Injectable, ready-to-use two-paste cement-forming compositions comprise a first paste and a second paste. The first paste comprises a non-aqueous oil-based suspension of monocalcium phosphate monohydrate (MCPM) powder, at least one surfactant effective to improve compatibility of the oil and the MCPM, and an organic acid, with an oil to MCMP powder weight ratio of about 0.2 to about 0.5. The second paste comprises an aqueous suspension of -tricalcium phosphate (-TCP) powder and a gel-forming polymer, with a water to -TCP powder weight ratio of about 0.3 to about 0.5. The molar ratio of -TCP powder to MCPM powder is greater than 1. An article of manufacture comprises a first compartment in which the first paste is contained, and a second compartment in which the second paste is contained. The compositions are useful for bone repair or replacement.

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.

A biphasic calcium phosphate/hydroxyapatite (CAP/HAP) bone substitute material having a sintered CAP core and at least one closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core, whereby the epitactically grown nanocrystals have the same size and morphology as human bone mineral, wherein the closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core has a non-homogeneous external surface comprising individual clusters of flat crystal platelets consisting of epitactically grown HAP nanocrystals and coarse areas between the individual clusters, whereby the percentage of the coarse areas between the individual clusters as measured by SEM is at least 20% of the total surface, which material shows an increased capacity to induce bone formation, and a process of preparation thereof.

Compositions of, methods of making, and methods of using alkaline earth phosphate bone cements are disclosed. A bone cement composition includes a powder comprising a basic source of calcium, magnesium, or strontium, a setting solution comprising H3PO4 and a buffer, and a biocompatible polymer that is incorporated into the setting solution. The powder is mixed with the setting solution to form a bone cement paste that either (a) sets into a hardened mass, or (b) is irradiated with electromagnetic radiation to form dry powders, the dry powders then being mixed with a second setting solution to form a radiation-assisted bone cement paste that sets into a hardened mass.

A biphasic calcium phosphate/hydroxyapatite (CAP/HAP) bone substitute material having a sintered CAP core and a closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core, wherein the closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core has a homogeneous coarse external surface comprising flat crystal platelets, which shows an enhanced osteogenic response, a method of promoting bone formation, bone regeneration and/or bone repair by implanting the biphasic calcium phosphate/hydroxyapatite (CAP/HAP) bone substitute material, and a process of preparation thereof.

Provided herein is technology relating to lipid compositions containing bioactive fatty acids and particularly, but not exclusively, to compositions and methods related to the production and use of structured lipid compositions containing sciadonic and/or pinoleic acid alone or in combination with other bioactive fatty acids including, but not limited to, eicosapentaenoic acid, docosahexaenoic acid, conjugated linoleic acid, and non-?-oxidizable fatty acid analogues such as tetradecylthioacetic acid.

Biomaterials, implants made therefrom, methods of making the biomaterial and implants, methods of promoting bone or wound healing in a mammal by administering the biomaterial or implant to the mammal, and kits that include such biomaterials, implants, or components thereof. The biomaterials may be designed to exhibit osteogenic, osteoinductive, osteoconductive, and/or osteostimulative properties.

Sliceable bone repair material is a porous block-shaped scaffold containing a hydrogel, wherein the hydrogel is formed by Michael type addition of at least two precursor molecules. Said scaffold is made of a synthetic ceramic material and has interconnected macropores having a diameter above 100 m. In addition said scaffold has a total porosity of 60 to 80%. The total volume of the hydrogel is smaller than the total volume of the interconnected macropores.
