Dr. Libardi. To my knowledge there are no charts for fetal dating from sonographic hand measurements. However there have been some publications of fetal finger and phalanx measurements. Below is one such article, full article is available at the web site. The full article has graphs for each finger.
Hope you will post your images for us. Please let us know what you find out. Thanks Terry

Prenatal age-specific reference intervals for measuring all five digits of the fetal hand
J. Tovbin*, R. Maymon*, L. Tovbin?, E. Dreazen*, I. Bukovsky* and A. Herman*
"Sonographic visualization and measurements of all five fingers were obtained in all 302 cases without exception. However, it was possible to obtain a coronal section of all five fingers in a single plane in only 22% of the cases (mainly in weeks 14-19) (Figure 1). Two separate planes were needed in 57% of the examined fetuses, one sectioning fingers 2-5 and the other for the thumb. Three or more frames were needed for the remaining 21% of cases. The average time needed for an accurate measurement of all five fingers was 9.0 ± 2.0 min.
Linear growth of each of the five fingers was observed across the evaluated range of gestation (r2 = 0.86! for digits 1 and 2, r2 = 0.87 for digits 3 and 4 and r2 = 0.85 for digit 5, P < 0.001). The following equations for the measurement of the individual digits was applied:
mean length of digit 1 = ? 5.471 + 0.729 × gestational week;
mean length of digit 2 = ? 8.463 + 1.026 × gestational week;
mean length of digit 3 = ? 9.276 + 1.122 × gestational week;
mean length of digit 4 = ? 8.912 + 1.086 × gestational week;
mean length of digit 5 = ? 6.238 + 0.835 × gestational week.
Charts which depict the distribution across the gestational weeks of the measurements for each separate finger, are presented in Figure 2. The gestational age-specific reference interv! al of the 5th, 50th and 95th centiles for each of the five finger lengths throughout 14-27 gestational weeks are presented in Table 1."
