An antibiotic delivery system including an intramedullary stem that is adapted to be removably mounted into a medullary canal of a bone. The stem includes a body having an inlet adapted to be in fluid communication with a source of liquid-borne antibiotic and a plurality of outlets disposed along the stem. A channel extends between the inlet and the plurality of outlets for delivering a fluid-borne antibiotic from the inlet to the plurality of outlets so as to distribute the antibiotic along the medullary canal in a controlled fashion. A method of treating an infected joint during a two-stage re-implantation of an orthopedic implant is also disclosed.

An orthopedic system for delivery of a therapeutic agent to a bone includes an elongate stem adapted to be inserted into an intramedullary canal, an inlet configured to receive the therapeutic agent, and one or more outlets configured to deliver the therapeutic agent to the bone. The elongate stem may comprise one or more protrusions to engage the bone, and one or more channels extending longitudinally therein, fluidly coupled to the inlet. The therapeutic agent flows from the inlet through the one or more channels and exits into the intramedullary canal through the one or more outlets. The system may be configured to allow one or more dimensions of the system to be adjusted to accommodate the anatomy of a patient.

A method of assembling a mobile bearing acetabular component of a prosthetic hip joint is disclosed. The method includes mounting an acetabular cup insert to an acetabular cup. The method includes concurrently repositioning the acetabular cup insert deeper into an interior of the acetabular cup and repositioning the acetabular cup insert outside of an outline of the acetabular cup.

A joint implant component (1, 1; 101; 201) for administering a pharmaceutical product is disclosed, which comprises an implant shaft (10, 10; 110; 210), a joint section (20, 20; 120; 220) arranged at the proximal end of the implant shaft, a flush supply opening (3, 3; 103; 203) and a backflush opening (4, 4; 104; 204). At least one shaft flush channel (11, 11; 111; 211) and one shaft backflush channel (12, 12; 112; 212) extend along the implant shaft inside the implant shaft. The shaft flush channel is connected to the outside of the implant shaft via shaft flush holes (13, 13; 112; 113) for discharging the pharmaceutical product, and the shaft backflush channel is connected to the outside of the implant shaft via at least one shaft backflush hole (14, 14; 114; 214) for receiving the discharged pharmaceutical product. The flush supply opening is fluidically connected to the proximal end of the shaft flush channel and the backflush opening is fluidically connected to the proximal end of the shaft backflush channel. Also disclosed is a joint implant comprising two such joint implant components which are connected to one another by means of joint surface parts (30, 40; 230) and are pivotable relative to one another.
