Massive allograft can be a useful option in revision total joint arthroplasty for treatment of significant bone loss. In rare cases, revision hip and knee arthroplasty procedures can be performed simultaneously using massive allograft-prosthetic composites. We present an 18 year follow up of a patient who received a simultaneous revision hip and knee total femoral allograft and discuss recent l...

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...

PURPOSE The purpose of this study was to analyze the clinical outcome of arthroscopic anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone autograft versus allograft. METHODS Between May 2000 and June 2004, 172 patients undergoing arthroscopic bone-patellar tendon-bone ACL reconstruction were prospectively randomized into autograft (n = 86) or allograft (n = 86) grou...

BACKGROUND Hamstring (HS) autograft and bone-patellar tendon-bone allograft are the most common choice for reconstruction of anterior cruciate ligament (ACL). There was a little report about the clinical outcome and difference of arthroscopic ACL reconstruction using allograft and autograft. This study aimed to compare the clinical outcome of autograft and allograft reconstruction for ACL tears...

The potential shortage of allograft bone has led to the need to investigate other sources of bone for allografts. Some allograft bone donated from primary total hip arthroplasty recipients must be discarded or treated to become usable as a result of bacterial contamination. Femoral head allografts were contaminated with Staphylococcus aureus and Bacillus subtilis. A domestic microwave oven was ...

Introduction: Alveolar bone is the most affected of periodontal diseases. Bone grafts such as autograft, allograft, xenograft and, alloplastic often are used, but they have limitations. So, graft still a major problem that continues to inspire design new materials. The purpose this article review clinical and biologic function, advantages, disadvantages dentin an autograft allograft in therapy....

BACKGROUND The feasibility of distal femur epiphysis preservation through epiphyseal distraction by external fixator in childhood osteosarcoma was explored. METHODS Between July 2007 and May 2011, 10 children who were suffering from distal femur osteosarcoma received epiphyseal distraction by external fixator, combined with tumor resection and repair with massive allograft bone to preserve th...

This study was designed to evaluate the use of computer-assisted navigation with computed tomography (CT) images for bone reconstruction after resection in malignant bone tumor treatment. Forty-five patients with malignant bone tumors were recruited for this study. CT scan images in a computer-assisted navigation system were used to assist during the osteotomy, the pairing with allografts, and ...

Bone allografts can be used in any kind of surgery involving bone from minor defects to major bone loss after tumour resection. This review describes the various types of bone grafts and the current knowledge on bone allografts, from procurement and preparation to implantation. The surgical conditions for optimising the incorporation of bone are outlined, and surgeon expectations from a bone al...

The use of allograft bone is becoming increasingly common. intrinsic mechanical and structural properties the graft are major importance for osseointegration. Current cleaning treatments using chemical or physical products increase biosafety but may disturb these characteristics. A new treatment cancellous cortical by simple washing (sonication centrifugation) supercritical carbon dioxide (scCO...
