KOSIF, Rengin; DIRAMALI, Murat  e  SERTEL, Seda. Distances of Palmar Flexion Creases (Haustra Digiti) and Digital Formulae in Right and Left Handed People. Int. J. Morphol. [online]. 2015, vol.33, n.1, pp.173-177. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022015000100028.

Digital flexion creases are one of the external anatomical landmarks in the hand. In this study, we measured and compared the distances between the digital skin creases (haustra digiti) in the fingers of right-handed and left-handed individuals. We also recorded the digital formulae. No significant difference was detected between left and right-handed females and left and right handed males on distance of skin creases (p>0.05). No difference was detected on haustra digiti of the right handed females their own hands. Females who use their left hand had a significantly longer(p=0.48) distal haustra digiti segment on their right second finger than that of their left hand. However, no significant difference was detected between male individuals on their left and right hand all haustra digiti segments. The rate of hand digital formulae of 3>4>2>5>1 was 78.12% in left-handed females, 66.7% in left-handed males, 54.54% in right-handed females, and 78.57% in right-handed males. Our study has contributed to the literature on the morphological asymmetry of left-handed females.
