한국인태아 슬관절발육에 관한 연구

Abstract

The developmental feature of the knee joint in mid· die and later stages of the prenatal life has been analysed by means of the anatomical measurements on the 54 items including the accessory ligaments, the menisci and the participating bone ends from a sum of 382 cases (189 cases of male and 193 cases of female) of the Korean fetuses aged from the 4th to the 10th month of the prenatal life. 1. By the 4th month the medial collateral ligament is longer than the lateral collateralligament. The lateral ligament shows a relatively rapid growth by the 6th month, and at the 10th month it shows the highest value of the growth rate among the measurements of the present series (6.0). 2. The anterior cruciate ligament is longer than the posterior ligament throughout the period of the persent observation, and shows relatively rapid growth after the 6th fetal month. 3. By the 4th month the dimension of the medial meniscus is larger than that of the lateral meniscus. The similar relationship has been observed between the hollow areas occupied on the center of each of both the medial and lateral menisci. 4. Throughout the period of relatively regular pro' portional rates are detected on the measurements of the participating bone ends. 5. Of the medio-lateral (width) and antero-posterior
