Abstract

OBJECTIVE
The purpose of this study was to analysis the medial longitudinal arch of the foot with simple radiography METHOD: We reviewed 387 feet of 219 patients with no deformity who took weight-bearing foot simple radiography. Foot length, length from talonavicular joint to posterior heel (TN), length from cuneonavicular joint to posterior heel (CN), length from cuneiform-metatarsal joint to posterior heel (CM) were measured with the digital imaging and communication in medicine (DICOM) files of the picture archiving communication system (PACS) (PiViewSTAR(r), INFINITT, Korea). RESULTS: There was significant correlation of foot length and relative location of joints of medial longitudinal arch. In males, relative value to foot length of TN, CN, CM was 39.86+/-0.97%, 45.97+/-1.20%, and 57.12+/-1.15% respectively. In females, relative value to foot length of TN, CN, CM was 39.41+/-1.19%, 47.12+/-1.44%, and 56.51+/-1.37% respectively. There were significant differences between men and women for location of joints of medial longitudinal arch. CONCLUSION: Location of joints of the medial longitudinal arch of the foot can be given a numerical value.
