Abstract
An augment for an orthopaedic implant contains a countersunk through hole. A fixation means interacts with the countersink to produce both downward and lateral forces on the augment. As the fixation means is tightened, it abuts one side of the countersink so that it exerts both a downward force and a lateral force on the augment. The lateral force causes the augment to press tightly against the implant. Because of the combination of downward and lateral forces, the augment strongly resists displacement and rotation.
