What Is the Obturator Sign?
A pair of large oval holes surrounded by the pubic and ischial branches before and below the human pelvis. The obturator is closed by obturator membrane, but a thin tube is left, and nerves and blood vessels pass through the tube.

- form
- The pubic bone constitutes the anterior lower part of the hip bone, and it is divided into two parts: upper and lower branches. The body is composed of the anterior inferior part of the acetabulum 1/5. The upper surface of the bone at the junction with the zygomatic body is rough and raised, called the zygomatic humerus, thus extending the upper branch of the pubic bone forward and inward. . On the upper branch of the pubic bone there is a sharp ridge, called the pubic comb (pecten pubis), which travels backward on the arch line and finally reaches the pubic tubercle, which is an important body surface sign. The rough upper edge of the pubic tubercle to the midline is the pubic condyle, which can also be found on the body surface. The oval rough surface inside the upper and lower branches of the pubic bone is called the symphysial surface. The joint surfaces on both sides are connected by cartilage to form the pubic bone union. The inferior branch of the pubic bone extends backwards and downwards and is combined with the sciatic branch. In this way, the pubic bone and the ischium together form an obturator foramen.
