摘要：PROBLEM TO BE SOLVED: To provide a bone jointing screw made of a bone, which shows excellent early fixation characteristics and accelerates biological fusion. SOLUTION: The bone jointing screw made of a bone is formed by smoothing a surface part of a bone which is cut out and shaped into a screw shape by plasma processing to a degree not to modify bone morphogenic factors. The bone jointing screw made of a bone increases a contacting performance with female threads while keeping a small torque in screwing, improves the early fixation at a site of a bone fracture, and accelerates the fusion by helping or promoting the growth of bone cells from the contacting part by bone morphogenic factors inside the screw.
