Abstract

In order to induce the equation formulae for the estimation of total upper extremity length from the measurements of the lower extremity. authors meas· ured the 2,100 Korean fetuses ranging from 16 to 36 weeks in age. and the following couc1usions have been drawn. 1. The correlation coefficients of over 0.9 between the total upper extremity length and the measurements of the lower extremity were indicative of highly correlated condition. 2. Accordingly. the equation formulae for the estimation of total upper extremity length from the measurements of the lower extremity could be figured out as Tables 8 and 9 (single measurement) and Tables 12 and 13 (double measurements). 3. Differences of approximately lmm in male and 2mm in female were manifested between actual and estimated total upper extremity lengths, where the estimations were based on single measurement. 4. Differences of approximately lmm in male and 2mm in female were manifested between actual and estimated total upper extremity lengths. where the estimations were based on double measurements. 5. The estimated total upper extremity lengths from single and double measurements were closer to actual one in same degree.
