This study was conducted to evaluate different hair patterns on the dorsal aspect of phalanges of both hands and compare it between males and females.
Materials and methods: The present study was carried out in 300 undergraduate medical students (males and females 150 each) of Nepalgunj Medical College, Nepalgunj, Nepal. Distribution of phalangeal hair was observed by using hand lens under adequate light. Data was collected on proximal, middle and distal phalanges according to modified scheme of Burnstein classification.
Results: Statistical analysis showed that there was significant difference (p=0.000) in the average value of different patterns in distribution of hair on proximal phalanges of both hands. The most common pattern between both sexes is 1-2-3-4-5 (67%) but frequency is slightly less in females (56%) as compared to males (78%). In case of middle phalanges, result showed that there is significant difference (p=0.665) in the average value. The most common pattern between both the sexes is 3-4-5 (23%). Result also revealed that hair on middle phalanges is absent in 53.33% female and 35.33% males.
Conclusion: This study was carried out using standard anthropometric method. Hence, this result is useful because of their anthropological significance and is recommended to forensic experts in deciding sex, nationalism and race.
