Abstract
An instrument for implanting an acetabular cup prosthesis in a patient's acetabulum. The cup is gripped on the base of the instrument and is aligned and inserted in accordance with a plane normal to the plane in which a patient is positioned and normal to a line between the right and left anterior/superior iliac spines. With the acetabular cup so aligned, the cup is impacted to be retained in a prepared acetabulum. The instrument is actuated for gripping the cup for the aforenoted alignment, insertion and impaction and is thereafter actuated for releasing the cup so that the instrument can be removed from the cup without disturbing the position thereof.
