Abstract
A spinal fusion system method and apparatus can include: providing segments including a first segment and a second segment; and coupling the first segment to the second segment with a flexible member, the flexible member configured to have a deformable state based upon a temperature of the flexible member being below a transition temperature range or based upon a stress being applied to the flexible member, and the flexible member configured to enter a shape-set state from the deformable state based on the temperature of the flexible member rising above the transition temperature range, or based upon the stress being removed from the flexible member and the temperature of the flexible member being above the transition temperature range.
