摘要：
Compositions and methods thereof include bone fibers made from cortical bone in which a plurality of bone fibers are made into shapes that are used to augment fixation of orthopedic implants and screws. Sheets of bone fibers may be used as an interface between bone and tissue, tendons, and/or ligaments. Cylindrical shaped implants that may be placed in drilled holes in bone prior to screw placement to enhance fixation of the screw. The physical presence of the fibers provides initial fixation, while the use of an osteoinductive material provides long term enhancement of bone formation around the screw and hence fixation. The bone fiber compositions may be in the form of a cylinder or a tube. A delivery system and methods of use are also provided.
