Abstract
An apparatus includes a scaffold configured to be disposed in a bone. The scaffold is configured to move from a first configuration to a second configuration. The scaffold in the second configuration is expanded from the first configuration. A selectively-expandable actuator is configured to be removably disposed within the scaffold. The selectively-expandable actuator is configured to move at least a portion of the scaffold to the second configuration when the selectively-expandable actuator is moved to an expanded configuration. A shape of the selectively-expandable actuator is substantially the same as a shape of the scaffold when the selectively-expandable actuator and the scaffold are in the second configuration. The selectively-expandable actuator configured to be removed from the scaffold when in a collapsed configuration. The scaffold is configured to remain substantially in the second configuration after the scaffold has been expanded by the actuator.
