Symptoms of hip dislocation in children

We all know that children are particularly prone to ankle dislocation when they are young, because this part of the baby is very delicate, and often it may be dislocated due to some external reasons. At this time, the baby may limp. Mothers must take their children for treatment in time, and take a film if necessary. So what are the symptoms of hip dislocation in children?

The earliest symptom of hip dislocation is restricted abduction and external rotation of the hip. Parents can determine whether their children have similar symptoms through some observations.

First of all, you can judge whether there are any abnormalities by how the child learns to walk. If your child walks with a limp or sways from side to side like a duck, or if his or her waist protrudes forward when he or she stands, he or she may have a dislocated hip. Many parents mistakenly believe that this is a normal movement when their children are just learning to walk, and some even mistake it for a problem of bow legs or bow legs, thus delaying treatment.

Secondly, let the child lie flat on the bed, bend his knees to 90° first, and then slowly abduct the hips to see if he can lie flat on the bed. It is recommended to do a simple "frog test" examination after the child is born: flex the child's knees and hips, and spread the hip joint outward. If it spreads smoothly, it is normal. Otherwise, further examination in the hospital is needed.

In addition, you can observe whether the child's buttock lines and thigh lines are symmetrical, whether there is any popping or abnormal movement in the child's hip joints, etc. If any abnormalities are found, ask an orthopedic doctor to check and treat it as soon as possible.

There are also some children who suffer from a type of hip dislocation called developmental dysplasia of the hip and may not have typical symptoms such as lameness in the early stages.

For the diagnosis of hip dislocation in children, the attending doctor will first conduct an examination and observe the appearance of both lower limbs in a targeted manner. If the child is able to walk, his gait, walking posture, and the movement of his various joints should be observed. Some targeted examinations should also be done accordingly, such as the hip abduction test that we often talk about clinically, etc. In terms of instrumental examination, ultrasonic examination of the hip joint should be the preferred method for infants over six months old. The characteristic of ultrasound is that it can penetrate cartilage. When a child is less than six months old, before the ossification center of the femoral head appears, the femoral head is composed of cartilage. Ultrasound can penetrate it, allowing us to observe the shape of the femoral head and acetabulum very well.

Ultrasonic hip examination technology for diagnosing pediatric hip dislocation has been carried out in many countries and regions in the world, promoting the early diagnosis of pediatric hip dislocation and effectively reducing the late incidence and complication rate of pediatric hip dislocation. Therefore, early examination with ultrasound is very necessary.
