Why do girls have anterior pelvic tilt?

The bone structure of the human body is the same, but the bones must be in a normal position to represent health. If the upper pelvis of the human body protrudes forward, the health will be affected to a certain extent. In order to better avoid this situation, let's understand why girls have anterior pelvic tilt?

1. Caused by incorrect posture: The main reason why girls have pelvic tilt is that the center of gravity is not in the normal position when they stand up and walk. Instead, the center of gravity is moved to the intervertebral disc bone. As a result, the body can only maintain its balance by rotating the pelvis, which causes the pelvic tilt.

2. Caused by muscle abnormality: If the body's muscles are too tight or too loose and weak, it may also cause girls to have pelvic tilt anteriorly. This is because such factors will cause the pelvis to lose its normal antagonistic muscle function to inhibit balance, and under the influence of muscle abnormalities, the abnormal phenomenon of pelvic tilt anteriorly will occur.

3. Traumatic causes: If you suffer some trauma in your daily life, such as sprained waist, ligament sprain, etc., it may also cause pelvic tilt. In this case, you must see a doctor immediately for an X-ray examination to determine the state of pelvic deformation and take immediate corrective measures.

Pelvic measurement standard

In clinical medicine, external pelvic measurements are generally carried out first, that is, the standard value of the anterior superior iliac spine diameter is 23-26 cm, the standard value of the iliac crest diameter is 25-28 cm, the sacropubic external diameter is more than 18.5 cm, the standard value of the greater trochanter diameter is 28-31 cm, the standard value of the ischial tuberosity diameter is 8.5-10 cm, and the pubic arch angle is greater than or equal to 90 degrees.

If any or all of the external pelvic diameters are abnormal, accurate internal pelvic measurements should be performed during labor, and a normal delivery method should be selected based on fetal size, fetal position, and labor force. If any or all of the external pelvic diameters are abnormal, accurate internal pelvic measurements should be performed during labor, and a normal delivery method should be selected based on fetal size, fetal position, and labor force.

Pelvic measurement is now quite common. It is an important indicator to determine whether a natural birth can be chosen. Pregnant women are advised to measure it accurately before delivery to avoid panic during delivery.
