Hip dysplasia: causes and treatments

Hip dysplasia is a congenital disorder, that is, it appears at birth. This disorder affects the hip joint. It has an incidence of one in every 1000 live births.

In normal situations, the hip is formed as a ball and cup joint. When a person is born with hip dysplasia, the cup is usually shallow. In this way, it allows the ball-shaped area of ​​the femur to slide in and out of the cup. Thus, the "ball" can be partially or totally removed from the cup.

On the other hand, mention that the majority of people suffering from this congenital disorder They are usually first-born and female babies. Family history with hip dysplasia favors the development of this problem.

Causes of hip dysplasia

Hip dysplasia, therefore, It is a situation in which there is an alteration of growth at the level of anatomical structures, including the soft parts of the joint.

Today, this disorder is considered it is the consequence of eccentric pressures of the femoral head during the last month of pregnancy.

However, hip dysplasia is a disorder considered "multifactorial inheritance." With this term, experts refer to the congenital defect is determined by several factors, both genetic and environmental.

For example, one of the environmental factors that is believed to contribute to hip dysplasia is the baby's response to the mother's hormones during pregnancy.

A narrow uterus that does not allow fetal movement or a breech birth can also cause hip dysplasia. In addition, another fact to keep in mind is that the left hip is usually the worst stop. This is due to the position of the fetus inside the uterus.

Treatment for hip dysplasia

The goal of different treatments for hip dysplasia is get a reduced hip quickly and early in a stable and safe way.

After having achieved a reduction and restoration of the concentric pressure of the femoral head inside the acetabulum, the roof of this one ossifies and develops again, especially within the first two years of life, at which time dysplasia is largely reversible.

The indicated treatment will depend on several factors, such as if the dislocation is typical or teratogenic, the age or duration of the dislocation, among others.

Treatment from birth to six months

After the reduction, the second stage aims to preserve the physiological position. To do this, different devices are often used, the most used being the Pawlik harness.

This harness is a dynamic device that allows active hip movement within the safety zone. A) Yes, allows the normal development of the acetabulum and femoral head, as the hip moves in its reduced position.

The duration of treatment varies depending on the child. Once the treatment is finished, X-rays must be taken to check if the joint is developing correctly.

Treatment from six to eighteen months

This treatment is used. when the previous one has failed and in cases where the diagnosis has been later. Normally, treatment in this period of time is surgery. The fundamental factor in the treatment of hip dysplasia is to achieve a concentric reduction of the femoral head.

Once this is achieved, the second step is to maintain the reduction and improve the stability of the hip, being able to do so the realization of osteotomies (section or surgical cut of a bone). Among them you can differentiate several types:

  • Ilíaca de Salter.

  • Acetabular
  • Iliaca from Sutherland.
