How to measure pelvis

A woman's pelvis is different from a man's and has different meanings. When a woman gives birth, if the pelvis is too small, it will lead to dystocia, while the pelvis itself is too wide and easy to leak urine. The pelvis can be measured Next, let's talk about how to measure pelvis.

How to measure pelvic width

Pelvic width is too wide or too narrow. How to measure the width of pelvis?

Measuring pelvic width requires a soft ruler and special measuring tools. When measuring, the pregnant woman lies on her back on the flat bed, her legs are bent, her knees are supported by her hands, so that her thighs are close to the abdominal wall and her hips are raised, which is convenient for examination. The doctor puts on gloves, puts the index finger and middle finger into the vagina, and can touch the position of the sacrum, and then measures each diameter line with a special measuring tool. It can measure the diagonal diameter, the diameter between ischial tubercles and the transverse diameter of pelvic entrance. In order to know whether the fetus has dystocia. If it is estimated that the fetus is too heavy and the pelvis is too small, caesarean section is needed.

The size of pelvis is related to everyone's congenital genetic factors. Some people have large pelvis, while others have small pelvis, which is also related to acquired growth and development factors. In addition, the size of pelvis is related to everyone's height, and there is no uniform standard. Generally, when standing, when your hands are relaxed and drooping naturally, it is the best body shape when you just touch the pelvis. If the pelvis touches the arm in a large area, but there are no other symptoms clinically, the pelvis accounts for a large proportion, and vice versa. This is normal and there is no need to worry.

How to measure pelvic dimensions

It is necessary to check the pelvic size during pregnancy or postpartum, so how to measure the pelvic size is better?

Ma Bao wants to know how big their pelvis is. They can measure it by their own touch. The posture with hands akimbo is downward. On both sides of the body, you can feel some curved bones, called ilium. They go down, commonly known as the coccyx is the coccyx, and the part above the coccyx below the waist is the pelvis. Then touch the pubic bone above the private parts, and finally we sit down. When we sit down, we will feel that the most prominent bone is the ischium, and these parts that come into contact with it are probably the whole pelvic area. This is a simple way to measure pelvis at home.

For example, the anteroposterior diameter and oblique diameter of the pelvic inlet are used to evaluate the plane size of the pelvic inlet and judge the situation that the fetal head has just entered the pelvic bone; The anteroposterior and transverse diameters of the pelvic midplane are the narrowest of the three planes. The exit plane size judgment diameter line is the front and rear triangular sagittal line, and the exit front and rear diameter.

How to measure whether the pelvis leans forward?

Some people's hips are too upturned, which may be that the pelvis leans forward, so how to measure whether the pelvis leans forward?

Measurement method of pelvic inclination: the angle formed by the pelvic entrance plane and the ground plane when standing upright; The angle between the pelvic entrance plane and the vertical plane when lying down. The inclination of pelvic invasion during non-pregnancy is 50-55 degrees, which can be increased by 3-5 degrees in the third trimester. In general, the pelvic inclination between 60-70 degrees does not affect delivery. If the pelvic inclination is greater than or equal to 70 degrees, it is called excessive pelvic inclination. At this time, the sacrum often moves forward and upward, while the pubic arch moves backward and downward, which hinders the connection, descent and pronation of the fetal head. Cesarean section is often needed to terminate pregnancy.

You should know that people with forward pelvis will unconsciously roll up their legs when sitting in a chair, which is an obvious feature of people with forward pelvis. Pelvic forward tilt is particularly easy to cause people to trip when walking, and the soles of left and right shoes are worn to different degrees. In addition, people often feel depressed and yawn in life or study.

How to measure whether the pelvis is closed?

If the pelvis is closed, it will have adverse consequences. How to measure whether the pelvis is closed?

At present, there is no particularly good means to check whether the postpartum pelvis is restored and completely closed. However, the parturient can initially judge whether the pelvis has recovered through their own symptoms, especially in the third trimester of pregnancy and after delivery, many patients may have pubic separation.

Because the pelvis is close to delivery, in order to ensure that the pelvis is as large as possible and facilitate the smooth delivery of the fetus, the ligament will relax, leading to pelvic separation, especially pubic symphysis. This separation of pubic symphysis will cause severe pain in the pubic region of many patients, especially when they get up or change their posture. But with the extension of postpartum time, many people's pain can disappear on their own. When this kind of discomfort completely disappears, it can be preliminarily judged that the pelvis is basically closed.
