Abstract
A spinal implant includes a first component including a first surface configured for engagement with a first vertebral surface and a second surface configured to define at least a portion of an implant support cavity. A second component is connected to the first component and includes a first surface configured for engagement with a second vertebral surface and a second surface configured to define at least a portion of the implant support cavity. A removable intermediate component is configured for disposal in the implant support cavity. The intermediate component is inflatable to move the first component relative to the second component to expand the interbody implant from a first configuration to a second, expanded configuration. At least one agent is configured to replace the intermediate component in the implant support cavity in the second configuration. Methods of use are disclosed.
