Abstract


The development of the hip joint was studied histologically and mathematically. The materials consisted of 129 human fetuses ranging from 9㎜. to 400㎜. crown-rump length.
1. The measurements revealed that height of the remoral head and the depth of the acctabular fossa increased gradually with advancing fetal age and the growth rates of both structures were found to be proportional to each other, although slightly increased size of the acetabular fossa at term.
2. The torsion of the proximal end of the femur and neck-shaft angle generally increased with advancing age.
3. The skeleton of hip joint consisted largely of condensed blastemal tissue in 9㎜. The acetabular fossa was indicated in the 23-25㎜. The hemoral head and acetabulum finished chondrification in the 23-25㎜.
The foves capitis femoris and both trochanters appeared by 40-45㎜. Ossification centers were first seen in th femoral shaft at 45㎜. the ilium at 55㎜. ischium at 100㎜. and the pubis at 120㎜. Ossification was spreading in two directions, inferiorly toward the triradiate zone and anteriorly anterior inferior iliac spine. Later, ossification spreads laterally toward the limbs.
4. Homogenous interzones and thress layered interzones in the hip joints were present at 16-20 ㎜. and 25㎜. respectively. The intermediated layer was continuous with the adjacent synovial mesenchyme in which capillaries appeared by 40㎜, Initial joint cavity was present around the periphery of the joint at 40㎜. and its complete formation at 60 ㎜ was noticed.
5. Primordia of the muscles and extra articular capsule were found at 25㎜. and at 42 ㎜. the latter showed initial capsular architecture.
From this results, it may be concluded that during the development of the hip joint height of the femoral bead and the depth of acetabular fossa in(reased without any marked change i their relative size, which might indicate that the congenital dislocation would not occur in uterice life of the fetus.
