Abstract
The acetabular cup positioner of this invention provides a resilient collar to be carried on its distal end for contacting the interior surface of the acetabular cup. The resilient collar prevents damage to the interior of the cup during impaction. Since the resilient collar will compress a small amount during the impaction, the threaded connector of the positioner and the threads for the acetabular cup will be under a sizable load. Therefore, to protect the positioner and the cup, the threaded connector is shiftably connected to the positioner body. The connector is biased toward the distal end by a helical spring.
