title: Incidence, density and direction of hair on the dorsum of phalanges of the hands in Malays.
abstract: In this study 200 Malay subjects (100 males and 100 females) were randomly selected from patients attending outpatient clinics of Hospital USM, Kelantan, Malaysia, to find out the incidence, density and direction of hair on the dorsum of phalanges of the hand. These features have not been studied so far in females nor has such a study been conducted in Malays. The probability of density of hair distribution among the digits of both hands showed significant correlation on proximal phalanges (p < 0.05) in both sexes. Significant correlation was not observed, however, in the middle phalangeal hair (MPH) of the hands. The direction of proximal phalangeal hair, from little finger to the thumb, showed significant changes from ulnar to radial in both sexes (p < 0.05). Identification of isolated digits, which is of medicolegal importance, would be more accurate if the direction and the density of hair on the digits are both considered together. MPH was present in 48% of males and in 33% of females studied. Comparisons with presence of MPH in other populations show that Malays are ethnically similar to other Asiatic populations.
