Abstract
Apparatus for positioning a prosthetic acetabular cup within an acetabulum during total hip replacement surgery. The apparatus includes a pusher ball, a pusher arm affixed to the pusher ball, a positioner arm, and a positioner flange affixed to the positioner arm. The apparatus also includes a slot within the flange dimensioned to receive a part of the pusher arm so that the flange can be faced with the pusher ball. The apparatus can affix the flange facing the ball to define a predetermined angle between the pusher arm and the positioner arm. This apparatus also releasably secures the ball generally mated with the acetabular cup, so that the positioner flange and the positioner arm can be released and removed from the remainder of the apparatus while the pusher ball remains within the acetabular cup to maintain uninterrupted pressure on the acetabular cup via the pusher arm.
