Abstract
Abstract Systems and methods for delivering material into bone deploy a cannula through soft tissue to establish a subcutaneous path into bone. A material is introduced into bone through the cannula. The systems and methods advance a tamping instrument through the cannula to urge material residing in the cannula into bone. The introducing step delivers material at a pressure no greater than about 360 psi.
