1. A fluid delivery system for disinfecting a joint after removal of a prosthesis from said joint, said system comprising:
a femoral head configured to be disposed in an acetabulum, the femoral head comprising:
a partially spherical, outer shell forming an external surface of the femoral head, the outer shell comprising a plurality of outlets and a first radius of curvature;
a partially spherical, inner shell located internal to the outer shell, the inner shell comprising a second radius of curvature smaller than the first radius of curvature;
a central shaft projecting through the interior of the femoral head, the central shaft coupled to a region of the inner shell and defining a central channel;
an outer cavity disposed near a periphery of the femoral head, the outer cavity bound by an inner surface of the outer shell and an outer surface of the inner shell, wherein the outer cavity is in fluid communication with the central channel and the plurality of outlets; and
an inner cavity located inside the femoral head internal to the outer cavity, wherein the inner cavity is defined, in part, by an inner surface of the inner shell, wherein the inner cavity is not in fluid communication with any of the central channel, the outer cavity, or the plurality of outlets;
a femoral stem coupled to the femoral head so as to be in fluid communication with the central channel, the femoral stem configured to be disposed in a femoral medullary canal, wherein the femoral stem comprises a threaded neck region, the threaded neck region configured to be threadably engaged with the femoral head thereby allowing adjustment of a distance between the femoral head and the femoral stem; and
an inlet coupled to the femoral stem,
wherein, when the system receives a fluid from the inlet, the fluid is deliverable from the plurality of outlets into the acetabulum.
