A method for controlling generation of biologically desirable voids in a composition placed in proximity to bone or other tissue in a patient by selecting at least one water-soluble inorganic material having a desired particle size and solubility, and mixing the water-soluble inorganic material with at least one poorly-water-soluble or biodegradable matrix material. The matrix material, after it is mixed with the water-soluble inorganic material, is placed into the patient in proximity to tissue so that the water-soluble inorganic material dissolves at a predetermined rate to generate biologically desirable voids in the matrix material into which bone or other tissue can then grow.

The present disclosure provides a bio-material composition and method of use in craniomaxillofacial surgery. An example method comprises: accessing a space defined between adjacent bone structures in a head of a patient; mixing magnesia, potassium biphosphate, and a calcium phosphate with an aqueous solution to form an activated bone fusion slurry (ABFS); applying an effective amount of the ABFS to the space between the adjacent bone structures; allowing the ABFS to set forming a bonded bone structure; and permitting bone growth into the bonded bone structure providing fusion of the two adjacent bone structures, wherein the ABFS promotes fusion of the two adjacent bone structures without the need for additional physical fixation devices.

The present invention provides a means effective for bone regeneration or bone augmentation.

Provided is a method of bone regeneration or bone augmentation, comprising: implanting a porous composite at a site in need of the bone regeneration or bone augmentation, and administering parathyroid hormone (PTH) to a subject in need of the bone regeneration or bone augmentation, wherein the porous composite comprises calcium phosphate.

A medical instrument in which an inorganic salt solid such as apatite into which a peptide hormone or the like is embedded is placed so that a metal or the like is coated therewith, in which the inorganic salt solid is provided by controlled delay co-precipitation or the like in an unstable supersaturated calcium phosphate solution, and the medical instrument is exposed to ionizing radiation at a dose sufficient for sterilization.

Provided is an orthopedic composition, including: a powder composition including calcium sulfate hemihydrate, β-tricalcium phosphate and hydroxypropyl methylcellulose; and a solvent including glycerol and water. The orthopedic composition exhibits improved washout resistance. A method of manufacturing the orthopedic composition and a bone graft set including the orthopedic composition are further provided.

In described embodiments, the present invention includes a magnesium-based composite material formed from a plurality of -phase magnesium grains; and a -alloy phase comprising magnesium and nano-diamond and/or and phosphate containing nanoparticles, the -alloy phase surrounding each of the plurality of magnesium grains. A method of manufacturing a composite material is also disclosed.

The present disclosure discloses a fracture repair device realizing transition from mechanical fixation (association of osteosynthesis, AO) to biological fixation (biological osteosynthesis, BO), including: a bone repair instrument, wherein auxiliary components are arranged at positions, close to a repaired bone surface, of the bone repair instrument, and each auxiliary component is made of a degradable metal material or a composite material thereof or a degradable polymeric material. The device of the present disclosure only has the advantages of AO rigid mechanical fixation, but also can effectively improve the defects of bone disconnection, fixed segment osteoporosis, re-fracture after defixation, etc., frequently occurring under AO rigid mechanical fixation, realizing transition from mechanical fixation (association of osteosynthesis, AO) to biological fixation (biological osteosynthesis, BO) during bone fixation or repair.
