The tissues can then be stored at room temperature buy 500 mg relafen mastercard, but require rehydration prior to implantation buy 500 mg relafen with visa. Lyophilization destroys most of the osteoprogenitor cells, but cancellous and cortical structure is retained. Fresh o frozen tissues are stored at −20 to −80 C, and simply require thawing and washing prior to implantation. Answer: A—Mechanical strength is one of the four elements necessary for bone reformation, and is reduced when bone is lyophilized. Freezing and procedures to lyophilize bone allografts both reduce the immunogenicity (Answer B) of the graft. Lyophilization does not signifcantly reduce the healing properties of bone over freezing. The risk of infectious disease transmission (Answer E) from fresh frozen allografts is greater than in tissue that has been processed for lyophilization; however, current donor eligibility criteria have signifcantly reduced the risk of infectious disease transmission from either type of bone. The lower risk of infectious disease transmission from lyophilized bone needs to be weighed against the loss of strength when replacing a large defect, especially if the defect involves a load bearing structure. Osteoconductivity and osteoinductivity (Answers C and D) are not different between fresh frozen and lyophilized tissue. The manufacturer’s instructions for use of a freeze-dried (lyophilized) tendon have been lost. The operating room nursing staff contacts the director of the hospital tissue service for guidance. Any portion of the tendon not implanted can be returned for future implantation C. Manipulate the product continuously during rehydration Concept: All purchased tissues are supplied with manufacturer’s instructions for the preparation of the tissue prior to implantation. These instructions follow certain general principles based on tissue type, and if the instructions are missing, the tissue may still be used successfully if these principles are followed. Surgeons can override the tissue preparation instructions provided by the manufacturer, but the tissue service Medical Director is not in a position to do so.
