摘　　要：应用解剖测量、Ｘ线片结合髋臼形成指数对胎儿期髋臼发育进行了研究。结果显示胎儿后半阶段髋臼变浅，同时指出，只有在妊娠后半阶段，在子宫内产生一个不利于髋稳定的“机械力的改变”，就有利ＣＤＨ发生。Forty fresh fetal cadavers have been stud-ied.Degree of precision of 0.02mm has beenused for survey of the acetabular develop-ment,including the index of acetabular formand the percentage of prossessing circle area.The results demonstrated that the acetabulardepthin the late half period of fetus is shal -lower than that of first half period.They com-paring with Railes, the shallowness happenstwo months earlier,This study shows that ac-etabular depth is sufficiently enough to coverthe femoral head throughout the fetal periodhence the hip might be quite stable,even theacetabulum is shallower in the later half of fe-tal life. The data was evaluated for possible e-tiology of congenital dislocation of hip. It wassuggested that the growing up fetus and new-born with shallower acetabum might be thecause in developing dislocation of the hip inaddition to the continual mechanical force un-dercertain unfavorable posture.
