Abstract
An expandable spinal implant including a first member and a second member. The first member has first and second arms. The first and second arms of the first member both including an upper face partially defining an upper contact area of the implant and a lower face partially defining a lower contact surface of the implant. The second member has first and second arms that both include an upper face partially defining an upper contact area of the implant and a lower face partially defining a lower contact surface of the implant. The first and second members are pivotally coupled to each other for relative movement about a rotation axis between a closed position for inserting the implant into a spine and an expanded position for providing structural support to the spine. The rotation axis extends generally perpendicular to the upper and lower contact surfaces.
