Coxa Valga: causes, symptoms, diagnostics, treatment

Dysplastic coxarthrosis, or Coxa Valga, is a disease that is characterized by degenerative changes in the hip joints. The disease is a consequence of a congenital joint pathology, dysplasia.

In case of dysplasia, the joint is underdeveloped, the acetabulum is formed incorrectly and caput-collum-diaphyseal angle is broken. If this angle is above the norm, then the diagnosis of Coxa Valga, that is, valgus deformity of the femoral neck can be stated. Such a pathology is practically not subject to conservative treatment, but it can be eliminated at Ladisten Clinic using high-tech osteotomy.

Сoxa Valga – what is it?

In each newborn, femoral neck is in the valgus position – it means that it is turned back. In the process of growth, a physiological reversal occurs, and the femoral head occupies its correct position. This can be tracked by the values ​​of caput-collum-diaphyseal angle which should be 127-130 degrees in average.

But under the influence of certain factors, the cartilages undergo certain changes, and the process of reversal is disrupted.

When the angle exceeds 139 degrees, Coxa Valga appears. Over time, the pathology leads to severe changes in bone structures and surrounding tissues so they are destroyed and the cartilage is worn away. The joint, which was already unhealthy, is deformed more and coxarthrosis develops. Arthrosis of the hip joint is one of the most severe pathologies with dangerous consequences.

Causes of the illness Coxa Valga

Coxa Valga can develop immediately after birth or years later. There are several factors for it to occur:

• Little’s disease;
• consequences of poliomyelitis;
• progressive muscular dystrophy;
• tumors in the area of ​​the epiphyseal cartilage.

Less commonly, pathology occurs after rickets or improper treatment of an injury.

And the most common cause of the disease is hip dysplasia. This is a condition in which the head of the joint is underdeveloped or the acetabulum is flat, not formed properly.

The most severe form is congenital hip luxation. But other degrees of dysplasia are no less dangerous. If left untreated, they trigger coxarthrosis. As dysplasia progresses, cartilages in the acetabulum and on the femoral head degenerate. In more than 70% of cases, it is the acetabulum that suffers.
