HIP SURGERY

Hip prosthesis for dysplasia

Hip dysplasia is the result of an abnormality in the development of the joint during growth. This developmental abnormality begins during foetal growth and continues into early childhood.

The different degrees of dysplasia

There are several degrees of severity. Simple dysplasia is characterised by insufficient hollowing of the acetabulum, i.e. the part of the hip joint in the pelvis. This dysplasia of the acetabulum is of varying degrees of severity. It results in poor distribution of the forces applied to the head of the femur when walking, performing everyday activities or playing sports. This excess pressure on a small area of the head leads to premature wear and tear and osteoarthritis of the hip.

This osteoarthritis caused by dysplasia is responsible for joint pain and functional limitations over the years. When it becomes disabling, a hip prosthesis is an effective and lasting solution.

In the most severe forms, we do not speak of hip dysplasia but of congenital dislocation. This form is characterised by the femoral head rising upwards and no longer being in contact with the acetabulum of the pelvis. The dislocation is often associated with significant shortening of the leg. 

When should a hip replacement for dysplasia be considered?

Surgery is indicated in the presence of :

  • osteoarthritis secondary to dysplasia confirmed on X-rays and sometimes a CT scan 
  • chronic pain that becomes incapacitating
  • often with more or less pronounced lameness
  • increasing difficulty walking and carrying out everyday activities

Specific features of hip dysplasia surgery

In minor forms of dysplasia, the post-operative course is the same as for the insertion of a total hip prosthesis on classic osteoarthritis without dysplasia. Walking is resumed immediately after the operation.

The operation is performed anteriorly. The canes can be removed after two to three weeks.

Rehabilitation sessions may be prescribed at a later stage (not during the first five to six weeks).

On the other hand, in severe cases requiring reconstruction of the joint, or in cases of true congenital dislocation, it is often necessary to allow a period of a few weeks with partial support for the operated leg. The canes are then kept on for five to six weeks. Convalescence takes a little longer. The resumption of physical activities is also delayed.

Bilateral hip osteoarthritis on dysplasia

Bilateral hip osteoarthritis due to congenital dysplasia. The left hip was operated on (custom-made prosthesis).

What results can we expect?

The aim of hip replacement for dysplasia is to eliminate pain and restore better joint function. 

It enables patients to regain comfort in their daily lives.

Frequently asked questions (FAQ)

Is hip replacement for dysplasia different from a conventional prosthesis?


In some cases, we recommend using an operating technique that is better adapted to the anatomical features of the dysplastic hip.

What is the recovery time?


Walking is usually resumed immediately. Resumption of full weight-bearing may sometimes be delayed by a few weeks if bone reconstruction has been necessary.
