Determination of gestational age is important in civil and criminal cases. Though a reasonable assessment of gestational age can be made by measuring physical parameters such as crown-heel length, weight of foetus and by noting morphological features, organ development and appearance of ossification centres, an alternative parameter is desirable in some instances. In this study we directly correlate growth of different foetal hand parameters with gestational age. 30 formalin fixed human foetuses were obtained from Museum of Department of Anatomy, Jawaharlal Nehru Medical College, Aligarh. Foetuses were divided into five groups .(Group I :<17wks), (Group II : 17-20wks), (Group III : 21-25wks), (Group IV : 26- 30wks), (Group V : >30wks). We measured the seven parameters in the foetal hand i.e. length of the hand, breadth of the hand and lengths of the thumb, index finger, middle finger, ring finger and little finger. It was concluded that foetal hand, thumb and middle finger lengths are significantly correlated with gestational age and therefore these parameters could be utilized to estimate gestational age. This is justifiable in the medico-legal cases in which only hand or part of it is available for estimation of gestational age.
