Abstract
The developmental feature of the shoulder joint in
the middle and later stages of the fetal period has been
studied by means of morphological measurements on
the various constituents of the right shoulder joint , such
as; articular capsule , articular fossa, glenoidal labrum,
proximal part of the long head of the biceps brachii
muscle , glenoid fossa of the scapula, and the upper
end of the humerus. The materials used for present
observation are 365 cases including 181 cases of male
and 184 cases of female of the Korean fetuses aged
from the 4th month to the 10th month.
1. The longest measurement has been made on the
posterior part of the joint capsule , while the shortest
one on the anterior part of the joint capsule.
An equal lengths have been measured on the upper
and lower surfaces of the capsule. A relatively
rapid lengthening is detected on the anterior part
of the capsule, is followed by those on posterior
part, lower part, and upper part, successively,
with gradual decrease of the velocity of the growth
with the time. The range of the growth of the
upper part is comparable to that of the body
length.
2. Twice of value has been measured on the width
of the proximal tendon of the long head of the
biceps in comparison with that of the thickness of
the biceps. The growth on the thickness is more
rapid than that of the width.
3. The supero-inferior diameter of the articular fossa
of the joint is longer than the transverse diameter
of it. The width-height index at the 4th month
is about 72( %), and is comparable to that of the
adult. A relatively broad and shallow articular
fossa in the middle fetal stage is gradually replaced
to the relatively narrow and deep one with the
time.
4. Of the glenoidal labrum well developed upper
paπ is observable in comparison with those of
the remainder parts.
5. Of the glenoid fossa the supero-inferior diameter
is shown a relatively rapid increase, whereas, the
slow one for the transverse diameter of it.
6. Of the head and anatomical neck of the humerus
the supero-inferior diameter is shown by a relatively
rapid multiplication with the time , while , the
relatively slow one for the antero-posterior diameter.
7. On the growths of most of the items a relatively
rapid increase is observed until the 6th month,
and is followed by a relatively slow one thereafter.
8. The proportions of the several mean values from
the 10th fetal month over those of the adult are
distributed within 24. 0-26. 6% in male and 28. 8
-31.6% in female for the glenoid fossa of the
scapula, and 37.9-38.8% in male and 42.3-44.
2% in female for the upper end of the humerus.
9. Significant difference has not been found between
the male and female sexes.
