[Demineralized bovine bone matrix: diffractional characterization].

Abstract – Calf femoral bone was submitted to demineralization in order to test the ability of demineralized bone matrix to induce new bone formation when implanted in spinal arthrodesis. High and small angle X Ray Diffraction techniques have been used to follow the structural modifications which take place during the demineralization process. The results indicate that neither the demineralization nor the gamma Ray sterilization, affect the molecular structure of collagen, while its fibrillar structure appears highly after demineralization.
