Bone replacement material |
摘要 |
A bone replacement material for use in a treatment for repairing a vertebral body compression fracture is formed into a pellet having a roughly polyhedral shape. Each pellet having the roughly polyhedral shape has a pair of opposite surfaces, in which one of the opposite surfaces is inclined with respect to the other surface for a predetermined angle. The angle is preferably in the range of 10 to 60°. Further, the volume of each pellet of the bone replacement material 1 is in the range of 13 to 239 mm3. Furthermore, the bone replacement material is formed of calcium phosphate based compound having the Ca/P ratio of 1.0 to 2.0. By using such a bone replacement material, it is possible to carry out packing operation of the bone replacement material into a collapsed vertebral body smoothly, reliably and safely.
