Abstract: An intervertebral implant may include an input for expanding at least two extendable support elements connected to a body at respective locations, such that the extendable support elements each apply a respective expansion force directed away from a surface of the body. Application of a single input force to the input may induce the extendable support elements to apply different amounts of expansion force. Alternatively or additionally, an intervertebral implant may include at least two portions connected together by a hinge for articulation about the hinge. In one aspect, the hinge may include at least two rigid links each pivotably connected to the two portions. In another aspect, a rigid link of the hinge may include a passageway for communicating a hydraulic fluid between the two portions. A locking system may be positionable into successive locked configurations by operation of a cam to prevent contraction of an extendable support element.
