STRUCTURALLY SUPPORTING INSERT FOR SPINAL FUSION CAGE

摘要

An expandable implant includes a structural insert to provide a robust connection between an insertion instrument and the expandable implant. The structural insert can be made from a different material than the remainder of the implant to withstand compressive, tensile, shear, and torsional loads which may be present while inserting the implant into a patient. The structural insert may be formed as part of a bottom member of the implant or may be a separate element inserted into the implant body. The structural insert may provide a threaded connection to an insertion instrument. The expandable implant may include a bone graft port in fluid communication with a bone graft opening extending through the implant body.
