Abstract: 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 sonicated in purified water in an ultrasonic cleaner at a temperature ranging from about 33° C. to about 37° C. a plurality of times to remove the detergent producing a cleaned bone graft.
