A spinous metal granule (1) is provided. The outline of the spinous metal granule (1) is spherical, cylindrical or polyhedral and is 2 to 15mm in size and the spinous metal granule (1) is provided with spinous structure (2) like a urchin or dentrite. When in use, an appropriate number of spinous metal granules (1) of appropriate size and shape are selected by a doctor to be mixed and stirred with the autogenous or allogeneic broken bone granule and bone paste (3) of a patient to form a mixed filler, which is filled in the bone defect and is pressed and tamped to be initially stabilized. In the recovery process after an operation, the surrounding sclerotins and the bone paste (3) and broken granules surrounding the spinous metal granule (1) are fused to grow into a whole to form a relatively stable and biologically active support structure. Meanwhile, such support structure can further stimulate the surrounding blood supply to promote the repairing of the damaged cartilage. |
