Abstract
This application provides a novel unitary bone implant having at least one rigid, mineralized bone segment, which may be machined to include threads, grooves, a driver head, perforations, a recess, or a symmetric shape, and a flexible, demineralized segment, which may also be machined to any desired shape prior to demineralization, or after demineralization. The disclosed implant has wide orthopedic applicability, including but not limited to repair or replacement of ligaments, tendons, and joints and for inducing vertebral fusions and fractured bone repair.
