The Austin Moore Prostheis shown was introduced in 1952 by Dr Austin Moore of the Johns Hopkins Hospital, Baltimore USA as a treatment for a fracture of the neck of the femur since this injury compromises or deprives the ball shaped head of femur of blood supply. It is still in use. The replacement head fits into the existing cup-shaped recess (acetabulum) in the pelvis. It is not suitable for treatmet of arthritis of the hip as half orf the painful arthritic joint is retained. The device replaced a previous design that was shaped to be applied and screwed to the outside of the truncated femoral shaft. The prosthesis comes in a ranges of sizes, of which one is chosen to best fit the receiving acetabulum. It was originally manufactured in 'Vitallium'® - an alloy of 60% cobalt, 20% chromium, 5% molybdenum, and other substances - chosen for its light weight and resistance to corrosion.
