Abstract
This inveitsgation is a study of several quantitative
growth changes in the skeletons of the Korean fetuses
between the fourth month of fetal age to term. The long
bones of the right upper extremity, such as humerus, ulna,
radius and the long bones of the right lower extremity,
such as femur, tibia, fibula of 391 fetuses (male 195,
female 196) were used for the materials. The total length,
diameters of the diaphysis and the length of the calcified
part of the diaphysis were measured and the monthly
average of the measurements, the monthly increment,
the monthly increment ratio, the monthly increment coefficient
and several indices were calculated. We could
present the growth changes of these fetal long bones.
. 1. The monthly averages of the total length, diameters
of the diaphysis and the length of the calcified part
of the diaphysis of the fetal long bones were presented.
2. The growth of the fetal long bones was more rapid
before the sixth month of fetal age and thereafter became
gradually slow.
3. The growth of the calcified part of the diaphysis
was rapid until the sixth or seventh month of fetal age
and thereafter became gradually slow but its growth rate
was· higher than that of the body stature and the total
length of the bone.
4,. The growth rate of the long bones of the upper
limb was lower than that of the body statare but the
growth rate of the long bones of the lower. limb. was
higher than that of the stature.
5. The absolute length of the long hones of' the
upper limb of the tenth month fetus was about 27-28%
of the adult lor g bones and the absolute length of the
long bones of the lower limb of the tenth month fetus
was about 2296 of the adult long bones, so the long
bones of the upper limb of the fetus developed relatively
more rapidly than that of the lower limb.
6. There was no significant sexual difference for the
fetal long bone growth.
