The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
Transplantation of an individual's own tissue from one site to another site.
The transference of a heart from one human or animal to another.
The transference of either one or both of the lungs from one human or animal to another.
The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.
The transfer of STEM CELLS from one individual to another within the same species (TRANSPLANTATION, HOMOLOGOUS) or between species (XENOTRANSPLANTATION), or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). The source and location of the stem cells determines their potency or pluripotency to differentiate into various cell types.

Transference of an organ between individuals of the same species or between individuals of different species.
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

The transference of a pancreas from one human or animal to another.
Individuals supplying living tissue, organs, cells, blood or blood components for transfer or transplantation to histocompatible recipients.
The transference of pancreatic islets within an individual, between individuals of the same species, or between individuals of different species.
Transference of a tissue or organ from either an alive or deceased donor, within an individual, between individuals of the same species, or between individuals of different species.
A general term for the complex phenomena involved in allo- and xenograft rejection by a host and graft vs host reaction. Although the reactions involved in transplantation immunology are primarily thymus-dependent phenomena of cellular immunity, humoral factors also play a part in late rejection.
Transference of cells within an individual, between individuals of the same species, or between individuals of different species.
An organism that, as a result of transplantation of donor tissue or cells, consists of two or more cell lines descended from at least two zygotes. This state may result in the induction of donor-specific TRANSPLANTATION TOLERANCE.
Tumors or cancer located in bone tissue or specific BONES.
The growth and development of bones from fetus to adult. It includes two principal mechanisms of bone growth: growth in length of long bones at the epiphyseal cartilages and growth in thickness by depositing new bone (OSTEOGENESIS) with the actions of OSTEOBLASTS and OSTEOCLASTS.
Diseases of BONES.
The clinical entity characterized by anorexia, diarrhea, loss of hair, leukopenia, thrombocytopenia, growth retardation, and eventual death brought about by the GRAFT VS HOST REACTION.
Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.
Transplantation between genetically identical individuals, i.e., members of the same species with identical histocompatibility antigens, such as monozygotic twins, members of the same inbred strain, or members of a hybrid population produced by crossing certain inbred strains.

An induced state of non-reactivity to grafted tissue from a donor organism that would ordinarily trigger a cell-mediated or humoral immune response.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Extracellular substance of bone tissue consisting of COLLAGEN fibers, ground substance, and inorganic crystalline minerals and salts.
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.

Support of the anterior column with allografts in tuberculosis of the spine. (1/1358)

Fresh-frozen allografts from the humerus were used to help to stabilise the spine after anterior decompression for tuberculosis in 47 children with a mean age of 4.2 years (2 to 9). The average angle of the gibbus, before operation, was 53 degrees; at follow-up, two years later, it was 15 degrees. Rejection of the graft or deep sepsis was not seen. Cross trabeculation between the allograft and the vertebral body was observed at six months, with remodelling occurring at approximately 30 months.  (+info)

Mechanical considerations in impaction bone grafting. (2/1358)

In impaction grafting of contained bone defects after revision joint arthroplasty the graft behaves as a friable aggregate and its resistance to complex forces depends on grading, normal load and compaction. Bone mills in current use produce a distribution of particle sizes more uniform than is desirable for maximising resistance to shear stresses. We have performed experiments in vitro using morsellised allograft bone from the femoral head which have shown that its mechanical properties improve with increasing normal load and with increasing shear strains (strain hardening). The mechanical strength also increases with increasing compaction energy, and with the addition of bioglass particles to make good the deficiency in small and very small fragments. Donor femoral heads may be milled while frozen without affecting the profile of the particle size. Osteoporotic femoral heads provide a similar grading of sizes, although fewer particles are obtained from each specimen. Our findings have implications for current practice and for the future development of materials and techniques.  (+info)

Evaluation of the allograft-prosthesis composite technique for proximal femoral reconstruction after resection of a primary bone tumour. (3/1358)

OBJECTIVE: To evaluate clinical and functional outcomes resulting from the allograft-composite technique used for proximal femoral osteoarticular reconstruction in patients who had limb salvage surgery for primary bone tumours. DESIGN: A retrospective review of a prospectively gathered database to provide a descriptive study. SETTING: A tertiary care musculoskeletal oncology unit in a university hospital. PATIENTS AND INTERVENTIONS: Patients treated between 1987 and 1993 were eligible for inclusion in this study if they met the following criteria: they were treated surgically for a primary malignant bone tumour; and a proximal femoral allograft-implant composite technique was used for the reconstruction. MAIN OUTCOME MEASURES: Major postoperative complications with emphasis on mechanical complications in the reconstructive composite implant. Functional outcome in a subset of patients using the 1987 and 1994 versions of the Musculoskeletal Tumor Society instrument, the Short-Form-36 and the Toronto Extremity Salvage Score. RESULTS: There were 5 mechanical and 2 infectious complications requiring surgical intervention. Functional scores were generally low. CONCLUSIONS: Our results suggest that the perceived benefits of the composite technique may accrue only to a few patients, partly owing to the risk of mechanical complications. Although these can be reduced by avoiding the use of cement in the host femur, the generally poor functional outcomes suggest that this technique needs to be studied further in this group of patients and compared with other reconstructive techniques, particularly the prosthetic implant.  (+info)

Bone-peg grafting for osteochondritis dissecans of the elbow. (4/1358)

In the treatment of osteochondritis dissecans involving the elbow, we have used a bone-peg graft taken from the proximal part of the ulna and inserted into the defect. Thirty-two patients were followed from 2 to 10.5 years. The graft was utilised in 20 elbows, and 6 of these also had concomitant removal of a loose body. Another 6 elbows had removal of a loose body only. Ten elbows were treated conservatively in 5 of these the outcome was unsatisfactory, including 4 in which a bone-peg graft was later necessary. The bone-peg graft gave the best short-term results. Bony union of the dissecans site and reconstitution of subchondral bone required an average of 6.5 months. In 15 patients followed for a minimum of 5 years, the bone-peg graft was effective in limiting the development of osteoarthritis. Bone-peg grafting is a reliable method for treating osteochondritis dissecans of the elbow.  (+info)

Salvage of the head of the radius after fracture-dislocation of the elbow. A case report. (5/1358)

We describe a patient with a Mason type-III fracture of the head of the radius associated with traumatic dislocation of the elbow. The radial head was intact throughout its circumference despite being completely detached from the shaft and devoid of any soft-tissue attachments. Severe comminution of the radial neck prevented reconstruction by internal fixation and precluded prosthetic replacement of the head. The head was fixed to the shaft with a tricortical iliac-crest bone graft which replaced the neck. Two years later, the patient had a stable elbow with flexion from 10 degrees to 130 degrees. Radiologically, the head of the radius appeared to be viable and the bone graft had incorporated.  (+info)

The pathology of bone allograft. (6/1358)

We analysed the histological findings in 1146 osteoarthritic femoral heads which would have been considered suitable for bone-bank donation to determine whether pathological lesions, other than osteoarthritis, were present. We found that 91 femoral heads (8%) showed evidence of disease. The most common conditions noted were chondrocalcinosis (63 cases), avascular necrosis (13), osteomas (6) and malignant tumours (one case of low-grade chondrosarcoma and two of well-differentiated lymphocytic lymphoma). There were two with metabolic bone disease (Paget's disease and hyperparathyroid bone disease) and four with inflammatory (rheumatoid-like) arthritis. Our findings indicate that occult pathological conditions are common and it is recommended that histological examination of this regularly used source of bone allograft should be included as part of the screening protocol for bone-bank collection.  (+info)

Histopathology of retrieved allografts of the femoral head. (7/1358)

From November 1994 to March 1997, we harvested 137 grafts of the femoral head from 125 patients for donation during total hip arthroplasty according to the guidelines of the American Associations of Tissue Banks (AATB) and the European Association of Musculo-Skeletal transplantation (EAMST). In addition to the standards recommended by these authorities, we performed histopathological examination of a core biopsy of the retrieved bone allograft and of the synovium. Of the 137 allografts, 48 (35.0%) fulfilled all criteria and were free for donation; 31 (22.6%) were not regarded as suitable for transplantation because the serological retests at six months were not yet complete and 58 (42.3%) were discarded because of incomplete data. Of those discarded, five showed abnormal histopathological findings; three were highly suspicious of low-grade B-cell lymphoma, one of monoclonal plasmacytosis and the other of non-specific inflammation of bone marrow. However, according to the standards of the AATB or EAMST they all met the criteria and were eligible for transplantation. Our findings indicate that the incidence of abnormal histopathology in these retrieved allografts was 3.6%. Since it is essential to confirm the quality of donor bones in bone banking, we advise that histopathological screening of donor bone should be performed to exclude abnormal allografts.  (+info)

Multi-bracket appliance in management of mandibular reconstruction with vascularized bone graft. (8/1358)

BACKGROUND: The most commonly used tool for maxillo-mandibular fixation to the patient who underwent reconstruction using a vascularized bone graft after mandibular resection is a dental arch-bar. However, the occlusal relationship achieved by this method is not ideal. Different from the dental arch-bar, the multi-bracket appliance which is frequently used in orthodontic treatment can control the position of each individual tooth three dimensionally. Thus, this appliance was applied for maxillo-mandibular fixation to patients who underwent mandibular reconstruction using a vascularized bone graft. METHODS: A multi-bracket appliance was applied to three patients. Prior to the surgery, standard edgewise brackets were bonded to the teeth in the maxilla and in the remaining mandible. After mandibular resection, wires for maxillo-mandibular fixation were applied. The harvested bone was then carefully fixed with miniplates to maintain the occlusion. The multi-bracket appliance was worn for 3 months when the wound contraction became mild. RESULTS: All three cases demonstrated stable and good occlusion. They also demonstrated satisfactory post-surgical facial appearance. CONCLUSIONS: Compared to conventional dental arch-bars, a multi-bracket appliance offers improved management of mandibular reconstruction. Firstly, its properties are helpful in maintaining occlusion of the remaining dentition accurately in bone grafting procedure as well as protecting against postsurgical wound contraction. Secondly, the multi-bracket appliance keeps the oral cavity clean without periodontal injury. As a result, stable occlusion of the residual teeth and good facial appearance were obtained.  (+info)

We undertook this study to determine the results of acetabular fixation using the Duraloc 300 uncemented acetabular component combined with impaction bone grafting in patients with acetabular protrusion. Forty-two consecutive total hip replacements using a Duraloc 300 cup in patients with acetabular protrusion requiring impaction bone grafting were reviewed at an average of 6.3 years. In no cases were structural graft, wire mesh or cages utilised. Pre-operative X-rays were analysed for degree of protrusion. Post-operative X-rays were analysed for cup placement including centre of rotation and interface gaps. Follow-up films were analysed for graft incorporation, lucent lines, osteolysis, wear and migration. Kaplan-Meier survivorship analysis was ...
Purpose: To evaluate the effectiveness and limitations of autologous osteochondral grafting for the treatment of articular cartilage defects in the knee. Methods: The subjects were 40 patients who had undergone autologous osteochondral grafting. Fifteen knees had cartilage defects combined with anterior cruciate ligament tears (ACL group), 15 knees had cartilage defects combined with osteoarthritis (OA group), and 10 knees had cartilage defects combined with osteochondral dissecans (OCD group). From one to five osteochondral pegs were harvested from the less-weight-bearing periphery of the articular surface of the femoral condyle and grafted to cartilage defects. The clinical results were assessed based on the Lysholm score and radiographic and magnetic resonance imaging (MRI) image assessment. Results: The median follow-up duration was 24 months (range from 12 to 41 months). The mean Lysholm score following treatment was improved in all groups. The patients who had cartilage defects combined ...
BACKGROUND: Nonunion of long bones in lower limbs is a common complication of orthopedic trauma that can be extremely debilitating. This retrospective study describes our experience using expandable intramedullary nails and autologous bone grafting in treating lower limb long bone nonunion with bone defects.. METHODS: Nineteen patients (mean age 38.9 years, range 18-61) with lower limb long bone nonunion and defects caused by femoral or tibial fracture types were as follows: A2 (3 femoral, 1 tibial), A3 (1 femoral, 2 tibial), B2 (3 femoral, 4 tibial), and B3 (1 femoral, 4 tibial). Expandable intramedullary nailing and autologous bone (iliac and/or fibular) grafting were used for the treatment. Postoperative bone healing as determined by analysis of standard anteroposterior and lateral X-ray films every 4 weeks. Complications were noted.. RESULTS: The average number of previous surgeries was 1.9 (range 1-4). The mean duration from original injury to treatment was 17.6 months (range 9-40 months). ...

AU - Park, Jong Hoon. AU - Lee, Soon-Hyuck. AU - Park, Jong Woong. PY - 2017/6/18. Y1 - 2017/6/18. N2 - Background Although free-vascularized long-bone transfer is useful for reconstruction of a large segmental bone defect, it is limited by availability of transplantable bone, meticulous microsurgical technique, and donor-site morbidities. Hence, easier, readily available, and safer surgical procedures are warranted. This study evaluated the effects of vascularized small corticocancellous bone grafting for reconstruction of a large segmental rabbit femur defect. Methods A 1.5 cm defect was created in the femurs of 40 New Zealand white rabbits and divided into a control group ( n = 10, bone defect without graft), group A ( n = 10, bone defect filled with morselized autogenous bone), group B ( n = 10, bone defect grafted ...

Impaction grafting is controversial in the presence of segmental and cavitary acetabular defects and requires the use of supplemental devices to close segmental defects. This approach, however, would allow treating combined deficiencies that could not be managed with impacted cancellous bone alone. We raised the following two questions: (1) What is the survival rate in patients with combined deficiencies reconstructed with metal mesh, impaction grafting and a cemented cup and (2) can metal mesh prevent cup migration? We evaluated 23 cavitary uncontained acetabular defects in revision hip arthroplasty. Preoperative diagnoses were aseptic loosening (19 hips) and second-stage reimplantations after resection for infection (four hips). The preoperative Merle DAubigné-Postel score averaged 7.4 points. Two patients had reoperations for mechanical failure at 6 and 24 months. The survival rate with further revision as an end point was 90.8% at an average of 36 months (range, 24-56 months; 95% ...
Each type of graft material has its benefits. Your periodontist can help you decide which sinus augmentation material is right for you.. Autogenous bone grafts are the historical standard of bone grafting materials. Since the bone comes from your own body, your immune system will readily accept the transferred cells. Because your periodontist will harvest the bone cells from your body, usually from the hip or the tibia bone just below the knee, autogenous bone grafts require two surgeries. Autogenous bone grafts may be the right approach to sinus augmentation for you if you are willing to undergo two procedures and are concerned about rejection.. Allograft or xenograft may be right for you if you prefer to avoid the first procedure to harvest bone cells. During an allograft bone graft, our periodontist will transfer purified bone from a human cadaver. In xenograft, bone will serve as a scaffold onto which your body will grow new bone cells.. Sinus augmentation may be right for you if you are ...
BACKGROUND: In cases when the alveolar crest is too narrow to host an implant, lateral augmentation is required. The use of autogenous bone blocks harvested from the iliac crest is often demanded. One disadvantage is the associated patient morbidity.. PURPOSE: The purpose of this study was to clinically and histologically evaluate the use of morselized impacted bone allograft, a novel technique for reconstruction of the narrow alveolar crest.. MATERIALS AND METHODS: Two patients with completely edentulous maxillae and one partially edentulous, with a mean age of 77 years (range 76-79 years) were included in the study. The alveolar crest width was ,3 mm without possibility to place any implant. Bone grafts were taken from a bone bank in Gävle Hospital. Bone from the neck of femur heads was milled to produce bone chips. The milled bone was partially defatted by rinsing in 37 degrees C saline solution. After compression of the graft pieces with a size of 15 mm (height), 30 mm (length), and 6 mm ...
Packing of bone defect with particulate allografts is a commonly performed clinical procedure. However, the ideal size of bone particles used to fill bone defects is ill-defined. For this reason the study of biology of bone allografts with different particle sizes has been performed. Standard size b …
Recovery of fractures and bone defects normally follows an orderly series of events including formation of a hematoma and an initial stage of swelling, development of soft callus, formation of hard callus, and finally the stage of bone redesigning. of the progenitor cell populace for bone and vascular lineage cells. Autologous bone grafting can provide the necessary scaffold, progenitor and differentiated lineage cells, and biological cues for bone reconstruction, however, autologous bone graft may be limited in amount or quality. These unfavorable conditions are magnified in systemic conditions with chronic swelling, including obesity, diabetes, chronic renal disease, ageing as well as others. Recently, strategies have been devised to both mitigate the necessity for, and complications from, open methods for harvesting of autologous bone by using minimally invasive aspiration techniques and concentration of iliac crest bone cells, followed by local injection into the defect site. More ...
The purpose of this study is to investigate quantitative vascular cone beam CT(CBCT) in a clinical pilot of patients that have received a structural allograft for bone cancer or a vascularized structural autograft for bone cancer or traumatic injury. Development of a minimally invasive, longitudinal outcome measure to quantify intramedullary vascular volume and cortical bone volume of structural allografts in patients is required to translate revitalizing structural allograft in clinical trials. Our novel vascular CBCT will be able to demonstrate the significant differences between vascularized fibular autografts vs. structural allografts in patients that will undergo structural grafting. These data will be used to devise a power calculation for a definitive clinical trial to evaluate the efficacy of the revitalizing allograft ...
Most acetabular revisions are managed with cementless hemispherical or elliptical metal implants relying on bone ingrowth. Nonetheless, loss of acetabular bone stock and inability to achieve secure component fixation represent challenges in the setting of revision total hip arthroplasty. Impaction bone grafting (IBG) using allograft represents one option for treatment of this problem. However, cup migration and bone graft resorption are limitations when IBG is used for large segmental defects, and the precise role of IBG as well as the use of mesh (and the kinds of defects for which mesh does not work well) in this setting remains unknown.. ...
Distal comminuted femoral fractures with joint involvement are highly challenging for the surgeon. We present a potential therapeutic concept that aims especially at the treatment of posttraumatic leg length discrepancy. This case report describes a polytraumatized 19-year-old German woman. Among other injuries she had a third grade open distal comminuted femoral fracture with a long distance metaphyseal osseous defect. As a primary care procedure an external fixation was applied at first. On day 13, an open reconstruction of her distal femur and the articular surface was performed by screw osteosynthesis, shortening and intramedullary nailing. Due to delayed osseous consolidation an autologous cancellous bone grafting was performed twice. In addition to the second cancellous bone graft an allogeneic cortical bone graft was implemented. A 6.5cm posttraumatic leg length shortening after osseous consolidation was the result. The entire leg length shortening was successfully treated 16 months after her
Autograft is considered as the gold standard in bone grafting. However, the development of tissue banks has allowed for a wider use of bone allografts, with good results. Demineralised Bone Matrix (DBM) and recombinant human Bone Morphogenetic Proteins (rh-BMPs) were also introduced to replace the …

DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. DDD patients may also have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). These patients may have had a previous non-fusion spinal surgery at the involved spinal level(s). The device is intended to be used with autogenous bone graft and/or allogeneic bone graft composed of cancellous, cortical, and/or corticocancellous bone and supplemental fixation.. ...
Background: Subchondral bone necrosis is important in osteonecrosis, Mb Kienboeck, intraarticular fractures or osteochondral grafting. As revascularization follows, bone resorption may lead to collapse in load bearing areas during the remodeling. Bisphosphonates are potent osteoclast inhibitors. Our hypothesis was that local bisphosphonate treatment of an osteochondral graft, in a high load environment, would protect the subchondral bone from collapse and maintain the joint architecture during remodeling. To investigate this, we used a rat bone chamber model to subject a necrotic osteochondral graft to a large mechanical load during remodeling. Method: Cylindrical osteochondral grafts were taken from the patellar groove of rats, one end of the cylinder being the joint surface. The grafts were frozen, thawed and treated with alendronate. The length of the cylinder was measured and the grafts were placed in the chambers, which were inserted into the proximal tibia of rats. The chambers were left ...

A method by which immune responses to cortical bone grafts and other substrates (e.g., cement, IPN, etc.) can be minimized and at the same time graft osteoinductive potential can be improved, and improved graft substrate materials are disclosed. The method of the invention provides new types of bone grafts that incorporate into host bone more thoroughly and more rapidly, eliminating long-term complications, such as fracture, non-union, infection, and rejection. In the method of the invention, bone grafts or other substrates are modified to have an osteoinductive surface modification that the recipients body will accept as its own tissue type and therefore will not reject or otherwise cause to fail. The osteoinductive surface modification comprises a biopolymer matrix coating that is seeded with periosteal cells that have been previously harvested either from the graft recipient or from an allogenic or xenogenic donor source.
The present invention is directed to a process for cleaning large bone grafts using a pressure mediated flow of solutions, and to the bone grafts produced thereby where the bone grafts are suitable for transplantation into a human. The present method includes inducing a positive and/or negative pressure-mediated flow of solvent through an opening in the bone shaft of the large bone graft thereby removing bone marrow elements, as well as any bacteria particles and/or virus particles present. The bone grafts produced are suitable for transplantation into a human and are essentially free from viral and bacterial contamination, for example, free from HIV infectious particles.

Good outcomes have been reported in revision total hip replacement with massive segmental defects using impaction bone grafting with circumferential metal meshes. However, the morphology of defects that require a mesh is poorly defined. The purpose of this study was to evaluate the effects of a variety of segmental defects on load transmission to the proximal femur under both axial and rotational loads. Initial stability of the Exeter stem was investigated in a composite bone model using three medial bone defect morphologies: Long (length 5 cm × width 2 cm), Short (2.5 cm × 2 cm), Square (3.2 cm × 3.2 cm), Square with mesh (3.2 cm × 3.2 cm defect covered with metal mesh), and with no defect as control. Specimens (5 per group) were axially loaded and internally rotated up to 20° or to failure. Strain distributions of the femora were measured using a strain gauge. All Square group specimens failed while rotation was increasing. In the other four groups, failure was not observed in any specimens. Mean
Complex skeletal injuries and large bone fractures are still a significant clinical problem in US. Approximately 1.5 million Americans (veterans, their families, and civilians) every year suffer from bone loss due to traumatic skeletal injuries, infection, and resection of primary tumors that require extensive grafting to bridge the gap. The US bone graft market is over $2.2 billion a year. Due to insufficient mechanical stability, lack of vascularity, and inadequate resorption of the graft, patients with traumatic large skeletal injuries undergo multiple costly operations followed by extensive recovery steps to maintain proper bone alignment and length. Current strategies for repairing damaged or diseased bones include autologous or allograft bone transplantations. However, limited availability of autografts and risk of disease transmission associated with allografts have necessitated the search for the development of new bone graft options and strategies. The overall goal of this project is to develop
Purpose: The roles of angiogenesis and osteogenesis in autologous and allogenic bone grafts and the use of platelet-rich plasma (PRP) as a modifier were investigated. Materials and Methods: Forty rabbit mandibles received onlay grafts of fresh autologous and frozen allogeneic bone. PRP was added on the right side. After intervals of 3, 7, 14, 28, and 56 days, the animals were euthanized. Hematoxylin and eosin staining was used to measure the quantity and area of osteoblasts. Sections stained with toluidine blue showed newly formed bone area. In sections with Weigert-van Gieson staining, the number of vessels and their lumens was quantified. The quantity and area of cellular arrangements expressing CD31 and the area of vessels were obtained. Results: Quantities of osteoblasts and their areas, newly formed matrices, and vessels and their lumen areas were obtained and identified by immunomarking with CD31. In general, values for these were higher in rabbits with allogeneic bone grafts and on the ...

In this study, we aimed at developing and validating a technique for the engineering of osteochondral grafts based on the biological bonding of a chondral layer with a bony scaffold by cell-laid extracellular matrix. Osteochondral composites were generated by combining collagen-based matrices (Chondro-Gide) containing human chondrocytes with devitalized spongiosa cylinders (Tutobone) using a fibrin gel (Tisseel). We demonstrate that separate pre-culture of the chondral layer for 3 days prior to the generation of the composite allows for (i) more efficient cartilaginous matrix accumulation than no pre-culture, as assessed histologically and biochemically, and (ii) superior biological bonding to the bony scaffold than 14 days of pre-culture, as assessed using a peel-off mechanical test, developed to measure integration of bilayered materials. The presence of the bony scaffold induced an upregulation in the infiltrated cells of the osteoblast-related gene bone sialoprotein, indicative of the ...
Osteoarticular allografts represent a reconstructive option after bone tumor resection around the knee in growing children. The major advantage is the chance to preserve the growth plate of the remaining bone, but the disadvantage is the high failure rate eventually requiring definitive prosthetic replacement at skeletal maturity. We retrospectively reviewed 22 patients who underwent osteoarticular allograft reconstructions of the distal femur (16) or proximal tibia (6). There were 12 females and 10 males with an average age at surgery of 11 years (7-15). The diagnosis was osteosarcoma in 19 cases and Ewing sarcoma in 3. All patients underwent pre- and post-operative chemotherapy. At an average follow-up of 103 months (12-167), 18 patients (82%) were alive and 4 had died (18%). We observed 10 allograft failures requiring prosthetic replacement, 6 in distal femur and 4 in proximal tibia reconstructions. At last follow-up 8 allografts (36%) were still in place. Overall allograft survival was 79.6% ...

Authors: Lewandrowski, Kai‐Uwe , Bondre, Shrikar P. , Gresser, Joseph D. , Wise, Donald L. , Tomford, William W. , Trantolo, Debra J. Article Type: Research Article Abstract: Alteration of the geometrical surface configuration of cortical bone allografts may improve incorporation into host bone. A porous biodegradable coating that would maintain immediate structural recovery and subsequently allow normal graft healing and remodeling by promoting bony ingrowth could provide an osteoconductive surface scaffold. We investigated the feasibility of augmenting cortical bone grafts with osteoconductive biodegradable polymeric scaffold coatings. Three types of bone grafts were prepared: Type I - cortical bone without coating (control), Type II - cortical bone coated with PLGA‐foam, Type III - cortical bone coated with PPF‐foam. The grafts were implanted into the rat tibial metaphysis (16 …animals for each type of bone graft). Post‐operatively the animals were sacrificed at 2 weeks and 4 weeks ...

Massive bone allografts have been used for limb salvage of bone tumor resections as an alternative to endoprostheses, although they have different outcomes and risks. There is no general consensus about when to use these alternatives, but when it is possible to save the native joints after the resection of a long bone tumor, intercalary allografts offer some advantages despite complications, such as fracture. The management and outcomes of this complication deserve more study.. ...

Method The non-union was treated by freshening the fracture ends, opening the medullary canal, re-aligning and stabilizing the fracture with a plate and packing autogenous cancellous bone grafts around the non-union site. There were 25 patients with an average age of 35 years. The non-union involved 7 femurs, 8 humerii and 10 tibiae. The initial treatment was operative in 11 patients, by plaster cast in 5, by traction in 1 and by traditional practitioner in 8. There was no pathological fractures or infected cases. The average delay prior to operation was 14 months and the average follow up was 30 months ...
With all possible programs taken into account, Augment signifies an enormously profitable prospect for the biotech organization. In the United States, whole bone grafting methods are a $four billion once-a-year market. Increase could largely replace these with a superior merchandise and method. Existing costs of harvesting autogenous bone grafts range from $1100 to $2500 for every method. Of course, this does not take into account expenses relating to discomfort management at the donor site and the prospective for important difficulties. Considering that Increase eliminates the want for harvesting donor bone, these aspects are eliminated ...

Revision TKA with structural bulk allografting is associated with an up to 20% complication rate, usually related directly or indirectly to the allograft itself.10 For this reason endoprostheses are favoured by some authors.. Osteo-articular allografts. Historically in the 1970s there was a surge of interest in the use of bulk osteo-articular allografts. The benefit of osteo-articular grafting is joint preservation and soft tissue reattachment. However high complication rates were reported, particularly infection, fracture, non-union, graft dissolution and joint instability.11,12 Donor grafts need to be carefully matched to the recipient articular surface.The articular cartilage undergoes preservation in dimethyl sulfoxide and is stored at -80°C which results in very few of the chondrocytes remaining viable. This technique is seldom utilised today because of medium- and long-term failure. Hornicek et al reported that 25% of osteo-chondral allografts required surgical intervention due to ...

This is followed by instillation of 30mL of water-soluble contrast and a plain radiograph is obtained; leakage of the contrast suggests urethral injury (usually secondary to pelvic trauma) and is an indication for surgical intervention. It is used when there is suspicion of urethral trauma, such as a history of trauma to the area followed by pain, inability to void urine, or the presence of blood at the urethral meatus, a scrotal hematoma, or free-floating prostate on rectal examination. If a urethral injury is suspected, a retrograde urethrogram should be performed before attempting to place a Foley catheter into the bladder. If there is a urethral disruption, a suprapubic catheter should be placed. ...

  • A bone marrow donor is usually a close relative of the patient. (
  • Parallel studies of human bone marrow transplantation for malignancies by Mathe and colleagues focused on attempts to achieve GVT without fatal GVHD, but these were complicated by lack of sustainable engraftment of donor hematopoietic cells. (
  • Healthy bone marrow - from a donor whose tissue matches that of the patient, from the patient, or from umbilical cord blood - is then given via intravenous infusion. (
  • In the future, it can allow to abandon bone marrow transplantation and patients will no longer need to wait for suitable donor material. (
  • Bone marrow transplantation is uniquely curative for many patients with hematological malignancies due to the targeting of tumor cells by the transplanted donor immune system. (
  • We have developed several approaches for allogeneic transplantation with reduced intensity chemotherapy regimens in which anti-tumor effects are primarily mediated by donor immune cells. (
  • Paired donor exchange kidney transplantation is a process in which unrelated kidney donors are matched to recipients so that compatible transplants can be performed. (
  • Because only a small amount of bone marrow is removed, donating usually does not pose any significant problems for the donor. (
  • The area where the bone marrow was taken out may feel stiff or sore for a few days, and the donor may feel tired. (
  • After the successful bone marrow transplantation, the MHC molecules on cells derived from the donor bone marrow will match the haplotype expressed on the donor's kidney. (
  • The recipient had no known risk for HIV infection other than the bone grafting procedure, and the bone donor was subsequently found to have been infected with HIV. (
  • The bone donor was a 52-year-old man who had donated his left femoral head, which was excised during a hip arthroplasty procedure performed for degenerative joint disease in November 1984. (
  • We developed preclinical models of bone marrow transplantation (BMT) for MM using Vk*MYC myeloma-bearing recipient mice and donor mice that were myeloma naive or myeloma experienced to simulate autologous transplantation. (
  • While the center is best known for supplying blood products to hospitals, SBC's HLA lab supports the success of hundreds of bone marrow transplants administered at Stanford Health Care by providing and developing tests to determine donor and recipient organ compatibility. (
  • If bone marrow from a sibling is unavailable, the lab will search the National Marrow Donor Program registry for a match. (
  • Consider becoming a bone marrow donor and see if your HLA type could be a match for a sick patient. (
  • To find out how to become a donor or to learn more about bone marrow transplantation, visit Be the Match . (
  • Moreover, in our human cell therapy trials, donor osteoblast engraftment was demonstrated after transplantation of unmanipulated bone marrow ( 14 ), but the percentage of such engraftment could not be improved by transplanting as many as 5 × 10 6 isolated plastic-adherent marrow stromal cells per kg of body weight, a cell number that greatly exceeds the marrow stromal cell content of unmanipulated marrow ( 15 ). (
  • An image depicting bone marrow donor typing procedures can be seen below. (
  • Most bone marrow donor procedures are performed under general anesthesia. (
  • The grafting of bone from a donor site to a recipient site. (

  • If you are a candidate for bone marrow transplantation but do not have a matching donor, you may benefit from our experience performing this procedure using mismatched donors. (
  • Partial matches" have made bone marrow transplantation a possibility for people who may have a challenging time finding a matched donor, such as those from ethnic minority groups. (
  • A bone marrow transplant involves taking cells that are normally found in the bone marrow (stem cells), filtering those cells, and giving them back either to the donor (patient) or to another person. (
  • There are different types of bone marrow transplants depending on who the donor is. (
  • Stem cells are taken either by bone marrow harvest or apheresis from a genetically matched donor, usually a brother or sister. (
  • Unrelated bone marrow transplants (UBMT or MUD for matched unrelated donor). (
  • This leads to a state of mixed chimerism early after transplant where both recipient and donor HSC coexist in the bone marrow space. (
  • Allogeneic bone marrow transplantation involves two people, one is the (normal) donor and one is the (patient) recipient. (
  • In the case of a bone marrow transplant (BMT), the HSC are removed from a large bone of the donor, typically the pelvis, through a large needle that reaches the center of the bone. (
  • Our Mount Sinai bone marrow transplant specialists perform different types of BMT, and the right one depends on patient condition and availability of a compatible donor. (
  • Read about becoming a bone marrow donor . (
  • Bone marrow produces stem cells-unspecialized cells from the compatible donor-that renew by dividing into more cells that are specialized. (
  • We characterized the effect of transplanted donor mononuclear cells on relapse- and event-free survival after allogeneic bone marrow transplantation (BMT). (
  • In conclusion, content of donor DC2 cells was associated with decreased chronic graft-vs-host disease and graft-vs-leukemia effects consistent with Th2/Tc2 polarization of donor T cells following allogeneic bone marrow transplantation. (
  • The Allogeneic bone-marrow transplantation represents the only curative treatment and requires a compatible donor HLA. (
  • However, if this is not possible, for example, when a patient's blood marrow is not healthy, the bone marrow must come from a tissue-matched donor - this is called an allogenic transplant. (
  • In most allogenic transplants, the bone marrow is donated by a close relative, but sometimes the donor is an unrelated person who is a close genetic match to the patient. (
  • Matching donor and recipient tissue type is vital for the success of a bone marrow transplant. (
  • Normally, family members are the best source of compatible bone marrow tissue, but if a suitable donor is not found within the family , a suitable unrelated donor must be found. (
  • After a bone marrow transfusion, the recipient's blood group will change to that of the donor. (
  • The New Zealand Bone Marrow Donor Registry (NZBMDR) was formed in 1996. (
  • The NZBMDR is part of Bone Marrow Donors Worldwide - an organisation that helps patients around the world to find a compatible donor. (
  • By preventing the occurrence of GvHD, ATIR enables the use of a mismatched donor and consequently addresses a significant limitation in bone marrow transplantation , the timely availability of a donor. (
  • In this study the efficacy of ATIR(TM) will be investigated in patients diagnosed with AML, ALL or MDS eligible for an allogeneic bone marrow transplantation but for whom no matching donor is available. (
  • OBJECTIVES: I. Evaluate the incidence of acute graft versus host disease in patients undergoing transplantation with an unrelated or related matched or mismatched antigen donor. (

  • Allogeneic BMT can be categorized by whether the donor cells were harvested from the bone marrow or obtained by apheresis of peripheral blood. (
  • As more donor T cells are collected with peripheral blood than bone marrow, most studies have shown GVHD to be increased. (
  • Details how the factors that drove clinical use of high-dose chemotherapy with autologous bone marrow transplantation (HDC/ABMT)-patient demand, physician enthusiasm, media reporting, litigation, and administrative mandates-converged to propel the procedure forward despite a lack of proven clinical effectiveness.

  • Allogeneic transplantation is not indicated in first complete remission for patients with low cytogenetic risk, and it appears that allogeneic transplantation, autologous transplantation, and consolidation chemotherapy are equivalent for patients with intermediate risk. (
  • In a bone-marrow transplant, the patient is treated with very high doses of chemotherapy, with or without radiation, to destroy cancer cells. (
  • When the doses of chemotherapy or radiation needed to cure a cancer are so high that a person's bone marrow stem cells will be permanently damaged or destroyed by the treatment, a bone marrow transplant may be needed. (
  • Replace the bone marrow and restore its normal function after high doses of chemotherapy and/or radiation are given to treat a malignancy. (
  • Non-myeloablative allogeneic HSCT is a newer treatment approach which uses lower doses of chemotherapy and radiation which are too low to erradicate all of the bone marrow cells of a recipient. (
  • Before transplantation , the patient is given high doses of chemotherapy or radiation to destroy their own cancerous or abnormal blood cells. (

(
  • When Thomas came to Seattle in 1963, his team at the University of Washington sought to use radiation and chemotherapy to destroy a patient's diseased bone marrow and then replace it with new marrow from a healthy patient. (
  • In addition to complications seen from exposure to chemotherapy and radiation, patients undergoing allogeneic transplantation can experience unique late effects secondary to graft versus host disease (GVHD) and autoimmunity. (
  • Such diseases require serious complex treatment and surgery and transplantation of the destroyed bone marrow in severe stages. (
  • Every year individuals receive hematopoietic stem cell transplantation (HSCT) to eradicate malignant and nonmalignant disease. (

  • Bone disease post-transplantation is a major cause of morbidity in kidney transplant recipients, with a significantly higher risk of fractures as well as increased health care costs, hospitalization, and mortality ( 1 ). (
  • Post-transplantation bone disease is characterized by changes in bone quality and density as well as mineral metabolism, which contribute to increased fracture risk, and therefore, post-transplantation bone disease is significantly different from the range of chronic kidney disease and mineral bone disorders (CKD-MBDs) seen pretransplantation. (
  • This risk remains significantly elevated even 10 years post-transplantation, suggesting that bone remains fragile after transplantation, despite improvement in parameters of mineral metabolism ( 1 ). (

  • Harvested bone marrow can be combined with a preservative and frozen to keep the stem cells alive until they are needed. (
  • It also can occur if not enough stem cells are used, the new stem cells are damaged during storage, or your bone marrow is damaged after the transplant. (
  • Hematopoietic Reconstitution by Transplantation of Stem Cells from Bone Marrow or Blood. (
  • Bone marrow is in the center of the bone and contains hematopoietic stem cells (HSC). (
  • When bone marrow is damaged or destroyed, it can no longer make normal blood cells and a stem cell transplant (bone marrow transplant) is required. (
  • A bone marrow transplant is the process of replacing unhealthy HSC with healthy ones in order to restart hematopoiesis, the process of generating red blood cells, white blood cells, and platelets. (
  • Bone marrow cells contribute to many diverse tissues after systemic transplantation in both mice and humans ( 1 , 2 ). (
  • This capacity may solely reflect the activities of multiple discrete stem cells with restricted genetic programs, such as hematopoietic stem cells able to differentiate to leukocytes, erythrocytes, or megakaryocytes and mesenchymal stem cells that can differentiate to bone, cartilage, or adipose tissue ( 3 ). (
  • Alternatively, the bone marrow may contain rare "marrow stem cells" with the potential to differentiate to a spectrum of tissues, possibly in response to specific environmental cues. (
  • Consistent with this idea is the observation, reported over a decade ago, that nonadherent CD34 bone marrow cells can differentiate to osteoblasts ( 12 ) and the quite recent report that murine bone marrow side population (SP) cells can engraft in bone after transplantation ( 13 ). (
  • One interpretation of these observations is that cells other than those in the adherent population, where mesenchymal stem cells are thought to reside ( 3 ), are potent transplantable progenitors of osteoblasts, consistent with laboratory studies showing that nonadherent cells can give rise to bone ( 12 , 13 , 16 ). (
  • We tested this prediction in a murine transplantation model by using gene-marked bone marrow cells and retroviral integration site-specific PCR analysis. (
  • Transduction and Transplantation of Marrow Cells. (
  • Bone marrow was flushed from the dissected femurs and tibias of FVB/N mice (The Jackson Laboratory), and the isolated adherent marrow cells were transduced with a GFP-expressing retroviral vector (multiplicity of infection, ≈5) as described ( 17 ). (
  • The goal of BMT is to transfuse healthy bone marrow cells into a person after his or her own unhealthy bone marrow has been treated to kill the abnormal cells. (
  • It is the stem cells that are needed in bone marrow transplant. (
  • Stem cells are taken from the patient either by bone marrow harvest or apheresis (a process of collecting peripheral blood stem cells), frozen, and then given back to the patient after intensive treatment. (
  • These stem cells reproduce into mature, functioning blood cells quicker and more effectively than do stem cells taken from the bone marrow of another child or adult. (

  • 10-15] Transplantation with fewer than 1 × 10 6 CD34-positive cells/kg from T-cell-depleted allogeneic bone marrow and peripheral blood stem cell grafts was associated with increased relapse and treatment-related mortality. (
  • Hematopoietic stem cells (HSCs) are very rare cells, representing approximately one in 100,000 bone marrow (BM) cells in the adult. (
  • Did you know that bone marrow contains adult stem cells? (
  • Bone marrow is a soft, sponge-like tissue in the centre of bones where blood cells are made. (
  • Blood stem cells, which are also known as haematopoietic stem cells, can differentiate into all blood cell types, including white blood cells, red blood cells, and platelets, whereas stromal stem cells can differentiate into fat, cartilage , and bone cells. (
  • If the HLAs don't match, the donated bone marrow stem cells may attack the recipient's tissue. (
  • This substance increases the number of bone marrow stem cells circulating in the blood. (
  • Once on the registry, only one person out of every 1,000 is ever asked to donate bone marrow stem cells. (
  • Similar procedures in humans, though more difficult, might prove helpful in isolating human stem cells and could improve the efficiency and safety of bone marrow transplantation , they add. (

  • For transplantation, we embedded the iPS cells within the collagen hydrogel in order to obtain the effective administration of the cells into defects, which induced the differentiation of the iPS cells. (
  • At 8 weeks of transplantation, although the iPS cells with a 75% homology to the host in the genetic background tended to form teratoma, those of 100% showed a joint regeneration. (
  • EPC transplantation significantly reduced brain edema and the number of dead cells in the hematoma boundary areas. (
  • An infection of a bone is called osteomyelitis. (
  • The significant determinants of change in BMD were age (LS), change in osteocalcin levels (TF) and CMV infection (TB), explaining about 9 %, 18 % and 10 % of the bone loss, respectively. (
  • Infection is the major problem with allogeneic bone marrow transplantation. (
  • The patient undergoing allogeneic bone marrow transplantation is at particularly high risk of infection due to the major perturbations of host defenses, which include granulo- cytopenia, cellular immune dysfunction, humoral immune dysfunction, blood product transfusions, and vascular access devices.
