Histological features of large bone allografts.
We performed biopsies during reoperation for minor complications in two active young patients 9 and 19 months after massive bone allograft implantation for bone tumour. The grafts were dead and resorption-apposition activity, when present, was predominantly in subperiosteal areas. Inflammatory infiltration was very seldom found. Features considered as 'microfractures' or 'microcracks' were note...
متن کاملPeculiar Immunobiology of Bone Marrow Allografts
Mice are capable of rejecting H-2-incompatible bone marrow grafts after a single lethal exposure to X-rays. The onset of rejection begins 18-24 hr after transplantation and is completed by 96 hr. Maturation of this type of allograft reactivity does not occur until the 22nd day of life. In adult mice, the resistance to marrow allografts can be weakened by administration of cyclophosphamide or de...
متن کاملMaxillary ridge augmentation with fresh-frozen bone allografts.
PURPOSE The present investigation clinically and histologically evaluated the use of fresh-frozen bone in the reconstruction of maxillary alveolar ridges to confirm the effective bone fill and support for the placement of dental implants. PATIENTS AND METHODS Fifteen patients who had atrophic maxillary ridge necessitating bone block grafts prior to implant placement were submitted to maxillar...
متن کاملAntimicrobial implants and bone allografts: new uses for old antibiotics
Bone grafting is the procedure whereby missing bone is replaced with material from either the patient’s own body (autograft), that of a donor (allograft) or with synthetics. The use of exogenous materials to reconstruct skeletal defects is not a new concept. Artificial, synthetic or natural substitutes, in the form of gold and silver plates and pieces of coconut shell, were found in cranial def...
متن کاملModerate heat treatment of bone allografts. Experimental results of osteointegration.
The use of bone allografts is often essential in orthopedic surgery. Strict donor screening, including HIV testing 3 months postoperatively, is mandatory before a transplant may be used. Yet these measures do not definitely rule out the possibility of HIV transmission, as there is a window period before infection is revealed by blood testing. Accordingly, there is a need for virus inactivation ...
