摘要：
Methods of creating a curvilinear cavity within a vertebral body or other bony structure and devices that may be used to perform the steps to create the curvilinear cavity. In one embodiment, a method of forming a curvilinear void in bony structure may include the steps of accessing a bony structure with a cannula, inserting a distal end of a drill device through the cannula and into the bony structure, manipulating the distal end of the drill device to create a curvilinear void in the bony structure, enlarging the void by expansion of a balloon element mounted to the drill device, and deflating the balloon element and removing the drill device from the cannula.
