Background: Assessment of foetal femur growth parameters is one of the key - for estimation of foetal gestational age, and determination of population growth characteristics. The present study was to evaluate the relationships between the crown-rump length (CRL) and foetal femur growth parameters and the gestational age during the second and third trimesters.Material & Method: Fifty six dead normal spontaneously delivered foetuses of second & third trimester of pregnancy were collected from the department of Obstetrics & Gynaecology, Government Medical College and Hospital, Aurangabad. A total of eight parametric variables were obtained from bilateral femora using a sliding calliper. Obtained data were statistically analyzed by unpaired t-test and Pearson correlation coefficients.Result: There was no significant difference observed in growth patterns between the male and female during the second and third trimesters. A significant relationship between the studied foetal growth parameters and the gestational age was found. It appears that foetal CRL and femur growth parameters are accurate for the calculation of gestational age.
