What is subluxation of the hip joint?

Subluxation of the hip joint is an extremely common type of dysplasia, which is further subdivided into several types. Congenital dislocation (dysplasia) of the hip is a defect of the articular parts of bones that appear due to improper development and the resulting change in the position of the top of the femur.

Types of hip dysplasia

There are 3 types of dysplasia, subluxation, and dislocation previva. They also considered different levels of the same pathology.

Previlige is the instability of the immature joint, which has a chance a little later to develop in a normal state, or is a soil formed over time subluxation. But capsule is at this time elongates, causing the head changes its position and tucked into the articular fossa.

The top of the hole and continue to interact, though not quite right. In this situation, the head of the joint does not go beyond the cartilage plate. When correct methods of struggle with dysplasia joint has a chance to return to a normal position in the opposite situation, there is a significant probability of the transition of this state to complete dislocation.

Dislocations can be characterized by complete displacement of the femoral head, and they are considered the most severe types of dysplasia of the articular parts of bones.

When dislocation occurs the dysfunction of the interaction of the articular fragments with damage to the joint capsule and without or after mechanical damage or under the influence of disease processes in the articular cavity.

Typology of subluxations

Dislocations of the hip joint are divided into complete and incomplete. Sprained considered the most distant from the body portion of the limb. Dislocation is inherited is considered the most severe degree of this pathology, and it can be characterized by a complete change of the dislocation of the top of the thigh.

The main factor of disease - genetic predisposition, pathology of the mother duringpregnancy or prior symptoms of instability of the articular planes and hollows. The newly acquired subluxation occurs due to improper babies, as well as his long stay in the crib with locking hip joint for a long time.

The signs of the disease

Signs of subluxation of the hip joint most often are determined before birth into the light.

The longitudinal position of fetus, permanent toxicity during pregnancy, such disorders of the hip in one of the parents or next of kin, the modification of the feet or the excessively large size of the fetus are usually the symptoms that the child after birth there would be some form of dysplasia.

There are 4 types of orthopedic features of the subluxation of the joints:

  • shortening of the hip joint;
  • the defect in the skin folds;
  • syndrome slipping Brand-Ortolana and in the interpretation of Barlow;
  • the inability or difficulty in abduction of the thigh.

Symptoms diagnosis when physical examination is necessarily carried out by the specialist of the corresponding profile. By visual inspection pay attention to such characteristic as the line of the skin crease to the diligence of the limbs in a resting state. The asymmetry is most informative in the first weeks after birth. Sciatic, groin and knee creases deeper and more quantitatively.

The phenomenon of shortening of the hip joint

The phenomenon of shortening of the thigh is an important factor in identifying this disease, which can be characterized by reduction of total bone joint due to a back shift of the femoral head in the area of the acetabular fossa.


He points to the legacy of subluxation of the hip and is confirmed by the fact that the child lying on her back in the position with bent knees and hip joints, one knee is lower than the other. The reasons for this anomaly lie in abnormal development of the hip joint.

To timely recognize and diagnose the disease owes specialist-orthopedic surgeon during the initial examination of a newborn baby still in the hospital. Then these children (consisting on the account at the orthopedist with a high risk of developing dysplasia in the future) or children with already diagnosed subluxation of working with the podiatrist inthe local district hospital. Them there is prescribed a special orthotic treatment that do not cancel before the final diagnosis is rendered.


The final diagnosis is inferred on the basis of visual examination, the results of technical ways of identifying pathology and long-term monitoring of the child's behavior. To delay treatment to the doctor and treatment is impossible because of subluxation of the hip in adolescents and adults is almost incurable due to the persistence of the anomalous position of the plane of the joint relative to each other, developed with age.
