The Vagina has a posterior point at which landmark?

The vagina’s posterior relationship is with the sacrum; the sacral base forms the posterior boundary of the pelvic cavity, and the posterior vaginal wall lies against it (with the rectouterine pouch just behind). The lateral sacral base is the bony landmark that best corresponds to this posterior vaginal point because it marks the posterior aspect of the sacrum that directly contacts the vagina. The other landmarks are distant from the vaginal lumen—inner thigh and IT band lie laterally on the leg/hip, and a point midway between the acetabulum and sciatic notch is a pelvic brim reference not at the posterior vaginal surface. Therefore, the posterior vaginal point aligns with the lateral sacral base.
