<p>Implantable devices (10) useful for creating bony fusion particularly in intervertebral spinal fusion. The device (10) is formed of bone and has an at least partially demineralized portion (16) between two rigid bone portions (12 and 14) creating an area of flexibility. In one application, the area of flexibility may be used to move the device between a reduced size insertion configuration (Fig. 2) and an expanded implanted configuration (Fig. 3). In another use, the area of flexibility may be useful to dampen shock applied to the implant (Fig. 8). A method is also disclosed for making the implants and inserting the implants into an intervertebral disc space to promote interbody fusion.</p> |
