摘要：
A cage for facilitating fusion of bones, such as vertebrae, or fusion of adjacent bone surfaces is disclosed. In one form, the cage includes a plurality of spaced apart walls comprising a biodegradable polymeric material (e.g., polycaprolactone)； an osteoconductive mineral coating (e.g., a calcium compound) on at least a portion of the walls； and a bioactive agent (e.g., a bone morphogenetic protein) associated with the polymeric material and/or the coating. The bioactive agent is present in amount that induces ossification between the bones or adjacent bone surfaces. The cage may also include a fixation plate connected to at least one of the walls.
