The objectives of the replacement of total hip prosthesis are several:
For this purpose we use revision implants depending on the degree of wear, both at the acetabulum and at the level of the femur. In the same way allograft or bone transplant is used according to each case and according to a predetermined classification. For example, in the acetabulum we use the modified Icatme classification of Gross with four grades, which is illustrated in the drawing on the right.
The most common cases correspond to grades I and II. We usually use tantalum cups (80% more porous reticulated titanium) and in some cases graft-transplant fragmented-impacted filling according to the Sloof technique. In grades III and IV where there is a lack of a spine, usually the posterior, or a floating hip remains, we use the massive acetabulum transplant from the bone bank. Together with Mount Sinai Hospitals in Toronto and Rush Presbiterian Hospital in Chicago we have the largest experience in this type of transplants in the world.
