This present invention discloses a bone implant composition which comprises about 50˜70% by weight of ceramic particles, wherein the ceramic particles composes tricalcium phosphate and bioactive glass; and about 30˜50% by weight of carrier. The carrier provides good ability of operation and shaping, so the bone implant composition can be filled into a human body by various shapes. Because of high ratio of ceramic particles, it can still construct supports even if carrier is degraded within a short time after implanted, which is beneficial for adhesion and growth of new bone cells, and also promotes healing of bone defect.

The invention relates to compositions useful for bone repair and methods of preparing the same. The invention is particularly suitable for bone repair of large bone defects.

A hybrid composite and method for producing a polymer network are provided. The hybrid composite includes nanocrystalline hydroxyapatite (nHA) and polyurethane. The method for producing a polymer network includes reacting nanocrystalline hydroxyapatite (nHA) particles with lysine derived triisocyanate (LTI) to form a nHA/LTI hybrid prepolymer and reacting the prepolymer with a thioketal (TK) diol to form a nHA/poly(thioketal urethane) (PTKUR) hybrid polymer network.

The present invention is directed to compositions containing polymer matrix, fiber and/or additives which are suitable for load bearing applications for medical devices. The matrix can be formed from a group of polymers which resorb inside the body after implantation. These compositions contain reinforcing fibers that are incorporated into a resorbable polymer matrix to improve properties such as mechanical. The reinforcing fibers can be resorbable, non-resorbable, natural, or metallic. Additives can be incorporated into the matrix material or the fibers or both to provide a secondary effect. These additives can be bioceramics to provide an osteoconductive effect; antimicrobial particles such as silver; coloring agents, and radiopaque additives to make the implants visible under fluoroscopy. The additives may also contribute to improve mechanical properties. The Composite composition with Matrix, Fibers and/or additives can provide enhanced functionality of mechanical, Osteoconductive and tailored degradation characteristics that can result in superior properties conventionally not achievable for Bioresorbable composites.
