Disclosed herein are devices (100), systems and methods of use relating to articulating interbody cages. In one aspect, disclosed is an intervertebral device (100) for use in a human spine including an anterior end (104); a posterior end (102); and at least four peripheral walls (22,24,26). The peripheral walls (26) define an interior volume surrounding a midline of the device and include a superior wall (22), an inferior wall (24) and a pair of opposing, generally trapezoidal-shaped sidewalls. Each of the trapezoidal-shaped sidewalls (26) includes an internal hinge element (60) that is rotatable from a first configuration to at least a second configuration such that the device is expandable in first dimension. Each of the internal hinge elements includes an axis that is coplanar with the midline of the device.
