- The indices were determined by measuring 15 items in
365 fetal sacra and the following conclusions have been
1). The growth rates of the sacrum and the sacral arc
are a little higher than that of the stature and it corresponds
with the result in the fetal pelvis.
2). The growth rate of the greatest height of the
sacral arc is much higher than that of the stature and
it means the rapid formation of the curvature.
3). The growth rate of the sagittal diameter of the
sacral canal is much higher and that of the transverse
diameter is a little higher than that of the stature and
it means the change of the form of the entrance of the
sacral canal from flat anteroposteriorly to oval transversely.
4). The growth rates of the length of the auricular
surface, the transverse diameter of the sacral base and
the breadth between the lst sacral foramina are a little
higher than that of the stature and those of the breadth
of the auricular surface, the sagittal diameter of the
sacral base and the thickness of the 1st sacral vertebra
are still higher than those of the formers and it means
the change of the form of the sacrum from strong flat
to weak anteroposteriorly . OS). No differences are found in all of the indices
between both sexes.
