The safety of hip replacement systems is influenced by, for example, the materials of the ball and stem or taper, the method of joining, heir shape, and the state of their surfaces. These factors, and specifiations for manufacturers and in the operating theater, are briefly reviewed. The metal taper shown in the Figure has a typical defect —it does not meet the straightness requirement—which could lead to failure.
