A device having an adjustable height and angle to space vertebral members. The device includes a plurality of links that extend between a plate and a deployer. A first section of the deployer is moved to change the angle of the plurality of links and expand the height of the spacer. A second section of the deployer is moved to change the angle of the plate relative to the centerline. A method of using the spacer is also disclosed and includes positioning the spacer while in the closed orientation between the vertebral members. The spacer is then expanded to a second height. The angle of the spacer is than adjusted as necessary to space the vertebral members.
