Human Pelvis Development
Carnegie Stage Event
18 chondrification centres of the ilium, ischium, and pubis first appears. Located around the acetabulum and grew radially.
20 iliac crest formed while the iliac body's central part remained chondrified.
22 Sacroiliac joint forms.
22 Iliac body is discoid. The growth rate was greater in the ilium than in the sacrum-coccyx, pubis, and ischium.
23 Articulation of the pubic symphysis, connection of the articular column in the sacrum, and Y-shape connection of the three parts of the hip bones to the acetabulum.
Early Fetal connection of the ischium and pubic ramus.
Data from human CT and MRI study.[1]
