This surgery is indicated for recurrent hip luxation, severe unrepairable fracture of the hip (acetabulum or femoral head) or severe osteoarthritis.

 

The aim of the surgery is to eliminate pain caused by bone on bone contact between the hip bones (femoral head and acetabulum).

 

Following the removal of the femoral head and neck with an oscillating electric saw, the mechanic of the joint during the movement will rely on tendon and muscles rather than the bony support.

 

Ideally, the hip joint should be replaced with a prosthesis (hip replacement) to restore normal anatomy. However, when a total hip replacement cannot be performed, a good motion of the limb is also achieved without the bony support, especially for patients weighing less than 20 kg. Even though the functionality of the leg can vary case by case, this is never associated with pain.

 

Pain management and accurate surgery allow early movements of the limb and fast-developing of a good muscle tone, which is fundamental for joint stability. A rehabilitation programme and hydrotherapy should be started once the patient is weight-bearing to encourage limb movements.

 

The rate of complication is very low.
