Abstract
An antibiotic eluding intramedullary nail apparatus for use in the intramedullary fixation of fractured long bones, such as femurs, tibias, fibulas, humeri, ulnas and radii, as well as other orthopedic and bone reconstructive procedures, and, in particular fractures associated with an open wound exposing the soft tissue and medullary canal of the fractured bone to bacteria and other infectious micro-organisms. The apparatus includes an intramedullary nail to which is secured an antibiotic impregnated carrier compound, the apparatus being surgically insertable within the medullary canal of a fractured bone using conventional intramedullary nailing techniques thus providing a sustained localized release of antibiotic agents in bactericidial concentrations, and/or chemotherapeutic agents for bone tumors, directly within the medullary canal of the fractured bone and thereby serving to permit the use of intramedullary nailing to repair injuries which may be otherwise contraindicated due to the risk of deep wound and/or bone infections and/or bone tumors.
