to give a good GA estimate,. The present study was determining gestational age by USG GA of humerus length and it’s correlated with LMP gestational age in central Indian population. Methods: This was an observational cross sectional study conducted in the Department of Radiology in collaboration with Department of Anatomy at L.N. Medical College and Research Centre, Bhopal. A total size of 200 pregnant women, targeting 5 – 40 weeks of gestation shall be considered.A straight measurement of length is determined from a sagittal line between 2 points at each end of the bone shaft; three or more measurements were taken in each examination, disregarding any curvature. Results: The correlation between 2nd and 3rd trimester LMP & humerus length gestational age, which is found to be highly correlated and it is statically significant (P value – 0.01). Conclusion: It can be concluded from the result that the length of the humerus is the best parameter for assessing the gestational age in the 2nd trimester. HL is less accurate than other fetal parameters for estimation of GA followed by BPD, HC in the 3rd trimester.
