ABSTRACT:
An acetabular cup shell inserter has a first end with a handle and a wire coupling element. The inserter has a shell insertion end opposite the first end having a radial expandable element for contacting an inner surface of the acetabular cup shell. A tubular portion is provided extending between the handle end and the insertion end. The tubular portion may be curved. A wire having a first end coupled to the coupling element at the first end is provided. The wire extends through the tubular portion and into the insertion end, the wire having a second end coupled to a moveable element for expanding the expandable element. The inserter includes a system for applying tension to the wire, such as by moving the wire in a direction towards the first end, the tension causing the expandable element to expand and grip the inner surface of the shell.
