An acetabular cup extraction system includes a sealing member which is securable to an implanted acetabular cup. A elongate member is engagable with the sealing member to facilitate removal of the cup from the patient's acetabulum. In one embodiment, the sealing member includes a passage for coupling with a vacuum source to evacuate an interior portion of the cup and thereby enhance the engagement of the sealing member to the acetabular cup.
