The index of the sciatic notch is smaller than that of adult male and larger than that of adult female and no change is found during above ranging period. 3). The angle of the sciatic notch is slightly larger than that of adult male and smaller than that of adult female and no change is found during above ranging period. 4). The anterior and posterior sides of the sciatic notch increase about 3 and 2.5 times respectively during above ranging period. 5). The anterior and posterior"segments of the sciatic notch increase about 3 and 2 times respectively during above ranging period. 6).
