  Allograft bone graft substitutes for spine fusion surgery
These factors are the major determinants of the usefulness of allograft (cadaver bone obtained from a tissue bank) as a replacement for autograft (the patient’s own bone) in spine fusion surgeries.
Allograft bone is an effective bone graft substitute in the pediatric population for scoliosis surgery, but is only useful as a bone graft supplement posteriorly in the adult patient.
In the thoracic spine, structural allograft is frequently used anteriorly.

Allograft: The transplant of an organ or tissue from one individual to another of the same species with a different genotype.
A transplant from one person to another, but not an identical twin, is an allograft.

 MedlinePlus Medical Encyclopedia: Meniscal allograft transplantation
Meniscal allograft transplantation is a type of surgery in which a new meniscus, a cartilage ring in the knee, is placed into your knee.
The new meniscus is tissue taken from a cadaver (allograft).
The allograft is tested in the lab for possible diseases.

 AllRefer Health - Bone Graft (Allograft, Autograft) - Surgery & Procedures
A bone graft is surgery to place new bone into spaces between or around broken bone (fractures) or holes (defects) in bone.
New bone to be grafted around fractures or defects can be taken from the patient's own healthy bone (autograft) or from frozen, donated bone (allograft).
An incision is made over the bone defect and the bone graft is shaped and inserted into and around the defect.

 Kinamed - Allograft Tissues
A host immune response, as often seen with fresh frozen bone, may result in fibrous encapsulation of the allograft and failure of the grafting procedure.
This critical step is performed to maximize the safety, not only for the pathogens screened for in the rare instance of a false negative test result, but for all other possible viral and bacterial pathogens.
With the constant discovery of new pathogens and the implication of known pathogens as causitive agents in many forms of chronic disease and cancer, this step insures maximum safety for the allograft recipient.

  Foot and Ankle Conditions: Ankle Allograft Replacement
Perhaps the specific problem of the allograft replacement is that the bone and cartilage which is transplanted does not heal, and further arthritis develops.
In an ankle allograft replacement, an entirely new joint surface (made of bone and cartilage from a fresh cadaver) is implanted instead of replacing the ankle joint with a replacement made of metal and plastic.
In a total ankle allograft replacement, an entirely new joint surface (made of bone and cartilage from a fresh cadaver) is implanted instead of replacing the ankle joint with a replacement made of metal and plastic.

  CBER - Human Bone Allograft: Manipulation and Homologous Use in Spine and Other Orthopedic Reconstruction and Repair
Grogen, in 1999, showed the use of allograft bone in scoliosis surgery and demonstrated this bone among 87 adolescent patients to be safe, reliable, an effective option, and found comparable results and clinical outcomes when compared to autograft bone.
So, to begin to try to differentiate between allograft and autograft, as it is used particularly in the lumbar spine for either structural support or a lattice for bone to grow through, I think is an artificial definition, and the one that we probably need to try to get away from a little bit.
First of all, for age, does the age of the donor affect the allograft, and there is a wide range of age that is accepted, and are there any thoughts taken into account in terms of the age range, in terms of the patients that are selected.

 2005 Annual Meeting Information - AAOS   (Site not responding. Last check: )
Although clinical studies indicate long-term success, outcome is adversely affected by excessive allograft resorption mediated by osteoclasts that often leads to host-allograft nonunion and allograft fracture.
Allograft bone was harvested from rodent femur and implanted into a recipient rodent intercalary femoral defect after treatment with either topical saline (control) or zoledronate (study).
To evaluate allograft incorporation and bone resorption plain radiographs and bone density measurements were obtained.

 Allograft Dermal Matrix Grafts (Alloderm®) for Penis Widening, Glanular Enhancement and Penile Widening Surgery by ...
During the processing of Allograft Dermal Matrix Grafts (Alloderm®), the cellular components that would be necessary for viral transmission and survival are removed.
When an Allograft dermal matrix graft is implanted into a patient, the patient's cells repopulate the graft, blood vessels grow into the graft, and the graft becomes part of the patients own tissue.
The advantages of Allograft Dermal Matrix Grafts (Alloderm®) over autograft dermal fat or autograft dermal grafts for penile girth enhancement are: it eliminates the need for incisions and scars at the donor sites "because there are none", and resulting pain and possible infection; and it significantly reduces the length of surgery.

 Allograft Implant Information from Our Lawyers in Knoxville, Tennessee
However, none of the tissue processing or allograft distribution companies involved has offered any explanation as to how their internal testing and controls could have allowed such illegal bone and tissue to be sold for transplantation into patients.
Not only are the recipients of a potentially contaminated allograft implant at risk for infection, but healthcare workers and tissue handlers who are in contact with the allograft are also faced with the threat of contracting disease.
Allograft implants are often utilized for a wide variety of reconstructive surgeries that require extra bone, skin, cartilage, tendons and connective tissue to complete, such as:

A method of loading tubular segments of allograft bone was used in theatre prior to implantation.This bone was held vertically in an antibiotic bath with a cylindrical outer electrode and a wire electrode down the centre of the bone.
Indications for allograft insertion were limb salvage for tumour (16), poor bone stock associated with infection (12), periprosthetic fracture (7), aseptic loosening (1) and recurrent dislocation of total hip replacement (1).
One allograft was revised with allograft exchange and vascularised fibular graft following fracture of metal fixation.There was one case of persistent non-union in a knee fusion which was treated after 21 months by removal of the intramedullary fixation and allograft and use of an Ilizarov frame.

Improvements demonstrated in the short-term cannot be isolated to meniscal allograft transplantation as concomitant procedures are often performed.

 Late Renal Allograft Dysfunction: Home
Although renal allograft and recipient survivals have also increased during the last decade, over the last several years one-year graft survival and allograft half-life are largely unchanged.
In view of the apparent trends for late renal allograft loss, and the increasing incidence of chronic kidney disease and ESRD in this patient population, NIDDK and NIAID are sponsoring a workshop to discuss immunologic and non-immunologic factors that influence late allograft outcome.
Clinical investigators interested in late renal allograft dysfunction will discuss the current understanding of the problem, outline important questions that should be studied, and recommend strategies for future investigations.
