Abstract:
1. A surgical method, comprising: forming a cavity in bone, the cavity having a first maximum diameter; forming a first access tunnel providing access into the cavity, the first access tunnel having a second maximum diameter that is less than the first maximum diameter; advancing a graft into the cavity through the first access tunnel such that a first portion of the graft is positioned within the cavity, and a second portion of the graft extends out of the cavity; and inserting a hardenable filler material in a first state into the cavity, the hardenable filler material causing the first portion of the graft to expand and push against walls of the cavity such that when the hardenable filler material changes from the first state to a second, harder state, the first portion of the graft is prevented from exiting the cavity through the first access tunnel.
