background: anti-hla-antibodies are known to affect the allograft survival in transplant recipient patients. objective: the aim of this study was to evaluate the association between anti-hla antibodies and kidney allograft outcomes, particularly in recipients with concur-rent donor bone marrow cell infusion (dbmi). methods: between june 2006 and may 2007, forty living unrelated donor kidney tra...

background: perioglasâ (pg) is an alloplastic material used for grafting periodontal osseous defects since 1995. in animal models, it has been proven that pg achieves histologically good repair of surgically created defects. in clinical trials, pg was effective as an adjunct to conventional surgery in the treatment of intrabony defects. because the molecular events due to pg that are able to al...

the gamma irradiation has been used for end sterilization of allograft bones and its effects with a 25 kgy dosage on the osteoinductive properties of demineralized bone allograft powder was studied. this work carried out using an experimental method in an animal model. in this study the demineralized bone allograft powder which had been sterilized and prepared with gamma irradiation in a 25 kgy...

background: massive bone allograft is an option in cases of limb preservation and reconstruction after massive benign and malignant bone tumor resection. the purpose of this study was to analyze the outcome of these procedures at imam reza hospital, mashhad university of medical sciences. methods: in this study, 113 cases have been presented. eleven cases were excluded (patients has a traumatic...

Background: Limb salvaging surgeries are current surgical treatment of extremity bone sarcomas. Resected bonereplacement consists of two main methods; tumor prosthesis versus structural allograft. Biological reconstruction withan allograft is an economic cheap method in young sarcoma patients, however, the surgeons are more convinced withtumor prosthesis replacement.Methods: We evaluated the sh...

  This is the early results of 20 cases of massive osteoarticular allograft performed for reconstruction of lower limb s after resection of bone tumors. These cases include 7 distal femur and hemiarticular ,6 proximal tibio and hemiarticular, 3 total knee joints and 4 proximal femur with total hip replacement. Bone allografts were taken at steril condition from early postmortum cadavers and st...

This study was designed to compare bone mineral density, periosteal callus production, new bone formation, bone porosity, histologic appearance, and union of mid-diaphyseal segmental allografts of the femur stabilized with an interlocking nail technique in a canine model 6 months after the procedure. An in vivo study was performed to compare the effects of augmenting interlocking nail fixation ...

Abstract Introduction: Fractures in osteoporotic bones present a surgical challenge for fixation and are often associated with significant morbidity. Case presentation: We case of failed internal fracture femoral shaft 74-year-old patient osteoporosis. Fracture was undertaken using an extra medullary locking plate intramedullary cortical strut graft, hybrid technique, Locking Plate Allograft Co...
