![]() A short femur diagnosis in a fetus with an otherwise normal follow-up determines just a higher risk of being small (SGA or IUGR). According to ROC analysis, FL measurement behaved as a good diagnostic test for SGA and IUGR. Conversely, none of them presented Down's syndrome or skeletal dysplasia. SGA, IUGR, and AUD were more frequent in the fetuses with short femur. Finally, ROC curves were drawn in order to evaluate the FL diagnostic ability for the conditions appearing with increased frequency. To assess fetal outcome, the frequency of SGA, IUGR, abnormal umbilical Doppler (AUD), Down's syndrome, and skeletal dysplasia was determined for each group after delivery, and the relative risk in comparison with the control group was obtained. FL values were plotted with the curves representing Z-scores −2, −3, and −4. FL values were converted into Z-scores and classified into 4 groups: control group: Z-score over −2, group 1: Z-score between −2 and −3, group 2: Z-score between −3 and −4, and group 3: Z-score below −4. 156 fetuses with isolated short femur were compared with a control group of 637 fetuses with normal femur length. To assess the outcome of fetuses with isolated short femur detected at 19–41 weeks and determine to what extent this incidental finding should be a cause of concern in fetuses with a normal previous follow-up.
