Bone repair composition including a bone repair material suspended in a mixture of non-random poly(oxyalkylene) block copolymer and water exhibiting reverse phase behavior when the temperature increases from room temperature to body temperature. There are many materials used today for the repair and regeneration of bone defects. Bone is a composite of collagen, cells, calcium hydroxyapatite crystals, and small quantities of other proteins of organic molecules that has unique properties of high strength, rigidity, and ability to adapt to varying loads.
