摘要:
An intervertebral implant comprises a first component and a second component. The second component includes an actuator and a third component comprises a first ramp and a second ramp axially spaced apart from the first ramp. The third component comprises rails including at least a portion of the ramps. At least one of the ramp portions disposed with the first rail has a first height and at least one of the ramp portions disposed with the second rail has a second height. The first height is greater than the second height. The actuator is engageable with the third component to effect axial translation such that the ramps engage at least one of the components between a first configuration and a second configuration. Methods of use are disclosed.
