✦ Synopsis

Using ultrasound measurements of the femur, tibia, humerus, radius (N = 515), and fibula and ulna (N = 385) from normal fetuses between 12 and 40 completed weeks of gestation, growth models were determined for each bone by computer analysis. On the basis of residual analysis, growth of fetal limb bones could best be expressed as a function of tangens hyperbolicus. Growth profiles and growth data are shown with 5th, loth, 50th, 90th, and 95th percentiles. These results are compared with previous investigations of limb bone measurements.

Quantitative characterization of fetal growth requires the selection of measurement parameters and a growth curve model. For such studies we propose two new parameters (the head cube and the abdominal cube) and a new growth curve model [P = c(t)k+s(t)]. These parameters are relatively insensitive to

Growth of the fetal abdomen has been reexamined in a longitudinal study of 32 normally growing fetuses using the abdominal profile area (AA) and the Rossavik growth model.
