Abstract
In one aspect, a system and method for aligning hip replacement prostheses comprises an acetabular liner having an inner concave surface and an outer convex surface. The acetabular liner includes at least two magnetic sensors arranged in a spatially distributed manner. The system and method also include a prosthetic femoral component comprising a femoral head component. The femoral head component and the acetabular liner component are shaped such that a ball and socket joint is formed when the femoral head component comes into contact with the inner concave surface of the acetabular liner. While the ball-and-socket joint is formed, and in at least some orientations of the femoral head component relative to the acetabular liner component, a contact point on an external surface of the femoral head component contacts the inner concave surface. The femoral head component includes at least one permanent magnet.
