Studies on Morphological Development of Hip Joint of Korean Fetus in Middle and Later Stages of Prenatal Lif

The development feature of the fetal hip joint in, the middle and later stages of the fetal period has been studied by means of the anatomical measurements, 。n the various items, such as; the joint capsule, accessory ligaments, articular fossa, articular labrum, acetabulum, head of the femur, neck of the femur , and upper end of the femur. The materials used for present observation are the right hip joints from the 383 cases (190 cases of male and 193 cases of female) of the Korean fetuses aged from the 4th to the 10th month of the intrauterine life. 1. The growth of the various constituents paπicipating the hip joint is shown by a relatively rapid increment of the measurements with the time until the 6th month, and is followed by a relatively slow one thereafter. 2. A relatively rapid growth has been observed on the various measurements in comparison with that of the corresponding fetal body length except the thickness of round ligament of the femur head , the width of articular labrum, the width of the lunate surface of the acetabulum, and the anterior length of the femur neck. 3. The index drawn from trans-diameters on th ecross sectional area of the femur neck is higher than that of the adult. The higher index is supported by the fact that the supero-inferior diameter of the femur neck at the 10th month is still in underdeveloped' status in comparison with that of the other one

On the Ligamen t of Wrisberg of the Korean Fetus

A statistical analysis on the ligament of Wrisberg from the human fetus has been done by observing the shape and locality and calculating the incidence. The materials used for present observation are 383 cases of the knee joint from the Korean fetuses aged from the 4th month to the 10th month. It is found that about 97. 4 per cent of them are columnar in shape. The incidence for the ligament is 80. 4 per cent of the observed knee joints. The ligament is localized just behind to the posterior cruciate ligam' ent at 99.0 percent of the observed cases
