An implant system (16, 18, 20 and 22) for fusing vertebrae includes a variety of shapes that may be stacked to accommodate different intervertebral spacings and curvatures. The implants (16, 18, 20 and 22) comprise polymer-bone composites that have osteogenic properties. By selection of an appropriate set of shapes, the surgeon can tailor the overall shape of the implant before or during surgery, in order to best match the shape of the intervertebral cavity for a particular patient. |
