Abstract
A cup impactor assembly comprises a shaft. A cup coupler is at a cup end of the shaft and is releasably connecting a cup in fixed relation. A handle is at an impacting end of the shaft. A visual guide is mounted to at least one of the shaft and the handle, the visual guide producing visual guidance for pointing at at least two landmarks of the pelvis or fixed relative to the pelvis, based on a pre-planned patient-specific relation between the at least two landmarks and a desired acetabular cup orientation relative to the landmarks. A method for orienting an acetabular cup prior to impacting in an acetabulum of a pelvis is also provided.
