ABSTRACT:
The invention is directed to a method of debriding bone including incubating the bone and associated soft tissue, with one or more debriding solutions where the debriding solution may include one or more alkaline solutions. Incubation is optionally carried out with one or more debriding agents including inert dry granular or particulate material including for example beads, and the granular phase of an alkaline agent, including for example granular sodium hydroxide. The incubating may be carried out with agitation. In another embodiment, the medullary canal of the bone is subjected to a positive pressure stream of debriding solution under conditions sufficient to loosen the associated soft tissue from the bone at the interface of the soft tissue and bone. In a further embodiment, the debriding solution is provided as a gel.
