    • A method for producing a cleaned bone graft with osteoinductivity above 2.0 suitable for transplantation into a human. The first step is sonicating a bone graft in a nonionic detergent in an ultrasonic cleaner at a temperature ranging from about 33°- C to about 37°- C and for a time period ranging from 15 minutes to 2 hours effective to produce a cleaned bone graft essentially free from bone marrow. The bone graft is sonïcated in purified water in an ultrasonic cleaner at a temperature ranging from about 33-Q C to about 37' C a plurality of times to remove the detergent producing a cleaned bone graft. The bone graft is then sonicated in hydrogen peroxide in an ultrasonic cleaner at a temperature ranging from about 33°- C to about 37°- C for a time period ranging from 10 minutes to about 2 hours effective to retain osteoinductivity of the bone graft and again sonicated in purified water in an ultrasonic cleaner at a temperature ranging from about 33°- C to about 3711 C a plurality of times to produce a cleaned bone graft. The final step is sonicating the bone graft in an alcohol at a temperature ranging from 33°- C to 37°- C for 30 minutes to 2 hours, all of the steps being effective to reduce any initially present viruses at least two logs and bacteria at least ten logs and the bone graft is finally sonicated in purified water to remove the alcohol.
    • 一种生物活性高于2.0的清洁骨移植物的方法,适用于移植到人体中。 第一步是将超声波清洗机中的非离子洗涤剂中的骨移植物在约33℃至约37℃的温度范围内超声波处理15分钟至2小时的时间段,以有效地产生清洁的骨骼 移植物基本上不含骨髓。 将骨移植物在超声波清洗机中的纯净水中在约33℃至约37℃的温度范围内多次洗脱,以除去产生清洁的骨移植物的洗涤剂。 然后将骨移植物在超声清洁器中在约33℃至约37℃的温度范围内在过氧化氢中超声处理持续10分钟至约2小时的时间段,从而有效地保持骨移植物的骨诱导能力, 再次在超声波清洗机中,在约33℃至约3711℃的温度范围内,在净化水中超声处理多次以产生清洁的骨移植物。 最后一步是在33℃至37℃的温度范围内将骨移植物在醇中超声处理30分钟至2小时,所有步骤都有效地减少任何初始存在的病毒至少两个原木和细菌 将至少十个原木和骨移植物最终在纯化水中超声处理以除去醇。
