Abstract
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.
Claims11
An antibiotic delivery system comprising:
- a femoral intramedullary stem adapted to be removably mounted in the medullary canal of a femur bone following the removal of an infected hip prosthesis;
- said stent including an inlet adapted to be in fluid communication with a source of fluid-borne antibiotic, a plurality of outlets disposed along said stem and a channel extending between said inlet and said plurality of outlets for delivering fluid-borne antibiotic from said inlet to said plurality of outlets so as to distribute said antibiotic along the medullary canal in a controlled fashion.
An antibiotic delivery system comprising:
- a femoral intramedullary stem adapted to be removably mounted into a medullary canal of a femur bone, said femoral intramedullary stem including a body having a proximate end and a distal end disposed remote from said proximate end, a femoral head and a neck extending from said proximal end of said body and between said body and said femoral head, said femoral intramedullary stem including at least one inlet, said body and said femoral head having a plurality of outlets and a channel extending between said at least one inlet and said plurality of outlets for delivering fluid-borne antibiotics from said at least one inlet to said plurality of outlets so as to distribute said antibiotic along said intramedullary canal and the socket of a hip joint in a controlled fashion.
A method of treating an infected joint during a two-stage re-implantation of an orthopedic implant, said method comprising the steps of:
- removing the infected implants mounted to the medullary canal of a bone;
- debriding the medullary canal;
- installing an intramedullary stem into the medullary canal where the stem includes an inlet, a plurality of outlets and a channel extending between the inlet and the plurality of outlets;
- providing a source of fluid-borne antibiotic to the inlet of the intramedullary stem so as to distribute the antibiotic into the medullary canal in a controlled fashion.
