Crown-rump length and sitting-height
Crown-rump length and sitting height measurements are often useful for children
with contractures of the lower body. These measurements will not correlate
directly with height or length, but can indicate a child's rate of growth
when plotted on CDC growth charts. Although the measurements will be below
the 5th percentile for age, they will show whether or not the child is following
a consistent growth curve.
