ResumoA number of indirect methods of estimating the height of the medial longitudinal arch of the foot have been devised.1 The efficacy of the arch index as a valid and convenient predictor of arch height has been questioned.2 In this study, arch index was measured in 45 elderly subjects and navicular height was measured from weight bearing radiographs. Normalized navicular height was determined by dividing navicular height by foot length as measured from radiographs. A correlation coefficient of r=0.67 was found between navicular height and arch index. The correlation coefficient between arch index and normalized navicular height was found to be r=0.71. Arch index thus provides a simple quantitative means of assessing the height of the medial longitudinal arch with the limitation that only half of the variance in arch height can be explained.
