Abstract

The estimates of age based on measurements of humerus length (HL) can be used as an alternative in pregnancy dating. These additional measurements taken provide a more ‘universal view’ of the foetal development than can be afforded by any single measurement. In the present study humerus length was measured to study the correlation and significance of this parameter with last normal menstrual period (LNMP) in estimating the foetal gestational age [FGA]. Material and Methods: In the present study, a total of 100 antenatal women attending Out-Patient Department of Obstetrics and Gynaecology at Government Maternity Hospital, Sultan Bazaar, during the period of January 2016 to August 2016 i.e. for eight months were included in the study, undergone ultrasonography of parameters of humerus bone. Result: HL and LNMP value in Total estimating the FGA with correlation coefficient r value of 0.951, correlation was significant at < 0.01 level (p value 0.000). In second Trimester r value of 0.885, and correlation was significant at the 0.01 levels (p value 0.000) and < 0.01 level (p value 0.000). In 3rd Trimester r value of 0.621 and correlation is significant at < 0.01 level (p value 0.000). Coefficient r-value, of humerus HL was 0.961, in the study population trimester wise. Conclusion: We concluded that ultrasonographically measured HL of the foetus is reliable predictor in estimating the foetal GA.
