Résumé :

Trial Design. This analysis compared the outcome of fresh-frozen versus autologous bone block grafts for horizontal ridge augmentation in patients with Cawood and Howell class IV atrophies.Methods. Seventeen patients received autologous grafts and 21 patients received fresh-frozen bone grafts. Patients underwent CT scans 1 week and 6 months after surgery for graft volume and density analysis.Results. Two autologous and 3 fresh-frozen grafts failed. Autologous and fresh-frozen grafts lost, respectively, 28% and 46% of their initial volume(P=0.028). It is noteworthy that less dense fresh-frozen blocks lost more volume than denser grafts (61% versus 16%).Conclusions. According to these 6-month results, only denser fresh-frozen bone graft may be an acceptable alternative to autologous bone for horizontal ridge augmentation. Further studies are needed to investigate its behaviour at longer time points.

Résumé :

In implant dentistry, there is continuing debate regarding whether a barrier membrane should be applied to cover autologous bone grafts in jaw augmentation. A membrane would prevent graft remodeling with resorption and enhance graft incorporation. We hypothesized that membrane coverage does not effect resorption and incorporation of autologous onlay bone grafts. We treated 192 male Sprague-Dawley rats. A 4.0-mm-diameter bone graft was harvested from the right mandibular angle and transplanted to the left. Poly(DL-lactide-ε-caprolactone), collagen, and expanded polytetrafluoroethylene membranes were used to cover the grafts. The controls were left uncovered. Graft resorption at 2, 4, and 12 weeks was evaluated by post mortem microradiography and microCT. Analysis of the data showed no significant differences among the 4 groups. This demonstrates that the indication of barrier membrane use, to prevent bone remodeling with resorption and to enhance incorporation of autologous onlay bone grafts, is at least disputable.

Résumé :

AbstractA large variety of graft materials have been used for augmentation rhinoplasty. To date there has been no graft material which can be regarded as completely satisfactory. The modern trend is to prefer autologous material to new biological material. The membranous bones of the calvarium are extremely suitable for augmenting moderate to severe saddle nose deformities. Calvarial bone grafts can be harvested easily, with minimum donor site morbidity and disfigurement. Our experience with calvarial bone grafts for augmentation rhinoplasty is presented.

Résumé :

BACKGROUND In the management of bony defects, autologous bone grafts can be used as the mechanical structure for reconstruction to restore aesthetics and function, Non-vascularized autologus fibular graft are often used to the treat large post traumatic defects caused by high-energy trauma with open fracture and nonunion cases for 1st and 2nd cases. Here we would like to present a 16-year-old woman and a 37-year-old man patients of major bone defect at the right femoral shaft region using 9 cm and 10 cm non-vascularized fibular autogenous grafts. OBJECTIVE The purpose of this case report was to determine the effectiveness of non-vascularized autologus fibular graft for major bone defect at the regio femoral shaft for the reconstruction of post traumatic case. MATERIAL AND METHODS We treat post traumatic of the major bone defect at the regio femoral shaft with 9 cm and 10 cm femoral non-vascularized autologus fibular graft and fixed by a limited contact dynamic compression plate and femoral locking plate methode by routine phisioteraphy. RESULTS The Patient have a good result with good functional outcome after open reduction internal fixation (ORIF) and using a non-vascularized autologus fibular graft for treating the major bone defect after post traumatic femoral shaft fracture. CONCLUSION Complete and comperhensive open reduction internal fixation (ORIF) with autologous non- vascularized fibular graft, stabilized fracture by limited contact dynamic compression plate for 1st patient and femoral locking plate for 2nd patient allowing with an early rehabilitation is an acceptable, Phisioteraphy and early mobilisation resulting better outcome for the patient, all of this are less expensive, can be accepted at the hospitals that limited facilities and health professionals for professional subspeciality and widely reproducible option to manage bone defects in open shaft femoral fractures to achieving union, preserving length and motion with no donor site morbidity, giving patients good functional outcome and radiologic result. KEYWORDS Major bone defect, non-vascularized autologus fibular graft, autologous bone grafts, femoral shaft fracture, Open Fracture, Muskuloskeletal Reconstruction, Bone Loss, Nonunion.

Résumé :

Abstract Autologous bone marrow transplants (BMTs) can repopulate the hematologic system of patients treated with marrow-ablative chemotherapy and/or radiotherapy. However, treatment of the bone marrow graft to eliminate residual tumor cells prior to reinfusion can delay the return of peripheral blood elements, presumably from damage to or loss of hematopoietic stem cells responsible for hematologic recovery. To develop a model predictive of hematologic recovery, we studied the progenitor cell contents of 4-hydroperoxycyclophosphamide (100 micrograms/mL)-purged bone marrow grafts of 40 consecutive patients undergoing autologous BMT at this center. Granulocyte-macrophage colonies (CFU-GM) were grown from all grafts after treatment with this chemotherapeutic agent, but erythroid (BFU-E) and mixed (CFU-GEMM) colonies were grown from only 44% and 33% of the grafts respectively. The recovery of CFU-GM after purging ranged from 0.07% to 23%. The logarithm of CFU-GM content of the treated grafts was linearly correlated with the time to recovery of peripheral blood leukocytes (r = -0.80), neutrophils (r = -0.79), reticulocytes (r = -0.60), and platelets (r = -0.66). The CFU-GM content of purged autologous bone marrow grafts may reflect the hematopoietic stem cell content of the grafts and thus predict the rate of hematologic recovery in patients undergoing autologous BMT.

Résumé :

Objective: To compare the outcomes of 2 different bone graft materials: autogenous bone grafts from mandibular symphysis and bovine bone grafts associated with platelet-rich plasma (PRP). Methods: Twenty individuals met the inclusion criteria and accepted to participate in the study. Group A patients underwent alveolar bone grafting using autologous bone and group B patients using a bovine bone graft associated with PRP. Cone beam computed tomography scans were taken and reconstructed 3-dimensionally for all patients preoperatively and 1 year postoperatively. Results: A significant reduction was detected for area and volume within group A and group B. Between groups, no significant difference was found for area or volume. Conclusions: Bovine grafts associated with PRP are a good option for the reconstruction of alveolar clefts and provide good results such as autologous bone grafts.

Résumé :

The use of implants in pediatric cranioplasty is still debatable. Many surgeons prefer to use autologous bone grafts than implants due to previous concerns that implants have a higher risk of infection, allergic response, and are not biocompatible as an autologous bone graft. However, recent studies showed that several implant materials have a similar infection rate following cranioplasty or might be lower compared to autologous bone. Moreover, several studies also reported a high rate of bone flap resorption in autograft cranioplasty, particularly in patients below the age of 8 years, thus requiring revision surgery with an implant as a substitute in most cases. Implant materials also have advantages in several conditions that make them more suitable than autologous bone grafts. This literature review is expected to give information about the type of implant materials that can be used as an alternative to substitute autologous bone grafts in certain conditions.

Résumé :

✓ Autologous bone grafts are currently considered “gold standard” material for achieving long-term spinal arthrodesis. The present study was performed to determine whether demineralized bone matrix (DBM), type I collagen gels, or bone morphogenetic protein-2 (BMP-2) can improve autologous bone spinal fusions. Using a unilateral decompression—contralateral fusion technique in dogs, each of these materials was added to an autologous bone graft. Volumetric analysis, histological analysis, and biomechanical testing were performed to assess the effectiveness of each material. The DBM had an inhibitory effect on solid bone fusion of the spine, whereas the type I collagen gels improved the bony interface between the graft and the host spine. The BMP-2 strongly enhanced the amount of bone deposition at the fusion site and increased the number of intervertebral levels that were solidly fused. This study strongly supports the use of BMP-2 as an additive to autologous bone grafts in spine stabilization.

Résumé :

Most of edentulous areas need reconstructive procedures of hard tissues for an ideal implant position. In this perspective, guided bone regeneration with semi-permeable membranes or onlay bone grafts harvested from intra-or extra-oral sites is indicated. Establishment of well regulated tissue banks allows surgeons use of allograft bone. This study compares two clinical cases, where a relevant horizontal deficit was present: first one reconstructed with allograft bone + titanium mesh and the other one with onlay graft + autogenous cortico-spongiosa bone particles, harvested from ramus. In both cases plasma rich in growth factors and fibrin membranes were used in order to enhance graft vascularization and osseous regeneration, as well as faster healing.

Résumé :

SURGICAL-RADIOGRAPHIC PART:The aim of the present retrospective chart review was to determine the relationship between nonvascularized osseous graft remodeling and the three-dimensional (3D) features of grafts and recipient sites, the anatomical recipient regions and different graft procedures. 18 iliac crest were onlay-positioned in the mandible or maxilla or used in sinus lift procedures. CT scans, taken before implant positioning and after 1 year, revealed a mean volume resorption of 40%. For iliac crest grafts, the average resorption was 36% when the onlay was positioned in the anterior maxilla, 77% when it was positioned in the posterior mandible and 17% in sinus lift procedures. GENIC PART: This part of the study aims to identify and rank genes involved in osseous augmentation or bone remodeling to obtain groups with more numerous predicted associations called the leader gene clusters. An iterative search (consisting of a consecutive expansion-filtering loop) was performed for which only genes involved in a specific process were identified. For each gene, predicted associations with all other involved genes were obtained from a Web-available database (Search Tool for the Retrieval of Interacting Genes/Proteins) and the weighted number of links (WNL), given by the sum of only high-confidence predicted associations (results with a score > or =0.9), allowing gene ranking. A total of 161 genes potentially involved in bone-volume augmentation and 128 genes connected with the bone-remodeling phenomenon were identified.

Résumé :

Aim: The aim of this literature study was to systematically review the scientific evidence on the most effective donor sites and/or bone substitute material for secondary alveolar cleft grafting in alveolar cleft patients. Material and method: In order to acquire a systematic and transparent reporting this literature review was conducted according to the PRISMA statement. The literature search was performed in the following four databases; PubMed, CENTRAL, Web of Science and Scopus.The quality of the included studies was assessed using the revised Cochrane Risk of Bias 2 tool (RoB 2 tool). Result: The search identified 4754 studies. Five RCT studies was included in this systematic review and assessed different donor site or bone substitute materials. Two studies showed low risk of bias and three moderate risk of bias. Only one study showed a statistically significant difference when comparing iliac bone to substitute material however all studies presented substitute materials with satisfactory results. Conclusion: According to the data from this systematic review no clear conclusion can be drawn regarding what the most effective bone donor site and/or tissue engineered bone substitute material to use in secondary bone grafts. Based on the available evidence iliac bone could still be regarded as a benchmark, but more research and RCT’s of high quality are required, especially for artificial bone substitute materials.

Les pertes de substance osseuse, résultant d'accidents ou de résection thérapeutique, doivent être comblées par un matériau qui offre à la fois des conditions de comblement et de cicatrisation satisfaisantes, associées à des qualités mécaniques optimales. Après une présentation sur la structure de l'os et sa cicatrisation, sont décrites les différentes solutions techniques pour le traitement des pertes de substance osseuse avec leurs avantages et leurs limites propres. La deuxième partie est une étude expérimentale concernant l'élaboration d'un matériau de comblement osseux autologue chez le mouton. De la moelle osseuse est prélevée sur la brebis, elle est mise en culture afin d'augmenter le nombre de cellules souches à capacité ostéogénique. A partir du sang prélevé sur la même brebis, une colle biologique est obtenue. L'association de ces deux produits constitue un greffon qui, disposé dans une perte de substance osseuse créée par forage au niveau de l'épiphyse distale du fémur de la même brebis de départ, est capable d'initier la formation de l'os. Dans le traitement de pertes de substance osseuse, la greffe autologue de cellules souches mésenchymateuses sur un support de gel de plaquettes constitue un substitut biologique intéressant de la greffe osseuse
Bone defects, due to injuries or therapeutic resections, should be treated with a material gathering filling defects conditions and optimum mechanical qualities. In a first part, bone structure and bone healing mechanisms are presented. A review of the available techniques to treat bone defects is then reported. In a second part, an experimental study is carried on about a new autologous material made from sheep. Bone marrow from one sheep is cultured in order to increase the number of osteoprogenitor stem cells. A platelet gel is made from the sheep blood after centrifugation and cryoprecipitation. The association of these two products leads to an autologous graft transplant able to make new bone in bone defects created by drilling in distal femoral epiphysis. The association of mesenchymal stem cells with a platelet gel seems to be an interesting bone graft substitute

Résumé :

Scoliosis is an anatomical deformity caused by a lateral and rotational shift in the thoracolumbar spine. Surgical correction involves wide exposure of the spine for placement of stabilizing rods and can result in significant complications from excessive blood loss and neurologic impairments. These procedures require vigilance to acid-base status, hemodynamic fluctuations, coagulation, temperature maintenance, and neurologic monitoring from anesthesiologists. Other major anesthetic considerations discussed include maintaining the integrity of perfusion to the spinal cord, positioning concerns, optimal technique for neuromonitoring, and pain control in the perioperative period. This chapter presents a case study of a 14-year-old girl with adolescent idiopathic scoliosis who presents for posterior spinal instrumentation and fusion from T4-L4 with autologous bone graft.

Résumé :

Bone marrow transplants are an exciting and rapidly evolving area of haematology providing life-saving therapy to many patients and the number performed annually is increasing. Transplants are generally not considered as first line therapy due to their inherent toxicity and high rate of complications. The patients tend to have more heavily pre-treated disease with it attendant toxicities and a decreased physiological reserve. Admission rates vary between series from 15 to 30%. It is increasingly important that intensivists are aware of the basic principles of bone marrow transplantation and its’ possible morbidities. There are two types of transplant autologous transplants, where the patient’s own stem cells are returned to them and transplants from a donor. Only allogeneic transplants are associated with graft-versus-host disease. Allograft recipients also require immunosuppression to prevent transplant rejection. It is essential that this immunosuppression is continued when patients are admitted to intensive care. Transplant patients are always severely immunocompromised and prone to prolonged periods of neutropenia. They routinely receive antiviral, antifungal, and antibacterial prophylaxis, which must be continued on their admission. They remain vulnerable to unusual infections presenting in an atypical fashion. It is essential to have both a very low clinical threshold of suspicion for infection and detailed local protocols established to guide empirical antimicrobial therapy. Although traditionally poor, the prognosis is slowly improving.

Résumé :

Cartilage plays an important role in reducing mechanical stress and assist with smooth limb movement. Osteoarthritis is the degeneration of articular cartilage and bone. This osteochondral region is difficult to heal because of its dissimilar healing capability, so osteochondral transplantation is the most common method to resolve this issue. Post-traumatic osteoarthritis develops after a joint injury and can damage the cartilage and accelerate its wear and tear. Mosaicplasty is the most widely used method involving transplantation of small cylindrical bone cartilage plugs to fill up the affected region. The success of harvesting a larger and complex shaped graft to replace the damaged osteochondral area lies in effective extraction of the cartilage-bone graft from the donor site. Currently, no method exists to perform this procedure for autologous transplantation due to the complexity involved to extract graft without damaging the donor site. In this paper, we propose a novel graft removal mechanism to harvest a personalized autologous graft of virtually any shape and size. Our method involves drilling a profile similar to the effected region on the donor site and slicing off the desired cartilage-bone graft from its root to harvest it. We developed a new graft removal mechanism capable of inserting a flexible saw parallel to the transverse plane and slice the graft parallel to the coronal plane to extract a donor graft for autografting procedures.

Résumé :

The primary goal of tissue engineering is to develop a biological, mechanically-robust, and anti-thrombogenic vascular graft to replace diseased or damaged tissue and organs [1]. For example, researchers have incorporated smooth muscle cells (SMCs) into extracellular matrix to provide a living, functional conduits with the intended purpose of replacing SMC-containing tubes, such as the blood vessel, urethra, esophagus, intestine, etc. Although the preferred source is autologous cells to avoid immunological rejection, adult SMCs are difficult to obtain and expand. An alternative source of autologous cells could be bone marrow derived stem cells (BMSCs), which differentiate toward mesenchymal and hematopoietic lineages [2].
