한국인태아 고관절발육에 관한 연구

Abstract

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.
