What happens if congenital hip dysplasia is not corrected?

If congenital hip dysplasia is not corrected, the hip joint will be unstable and in some cases, dislocation may occur.

As the femoral head and acetabulum move without proper alignment, the cartilage in the joint will wear down unevenly and prematurely. It can result in differing degrees of osteoarthritis, depending on the degree of misalignment.

Hip dysplasia can also include an atypically shaped thighbone.

Ideally, the ball and shaft of the femur for a 120- to 135-degree angle where they meet. In hip dysplasia, however, the angle can change in one of two ways. In coxa valga, the angle between the ball and shft is increased, usually higher than 135 degrees. In coxa vara, however, the angle is reduced to lower than 120 degrees.

In either case, femur length is affected. Coxa vera shortens the femur and coxa valga lengthens it. Either situation creates imbalance and results in difficulty in pain, walking and joint stiffness.
