    Abstract: A vertebral body is selected for treatment. The vertebral body has a cortical wall enclosing a cancellous bone volume. The vertebral body has at least one cortical plate that is depressed due to fracture. At least one maximum dimension for the cancellous bone volume is ascertained. An expandable device is provided having an expanded configuration and an unexpanded configuration. The expandable device has a predefined dimension when substantially expanded that is less than the maximum dimension. The expandable device is introduced into the vertebral body through a percutaneous access path while in the unexpanded condition. The expandable device is expanded while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration to create a cavity that occupies less than the cancellous bone volume.
