Can my hip be corroding?
Hips can only corrode if there are two different metals attached to each other. Even then, corrosion is unlikely, but it can happen, and is particularly likely if the stem is one metal, the femoral head another, and the acetabular shell still another. In these hips, the so called Large Diameter Metal-on-Metal Total Hip Arthroplasties (LDMoMTHA), corrosion has been a problem. The process has occurred at the junction between the stem and the femoral head. This process has produced many more wear particles and an entirely new problem. It is this problem that has caused all the fuss. The companies that supplied the heads and stems and sockets did not appreciate what a problem it would cause.
