BONE-TREATMENT INSTRUMENT AND METHOD

摘要

Photodynamic therapy (PDT) is used to treat bone. A photosensitizing drug is administered to a mammal. Non-thermal light at a specific wavelength is delivered to a site adjacent or in bone to activate t he drug. A cannulated bone screw is secured into bone. A fiber optic cable sheath extends from within the screw and is accessible. A fiber optic cable is inserted in the fiber optic cable sheath to deliver light to the bone. The light activates the drug. The cannulated bone screw and the fiber optic cable sheath may remain inside the mammal for further photodynamic therapy.
