Joint preserving surgical care of hip disorders

The hip joint has amongst other things a two-fold function: The joint must transmit a significant load from the body to the lower limbs and allow significant mobility within the three planes of space.

Optimal load transmission and stability occurs through maximal coverage of the head of the femur by the acetabular cup. Optimal mobility of the joint occurs through a minimum of constraints or minimal coverage of the head of the femur.

We believe that a majority of articular dysfunction and pain about the hip joint results from a dysbalance or mismatch between morphological inheritance and function.

There are some surgical means which may safely correct such unfavorable conditions. These belong in the realm of so-called joint preserving surgery of the hip joint.

Open revision of the hip joint

There might be cases which demonstrate a morphological discrepancy or mismatch between the cup of the acetabulum, the head and the neck of the femur.

This mismatch might be congential (inherent) or acquired. The discrepancies may lead to early degeneration and pain. By means of an open surgical approach to the hip joint (surgical dislocation of the joint), the joint surfaces can be seen, and possible coxo-femoral impingement (mismatch between the joint surfaces within normal range of movement) can be evalutated.

Bony and soft tissue impingement are dealt with and adaptations made to optimize hip joint function (cheilectomy of the femoral head, re-shaping of the acetabular cup). This operation can be done without harming the soft tissues or jeopardizing the femur.

It is much less invasive than, for example, joint replacement of the hip and may avoid or at least significantly delay the need for more invasive surgical means.
