Abstract Objects:Giant cell tumor of bone (GCTB) isa locally aggressive lesion with unpredictable behavior. Here, we aim to evaluate the epidemiological characteristics, clinical and functional outcome of GCTB in a relatively large series of patients. Methods:Patients with the diagnosis of GCTB were included in this retrospective study.Surgical options included extended curettage wh...

We studied, ten patients (11 elbows) who had undergone 14 allograft-prosthesis composite reconstructions following failure of a previous total elbow replacement with massive structural bone loss. There were nine women and one man with a mean age of 64 years (40 to 84), who were reviewed at a mean of 75 months (24 to 213). One patient developed a deep infection after 26 months and had the allogr...

Deficiencies of acetabular bone stock at revision hip replacement were reconstructed with two different types of allograft using impaction bone grafting and a Burch-Schneider reinforcement ring. We compared a standard frozen non-irradiated bone bank allograft (group A) with a freeze-dried irradiated bone allograft, vitalised with autologous marrow (group B). We studied 78 patients (79 hips), of...

INTRODUCTION Structurally intact cancellous bone allograft is an attractive tissue form in that it may be filled with osteoinductive agents while providing immediate structural support. Bone allograft tissue is commonly submitted to gamma radiation sterilization of 25-35 kGy to prevent disease transmission from donor to host. In cortical bone, gamma radiation sterilization has been shown to cau...

Background: Correlations between bone marrow, heart, kidney, liver, skin and lung transplant rejection or survival with human cytokine gene polymorphisms have been described. There are also reports about the role of cytokines and Tumor Necrosis Factors-Alpha (TNF-α) on corneal transplant in animal models. Further studies are needed to clarify the role of cytokines in corneal allograft rejection...

The aim of the present case report was to demonstrate vertical gain in posterior resorbed mandible utilizing use an Allograft Customized Bone Block. presents a 66-year-old healthy female nonsmoker who lost her right mandibular molars long time ago. In past, she had implant placement, which failed due fracture implant. Due high risk nerve damage, left jaw and completely covered with bone. Since ...

Bone defects in revision hip surgery can be reconstructed with impacted morselized bone grafts. Rinsing these trabecular allografts may enhance graft incorporation by washing out immunogenic factors present in blood, marrow, and fat. However, it has been proposed that impaction of the graft releases biologically active factors, which can provide sufficient activity to stimulate new bone formati...
