Abstract:
1. A fusion implant adapted to fuse bone within a skeletal system, comprising: a body sized and shaped for implanting between bones of a skeletal system, the body defining an internal cavity configured to contain implanted bone graft or bone graft substitute, wherein the body includes a first skeletal bone abutment surface and a second skeletal bone abutment surface both surfaces being adapted to abut adjacent skeletal bones, wherein the abutment surfaces are connected by at least one wall and wherein, when implanted. in the skeletal system, the skeletal bone abutment surfaces support a structural load transmitted through the skeletal bones when implanted in the skeletal system; a load member that forms at least a portion of the boundary of the internal cavity, wherein the load member that is separate from the wall of the body and does not form a portion of the abutment surface, and wherein the load member is spring biased to move towards the internal cavity and provide a compressive load upon the contained bone graft material.
