Abstract: A bone defect filler for implantation in a bone defect of a patient includes a particulate polymer distributed within a polymeric binder. The particulate polymer includes a plurality of particles, which may have substantially the same material composition as the polymeric binder. The particles of the particulate polymer may be formed in a variety of shapes and/or sizes to provide the bone defect filler with improved pore interconnectivity, material expansion and contamination characteristics, while maintaining sufficient mechanical strength and handling characteristics for bone repair applications. The bone defect filler also provides the flexibility to be molded or shaped in situ to fill the bone defect.

Abstract: A bone repair apparatus includes a partially polymerized biocompatible adhesive provided in a state wherein polymerization of the biocompatible adhesive is substantially suspended. A method for repairing a bone defect includes preparing the biocompatible adhesive, suspending polymerization of the biocompatible adhesive prior to full cure, delivering the biocompatible adhesive to the bone defect while polymerization is substantially suspended and accelerating polymerization of the biocompatible adhesive to achieve full cure. The method provides an implanted biocompatible adhesive with a malleable osteoconductive structure without compromising the physical characteristics of the biocompatible adhesive, thereby improving handling and delivery of the bone adhesive.

Abstract: A pedicle fastener for implantation during a spinal fusion procedure includes a head and shank, the shank being connectable to the head and extending outwardly therefrom. The shank may include a shielding feature formed therein for accommodating an adhesive augmenting the pedicle fastener and improving implantation strength and stiffness thereof. A method for implanting the pedicle fastener includes forming a hole in a pedicle, applying the adhesive to the hole and sliding the shank of the pedicle fastener into the hole. The adhesive may also be applied to the hole through direct injection, injection through a longitudinal cannula formed in the pedicle fastener or by depositing the adhesive on the shank and inserting the shank into the hole. Polymerization of the adhesive may be accelerated by heating the pedicle fastener.
