This pelvis model shows the woman's pelvis as well as the 2 lower lumbar vertebrae and part of the femur bones flexibly mounted with elastic.



The model is cast in the natural size of the pelvis, and the level of detail on the bones is good. The SI joint is assembled using elastics . The front joint (the symphysis) is also glued and consists of soft silicone. Below you can read more about the pelvic measurements in relation to the pelvis as a way of birth.


We sell fetal dolls, which are targeted for birth preparation. Our fetal doll with placenta (mother cake) and umbilical cord fits exactly to this pelvis model, so that the pelvis as a birth canal can be demonstrated with the doll.

Anatomical features

Anatomically, the model shows the female pelvis. Just like in men, the pelvis consists of the 3 building blocks, which are the 2 hip bones and the sacrum. The model also shows the 2 lower lumbar vertebrae. Overall, the model shows the following bones:

Os coxae (the 2 hip bones) of which both are composed
- Os ilium (iliac bone/hip bone)

- Os ischii (seat bone)

- Os pubis (pubic bone)



Us sacrum (sacrum) incl. os coccygis (coccyx)
4th and 5th lumbar vertebra (lumbar vertebra)
In the bone tissue, the most important details can be seen, such as large nodules. Smaller details such as the linea glutaea are omitted.





The pelvis as a birth canal

Normally the following 3 connection lines are specified:

- Conjugata vera (normally measures 11 cm in the female pelvis)

- Diameter obliqua (usually measures 12.5 cm in the woman's pelvis)

- Diameter transversa (usually measures 13 cm in the woman's pelvis)

On this pelvis model, the above measurements are respectively: 10.5 cm, 13 cm and 14.5 cm.

You can also use a measure for the anteroposterior exit from the pelvis, which is the distance from the symphysis to the tip of the coccyx. On this model, the distance is approximately 11 cm (but it depends on the position of the coccyx, as it is movable).
