POLYMERIC BONE DEFECT FILLER

摘要

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.
