1. An apparatus for use in spinal interbody fusion, comprising:
an expandable device including a first outer surface for contacting one vertebral body in a spine and a second outer surface for contacting a second opposing vertebral body in said spine, a front end, a rear end, and a channel extending into said expandable device;
an inserter including a track assembly having a distal end and a proximal end, said inserter being releasably attached to said expandable device;
an insert supported by said track assembly for insertion into said expandable device through said channel, said insert including an angled lifting surface configured and oriented to cause expansion of said expandable device during insertion of said insert; and
a guide pin releasably connected to said expandable device and detachably connected to said track assembly, said guide pin being supported by said track assembly and being detachable therefrom, said guide pin remaining releasably connected to said expandable device upon detachment of said inserter from said expandable device and said guide pin, said guide pin being configured to serve as a locator for subsequent attachment to another apparatus, including an apparatus for introducing bone graft material into said expandable device through said channel.
