Abstract
A method for controlled delivery of fluids to the exterior of bone and surrounding tissue of a patient includes providing a cannulated bone rod. The method further includes creating an aperture in the skin of a patient and fixating the rod along bones or bone fragments using a spinal fixation system through the aperture. A spinal fixation system includes a bone screw having a longitudinal access and a bone rod configured to connect the bone screw to at least one additional bone screw. The bone rod is lateral to the longitudinal axis. The method further includes the steps of providing a fluid source, coupling the fluid source to the bone rod, and delivering a fluid from the fluid source into the bone rod. An additional method includes using the fixation system as a point of drainage for the posterolateral fusion site.
