ABSTRACT
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.
RESUMEN
Los pliegues digitales de flexión constituyen unos de los puntos de referencia anatómicos externos en la mano. En este estudio se midieron y compararon las distancias entre los pliegues digitales de la manos (haustra digiti) de individuos diestros y zurdos. También se registraron las fórmulas digitales. No se detectaron diferencias significativas entre mujeres zurdas y diestras y tampoco entre varones diestros y zurdos en relación a la distancia de los pliegues digitales (p>0,05). No se detectaron diferencias en el haustra digiti de las mujeres diestras. Las mujeres que utilizaban su mano izquierda tenían una diferencia significativamente mayor (p=0,48) en el segmento distal del segundo dedo, comparado con el de la mano derecha. Sin embargo, no se detectaron diferencias significativas entre los individuos de sexo masculino en sus manos izquierda y derecha, a nivel de todos los segmentos de los haustra digiti. La fórmula digital 3>4>2>5>1 se encontró en 78,12% de las mujeres zurdas, en el 66,7% de hombres zurdos, en el 54,54% de mujeres diestras, y en el 78,57% de hombres diestros. Nuestro estudio ha contribuido a la literatura sobre la asimetría morfológica de los pliegues digitales de las mujeres zurdas.
