Abstract

In order to induce the equation formulae for the estimation of total lower extremity length from the measurements of the upper extremity, authors meas· ured the 2,100 Korean fetuses ranging from 16 to 36 weeks in age, and the following conclusions have been drawn 1. The correlation coe뻐cients of over 0.9 between the totallower extremity length and the measurements of the upper extremity were indicative of highly correlated condition 2. Accordingly, the equation formulae for the estimation of total lower extremity length from the measurements of the upper extremity could be figured out as Tables 8 and 9 (single measurement) and Tables 12 and 13 (double measurements). 3. Di fferences of approximately 1mm. in both sexes were manifested between actual and estimated total lower extremity lengths, where the estimations were based on single measuremen t. 4. Di fferences of approximately 1mm. in both sexes were manifested between actual and estimated total lower extremity lengths. where the estimations were based on double measurements. 5. The estimated total lower extremity lengths from single and double measurements were closer to actual one in same degree.
