A system for replacing a portion of a hip joint can include a cup having an outer surface and an inner surface. A bearing can include an outer bearing surface and an inner articulating surface. The outer bearing surface can be positioned adjacent to the cup. A ring can be selectively disposed between the cup and the bearing. The ring can define an annular body having a slit formed therein. A removal tool can define a proximal end and a distal end. The distal end can define a ring engaging surface and a bearing engaging surface. The ring engaging surface can be adapted to engage the ring at the slit such that the ring expands radially from a locked position away from engagement with the bearing to an unlocked position. The bearing engaging surface can be adapted to engage the bearing and urge the bearing away from the cup.
