Identification of human remains is an imperative element of any medicolegal investigation, and a challenging task for forensic experts and physical anthropologists worldwide. Three hundred adult hands (150 males and 150 females) belonging to south Indian population were studied to investigate sexual dimorphism of the index and ring finger ratio. The index and ring finger ratio is derived by dividing the index finger length by ring finger length. The index and ring finger ratio is found to be higher in females. Index and ring finger ratio ≤0.9700 identified 80% of males for both hands, and ratio >0.9700 identified 74% females for the right hand and 78% for the left hand accurately. This study may prove useful to determine the sex of an isolated hand when it is subjected for medicolegal examination.
