In one embodiment, an apparatus includes an elongate body and an expandable member coupled to the elongate body. The expandable member is configured to be disposed within an interior of a vertebral body having a first portion that includes cancellous bone and having a second portion that includes sclerotic bone distinct from an endplate of the vertebral body. The expandable member is configured to exert a first pressure on the first portion of the vertebral body and a second pressure different from the first pressure on the second portion of the vertebral body. The second pressure is sufficient to move the second portion of the vertebral body in a direction away from the expandable member when the expandable member is expanded within the interior of the vertebral body.
