1. An expansion member for distributing graft material through an expandable cage and into an intervertebral space between a top vertebral plate and a bottom vertebral plate, the expansion member comprising:
a central beam with a central beam axis, the central beam having a graft distribution channel with an entry port in fluid communication with an exit port;
wherein the central beam is configured for insertion into the expandable cage to form a graft distribution system within the intervertebral space; and
wherein the central beam is configured to expand the expandable cage during insertion of the central beam into the expandable cage.
