Abstract
Systems and method create a cavity in cancellous bone by use of a system or kit that includes a cannula having an axis that establishes a percutaneous path leading into bone and a shaft having a distal end portion carrying an elongated loop structure or bristles capable of extension from the shaft to create a cavity forming structure. The shaft is movable relative to the axis of the cannula to move the cavity forming structure when extended within cancellous bone to form a cavity in the cancellous bone. A tool is sized for passage through the cannula. The tool is capable of dispensing a filling material into the cavity.
