Apparatus and methods of fixating bone include repairing or remodeling a
hard tissue defect with a composite bone structure. The composite bone
structure includes at least two hard tissues or bones and a scaffold
material fixed together by an adhesive component. The apparatus and
methods include positioning the hard tissues/bones, conforming the
scaffold material to at least a portion of a surface of the hard
tissues/bones, contacting the adhesive component with the hard
tissues/bones and the scaffold material, and changing the material state
of the adhesive component to another material state at which the adhesive
component fixes together the hard tissues/bones and the scaffold
material, thereby forming a composite bone structure having a desired
rigidity.
