Abstract: 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.

Abstract: A bone repair composition and methods thereof include bone fibers made from cortical bone in which a plurality of bone fibers are made into various implant shapes conducive to introduction into a patient through minimally invasive surgery. The bone fiber compositions may be in the form of a pellet or cylinder. A method includes producing the bone fiber graft efficiently with control of key parameters of cohesiveness, rehydration and swelling of the bone fiber graft. Another method includes introducing the bone fiber graft into the cannula efficiently. A method is also provided to allow introduction of a bone graft into a patient by placing the implant in a tube and expelling it through the action of a plunger.
