1. A method comprising:
- selecting a vertebral body for treatment, the vertebral body having a cortical wall enclosing a cancellous bone volume, the vertebral body having at least one cortical plate that is depressed due to fracture,ascertaining a maximum anterior-to-posterior dimension for the vertebral body measured between anterior and posterior cortical walls,providing an expandable device including an expanded configuration and an unexpanded configuration, the expandable device having a predefined dimension when substantially expanded that is less than the maximum anterior-to-posterior dimension,introducing the expandable device into the vertebral body through a percutaneous access path while in the unexpanded condition, andexpanding the expandable device while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration to move the fractured cortical plate toward a desired anatomic position.

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 move the fractured cortical plate toward a desired anatomic position.

9. A method comprising
selecting a vertebral body for treatment, the vertebral body having a cortical wall enclosing a cancellous bone volume, the vertebral body having at least one cortical plate that is depressed due to fracture, ascertaining a maximum lateral dimension for the vertebral body measured between lateral cortical walls, providing an expandable device including an expanded configuration and an unexpanded configuration, the expandable device having a predefined dimension when substantially expanded that is less than the maximum lateral dimension, introducing the expandable device into the vertebral body through a percutaneous access path while in the unexpanded condition, and expanding the expandable device while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration to move the fractured cortical plate toward a desired anatomic position.
