Volar Digital Transverse Creases of the Nigerians

Abstract

The volar transverse creases of the second to fifth fingers have been shown to be genetically influenced and not caused primarily by embryonic flexion movements.  The presence of extra, displaced and missing volar digital transverse creases in individuals with normal joint anatomy may reveal abnormalities.

This study aims at documenting the prevalence patterns of volar digital transverse creases of digits II-V in the normal Nigerian hands.

Volar digital transverse creases of the digits II-V of 303 male and 168 female Nigerians were studied using palm prints obtained by ink method.

Single crease (M) had highest frequency in the distal crease, followed by proximal crease and then middle crease. Double crease (D) frequency was highest in the middle phalanx, followed by proximal crease and then distal crease. Triple (T) frequency was highest in the middle phalanx; it was not common in the proximal and distal phalanx. Frequency of E and E⁺ creases were common in the middle phalanx, followed by distal phalanx and less common in the proximal phalanx.

No differences exist between male and female digital creases of Nigerians, there is reduced frequency of the crease types T, E and E⁺ in all the fingers of male and female, and the male fingers II-IV showed absent E and E⁺ in the proximal phalanx.
