To clarify the correlations between the body height and maximum femoral length, we carried out orthoscanographic study in 187 normal adult Koreans (male; 80, female; 107). The results are as follws: 1. The average femoral length was 43.73±2.13cm for male, and 40.53±2.03cm for female. 2. The ratio of the femoral length to the height was 26.10±0.82% for male, and 35.91±0.77% for female. The coefficient of correlation was 0.78 and 0.80, respectively. 3. The regression equation was Y= −7.76+0.31X for male Y= −2.85+0.28X for female. (X: body height. Y: maximum femoral length)
