Authors made a clinical analysis on 17 patients who were reconstructed with autogenous cranioplasty using refrigerated bone flap at the Department of Neurosurgery, Yonsei University College of Medicine from March 1982 to April 1984, and the results were summarized as follows; 1) The use of refrigerated autogenous bone flap for cranioplasty provided best cosmetic appearance due to natural contour and early operation within 3 months. 2) This procedure was simple with reduction of operating time. No infection nor foreign body reactions were found. 3) There were psychological benefits due to use of autogenous bone flap and radiodensity was appropriate for diagnosis and treatment. Cranioplasty using refrigerated bone flap was thought to be safe and ideal procedure.

I had an opportunity to visit U.S. Naval Tissue Bank and observed tissue procurement and preservation by freeze-drying method and its clinical application while I stayed in the Naval Hospital, Bethesda in 1954. The freeze-dried tissues, especially bone graft, has shown excellent bone repair experimentally and clinically. Recently the mechanisms of osteoinduction have observed by many researchers and isolated the substance, bone morphogenetic protein, and clarified the interaction between BMP and the determined or inducible osteoprogenitor cells.

bone grafting has a broad range of applications and also limitations, thought it is the oldest and most important reconstructive techniques in the oral and maxillofacial surgical field. Further understanding of bone healing mechanism, bone physiology and bone biology, transplantation immunology, and development of tissue banking procedure has enabled oral and maxillofacial surgeons to reconstruct even the most difficult bony defects successfully with the preserved allogeneic bone implant. Now autogenous bone and allogeneic bone implants present a wide variety of surgical options to surgeons, whether used separately or in combination. The surgeons are able to make judicious and fruitful choices, only with a through knowledge of the above-mentioned biologic principles and skillful techniques. The author evaluated 116 cases where allogeneic bones were transplanted for oral and maxillofacial reconstruction.]]>

This study was performed to evaluate the effect of freeze-dried bone graft on space-making capacity and bone formation in the procedure of guided bone regeneration with titanium reinforced ePTFE membrane. After decortication in the calvaria, GBR procedure was performed on 8 rabbits with titanium reinforced ePTFE membrane filled with human FDBA(Rocky Mountain Tissue Bank, Aurora Co., USA). Decortication was performed to induce the effect of bone forming factor from bone marrow. The animals were sacrificed at 2 weeks, 4 weeks, 8 weeks and 12 weeks after the surgery. Non-decalcified specimens were processed for histologic analysis. The results of this study were as follows: 1. Titanium reinforced-ePTFE membrane was biocompatable and capable of maintaining the space-making. 2. FDBA particle was surrounded with connective tissues but there was no evidence on new bone formation. 3. FDBA particle resorbed continuously but it remained until 12weeks after the surgery. Within the above results, TR-ePTFE membrane could be used effectively for Guided bone regeneration but It was assumed that FDBA does not appear to contribute to bone formation.

The courses of the progression in the fibrous dysplasia are characterized by asymptomatic progression or spontaneous regression in some cases after the growth has ceased and the aims of treatment for a fibrous dysplasia are prevention of the pathologic fractures and correction of the deformities. The osteogenic potentiality of the cambium layer in the periosteum and the beneficial effect on the osteogenesis of the impregnating bone graft with autologous red marrow are well documented. We experienced an extensive fibrous dysplasia with cortical thinning and pathologic fracture and it was managed with subperiosteal combined xenograft of Kiel bone with autologous red marrow for the induction of cortical thickening and prevention of the pathologic fractures because of the inoperability of curettage due to extensive lesion over the entire femur, limitations in obtaining large amount of autogenous cancellous bone for the graft and lack of the facilities of the bone bank. This subperiosteal composite xenograft with autologous red marrow for a fibrous dysplasia gave an excellent result of a remarkable cortical thickening and we think this can be a type of management for a entensive fibrous dysplasia. So we are reporting this case with bibliographic reviews.

bone loss was found. Therefore, surgical treatment was performed. After surgical exposure of the defect, granulation tissue was removed and implant surface was treated using tetracycline and chlorhexidine. Then, the flaps were sutured. The wound healing was performed in a non-submerged mode. The present finding demonstrates stable results without progression of bone loss. In one subject, deep V shaped bone defect was filled with bone substitute (ICB, CanCellous Bone, Rockey Mountain Tissue Bank, USA), and resorbable membrane (Lyoplant(R), B.Braun Aesculap AG, Germany) was placed over the grafted defect and healing abutment was connected. However, the inflammation was not resolved and more bone loss was found. At one month after regenerative surgery, the implant was removed.]]>

Since surgical bone banks were set up at several university hospitals in early 1970s, the number of allograft is getting increased in Korean society. Most orthopedic surgeons have used allografts supplied by their own surgical bone banks for tumor reconstruction, arthroplasty, and ligament reconstruction. In 2000, a nation-wide survey for surgical bone banks was performed by Korean orthopedic Association. The questionnaires were prepared by the Committee on Tissue Bank in the Association, and sent to 110 university and training hospitals. Fifty-six surgical bone banks were encountered. However, facilities of the banks were not updated. Most of them were using one or two deep freezers only. Most of them do not have a full-time technician. While most bone banks were using surgically excised femoral heads and amputated limbs, some banks retrieved the tissues from cadaver or organ donors. Since the law for organ transplantation from brain death was established in February 2000, the number of allograft transplantation is growing tremendously. In order to secure the safety of allograft transplantation, the enactment of "the Law for Tissue Transplantation" is mandatory. Unlike organs, the tissues can be procured and stored in advance and can be used whenever they are needed by establishing and operating a form of tissue bank. Therefore, since it is difficult to regulate or supervise tissue banking by "the Law on the Organs and Transplantation", the enactment of a separate law is highly recommended. The government should set the certification standards for the bone and tissue banks suitable for the domestic circumstances. The request of certification of bone and tissue banks should be obtained by the banks that are currently in operation. Also, actual inspection team should be organized involving the professionals and public officers. This team will be responsible for audit of the banks. The certified bone and tissue banks should renew by paper review or actual inspection every 2~3 years. For safe and smooth operation of the banks, the licence system for certified tissue bank specialist(CTBS) should be adopted. Requirements such as academic requirement or professional experience in bone and tissue banks for a certain period of time will be needed.

Progress in medical science and cell biology has resulted in the transplantation of human cells and tissues from on human into another, facilitating reproduction and the restoration of form and function, as well as enhancing the quality of life. For more than 40 years, society has recognized the medical and humanitarian value of donation and transplanting organs and tissues. The standard operating procedures of hard tissues reflect the collective expertise and conscientious efforts of tissue bank professionals to provide a foundation for the guidance of tissue banking activities. Procurement of allograft tissues from surgical bone donors is a part of tissue banking. During the past decades the use of bone allografts has become widely accepted for the filling of skelectal defects in a variety of surgical procedures. In particular in the field of orthopaedic and oral and maxillofacial surgery the demand for allografts obtained from either living or post-mortem donors has increased. Hospital-based tissue banks mainly retrieve allografts from living donors undergoing primary total hip replacement for osteoarthritis or hemi arthroplasty for hip fractures and orthgnatic surgery such as angle reduction. Although bone banks have existed for many years, the elements of organized and maintaining a hospital bone bank have not been well documented. The experience with a tissue bank at Korea Tissue Bank(KTB) between 2001 and 2004 provides a model of procurement, storage, processing, sterilization and documentation associated with such a facility. The following report describes the standard operating procedures of hard tissues such as femoral head obtained from living donors.

To repair bony defects with transplanted bone in the body, fresh autogenous bone is undoubtly. A retrospective study was made of a consecutive patient who underwent mandibular reconstruction with PMCB and allogeneic mandibular crib in November 1996. Free autogenous iliac bone in the form of particulate cancellous bone and marrow was densely packed into the allogenous mandibular crib that was adapted to bridge the mandibular discontinuity defect. Freeze dried allogenous mandibular bone was traded by Wonkwang bone bank. Freeze dried allogenous mandibular bone was used as allogeneic crib carrying the PMCB. This case was undergone successful healing with the formation of a continuous bony union with the remaining mandible. The rate of resorption was assessed by sequeal panoramic radiographs, that is, a day of postoperative period, 3 months of postoperative period, 6 months of postoperative period, 12 months of postoperative period. The mean horizontal dimension of the mandibular defect was 58mm and the mean vertical dimension of the reconstructed segments was 30mm. The bony height reconstructed segments retained about 78% of the bony height of a 1-year period. We estimated that autogenous PMCB grafts and allogenous crib grafts were the most successful and esthetic grafts in mandibular discontinuity reconstruction.

Limb salvage surgery for treatment of malignant bone tumors is an acceptable alternative to amputation in most patients as marked improvement has been achieved in diagnostic imaging, neoadjuvant chemotherapy, and operative techniques. There are several options for limb salvage: endoprosthesis, allograft, treated autobone, etc and each has its own advantages and disadvantages. Prosthetic replacement is an option for limb salvage surgery, but loosening, breakage, and wear are encountered during long-term follow up. Allografts require a large scale bone bank system, and there are concerns of immunologic responses, transmission of disease, religious and social circumstance, and high complication rate. Low heat treated autobone graft are reasonable option of treated autobone. Multiple studies and clinical application of heat treated bone proved the superiority of low heat treated bone(pasteurization, heating at 60 degrees ... to 65 degrees ... for 30 minutes) over other methods of heat treatment such as autoclaving or boiling. Low heat treatment has a lethal effect on malignant cells while preserving sufficient biomechanical strength and bone inducing property. Low heat treatment showed satisfactory results of bone remodeling and union, function, complication (fracture, infection and bone resorption). Several studies suggest that low heat treatment(pasteurization) may be superior to other cell-lethal treatment for autologous bone graft used for limb salvage surgery.
