The hip joint is an important hub connecting the human torso and lower limbs. The hip joint supports the trunk and the lower lower limbs. It is the most needed and most critical part of walking and sitting.
Asymmetry of the hip and thigh lines on both sides is a very common phenomenon. It is very unscientific to judge whether a child has a hip development problem simply by a hip pattern or a thigh pattern asymmetry!
If you find a similar problem, you should consult a professional child orthopedic surgeon and you may want to assist with the diagnosis by B-ultrasound or X-ray examination.
If you can find out, the sooner you treat, the better. However, under normal circumstances, the baby will also have asymmetrical hip pattern, so it is especially important to learn the correct method.
Observe the shape of the lower limbs of the newborn. If it is unilateral dislocation, we can see that the length of the groin on both sides of the groin is different, and the affected hip and thigh skin will increase and deepen.
(1) Let the newborn lie flat, put the two feet flush, the two squats close together, and then bend the knee about 90 °. If the knees are found to be uneven, it is caused by the upward displacement of the femur, and the high side is the dislocation side.
(2) Let the newborn be supine, make it knees and hips 90° (right angle), then hold the knees abduction. If it is normal, the outside of the knees should touch the bed surface, generally can be abducted 85° ~90° or so. If there is dislocation, you cannot touch the bed. If only abduction 50 ° ~ 60 °, it is positive, only abduction 40 ° ~ 45 ° is strongly positive.It is recommended to go to the hospital in time to film and then find a professional doctor to judge!
1. Some mechanical factors, such as excessive flexion of the fetus in the uterus or breech in the uterus (especially the breech position of the leg), and excessive force during the delivery of the midwife to pull the fetus's lower limbs, etc. disease.
2, the fetal position in the uterus is not normal, the hip joint is excessively flexed, and it is easy to cause the disease.
