1. An apparatus for separating a femoral head that has been inserted into a mobile insert adapted to be received in an acetabular shell, the apparatus comprising:
an impactor having an impaction tip sized to be inserted into a central impactor opening at a bottom of the mobile insert to push against the inserted femoral head;
a removal base having a circumferential wall defining an upper surface adapted to receive an upper portion of the mobile insert having the inserted femoral head, the circumferential wall defining a central removal opening having a larger diameter than an exterior diameter of the femoral head, but smaller than an exterior diameter of the mobile insert, the central removal opening further including a tapered region below to catch the femoral head when the femoral head separates from the mobile insert as a result of an impaction to the femoral head with the impaction tip.
