Abstract

In recent times the modification and injury of foot are shown due to various activity. It is essential to have detailed knowledges about the anatomical structure of medial longitudinal arch of foot for doing orthodigita or making shoes to prevent variation of medial longitudinal arch of foot. This study aimed to measure the constitution and to suggest the index of medial longitudinal arch of foot. Fifty four feet (30 M/24 F) obtained from the collection of the Department of Anatomy and Cell Biology of College of Medicine, Hanyang University were studied. We measured the length of foot, the height of foot, and the first ray angle. Also, we found the index of medial longitudinal arch and compared this results with various races anthropologically. Each items was analyzed using SPSS win 13.0. The length of foot was 211.12+/-13.02 mm and the height of foot was 39.03+/-6.27 mm. There was statistically significant difference between the values of male and female and among the age groups (p>0.001). The first ray angle was 24.98+/-2.16 degrees. There was statistically significant difference between the values of male and female (p>0.001). The medial longitudinal arch index was 18.43+/-2.33. The date shows clear distinction between the value of index in this study and the American's value of index as a result of comparing races. The results of this study would be useful to clarify the characteristics of the medial longitudinal arch.
