Abstract:
1. An implant unit for repairing a vertebral segment or segments or a bone repair site in mammalian bone comprising: an implant portion for insertion into an intervertebral space or bone repair site extending in an insertion plane and juxtaposed with surfaces to be repaired, the implant portion having a top surface and a bottom surface, wherein the top surface and bottom surface of the implant portion are contoured to complement the surfaces to be repaired; and a retaining portion for retaining the implant portion in the intervertebral space or bone repair site, the retaining portion being formed of an osteogenic material and extending in its longest dimension transversely to the insertion plane of the implant portion, being provided on a proximal end of the implant portion, and being attachable to a sidewall of the at least one vertebral body or a mammalian bone, the retaining and implant portions being configured and coupled to one another so that during the period of repair the retaining portion substantially prevents displacement of the implant unit relative to the surface to be repaired and the implant unit carries loads over the intervertebral space or the mammalian bone, wherein the implant portion has a flange extending laterally outwards from at least one end of the implant portion, the flange being received in a stepped central opening of the retaining portion and being dimensioned so that the flange extends flush with an outer surface of the retaining portion after the implant unit is inserted into the intervertebral space or bone repair site.
