Allograft: Bone Graft from a Donor. Allograft bone used in spinal fusion is sourced from either living or deceased donors and subsequently undergoes processing to ensure sterility. 1 Cohen JD, Kanim LE, Tronits AJ, Bae HW. Allografts and Spinal Fusion. Int J Spine Surg. 2021 Apr;15 (s1):68-93. doi: 10.14444/8056.

Allograft, or bone harvested from a donor person or cadaver, can also be used and is typically acquired through ... Scrub techs were blinded to the bone processing method (Prep+ or manual) and asked to rate the
Bone or tissue transplanted from one part of a person's body to another part is called an autograft. Bone or tissue transplanted from the body of one person to another person is called an allograft. The term graft is commonly used …
An allograft bone graft is a surgical procedure where bone tissue harvested from a deceased donor is used to replace or augment the recipient's missing or defective bone. This method stands in stark contrast to autografts, where the bone is sourced from the patient's body, typically from the hip or rib (Thompson & Cohen, 2019).
The use of bone allografts is well-established in many bone regenerative procedures, but is associated with low rates of ingrowth due to pre-therapeutic graft processing. Cold physical plasma (CPP), a partially ionized gas that simultaneously generates reactive oxygen (O 2 ) and nitrogen (N 2 ) species, is suggested to be …
The presence of bone morphogenetic proteins in demineralized freeze-dried bone allograft (DFDBA) are responsible for developing hard tissues in intraosseous defects. The most common mode of sterilization of bone allografts, i.e., Gamma rays, have dramatic effects on the structural and biological properties of DFDBA, leading to loss of …
The use of human bone allografts in the practice of dentistry involves the steps of procurement, processing, use and tracking. Rigorous donor screening and aseptic …
In the first part of this study we compared two decellularization approaches resulting in chemically processed allografts (CPAs) or sonication-based processed allografts (SPAs). Each decellularization …
The use of massive bone allografts after the resection of bone tumours is still a challenging process. However, to overcome some issues related to the processing procedures and guarantee the best three-dimensional matching between donor and recipient, some tissue banks have developed a virtual tissue database based on the …
Introduction. On July 7, 2023, a state health department notified CDC that an otherwise healthy adult experienced symptoms of meningitis 5 weeks after spinal fusion surgery that incorporated a bone allograft product containing live cells; Mycobacterium tuberculosis was identified in the cerebrospinal fluid. On July 11, a different state health …
Twenty-four osteoarthrotic femoral heads were used to prepare fresh-frozen and freeze-dried irradiated cancellous bone. Each group was divided into four batches of different particle sizes, each batch containing 18 samples. The different particle sizes were obtained with a Retsch Cross Beater Mill SK 100, Noviomagus rotating bone mills with …
The implants were surrounded by a 2.5-mm gap into which morselized fresh frozen allograft bone was impacted. The bone graft was either (1) untreated or (2) rinsed in 37°C saline for 3 × 1 min. After 4 weeks, the animals were killed and implant fixation was evaluated by mechanical push-out and histomorphometry.
Allografts. Allografts provide surgeons with the tools they need to improve the lives of patients. They are used by surgeons in procedures when autografts and xenografts are either not appropriate or when surgeons and/or patients have expressed a preference for this option over others. Allograft tissues are generously donated human tissues that ...

Cold physical plasma (CPP), characterized by the generation of a plethora of short-lived oxygen (O 2) and nitrogen (N 2) species around body temperature, could be a promising tool for innovation in manufacturing process of bone allografts ( von Woedtke et al., 2020; Nonnenmacher et al., 2023 ). Thermal plasma spraying (>1,000°C) is already ...
In an ever-aging society the demand for bone-defect filling grafts continues to gain in importance. While autologous grafting still prevails as the gold standard, allografts and xenografts present viable alternatives with promising results. Physiochemical properties of a graft strongly depend on the processing method such as the …
PureCleanse TM processing technology has been developed by Australian Biotechnologies over several years to ensure that the removal blood, lipids and other unwanted proteins occurs throughout the allograft. A series of soaks using gentle chemicals removes the superfluous and unwanted debris from the surface. Followed by a …
In this article, we aim to review the available literature on allogenic bone and its derivatives as well as the influence of different preparation methods on its …
Allografts. Bone allografts are widely used in hand surgery. Bones harvested from cadavers are typically freeze-dried and sometimes undergo further processing such as ethylene oxide treatment or γ-radiation for further sterilization. Allografts can also be prepared fresh or frozen, but such preparations are rarely used in hand surgery.
Context 1. ... bone mill is used to grind the bone chips as much as possible to obtain a powder form (see Figure 2 ). Using a funnel and impactor (Figure 3), the prepared bone graft is...
Allograft vs. autograft bone grafts. Bone grafts treat traumatic injuries and help rejuvenate aging joints. Autografts use tissue from a person's own body, while allografts use tissue from ...
One processing technology takes advantage of using super-critical CO 2 (scCO 2), which currently seems the most gentle and effective technology of cleaning bone allografts. CO 2 is absolutely inert and such cannot react with proteins like growth factors inside the bone matrix.
Reports show that allograft bone used in a structural corticocancellous from consolidates with the host bone, but does not incorporate into a new vital bony structure. 9,16 Moreover, ... When using a bone mill instead of manually processing the graft material, one should be extremely careful to exclude all cartilage because the cartilage within ...
In musculoskeletal surgery, the treatment of large bone defects is challenging and can require the use of bone graft substitutes to restore mechanical stability and promote host-mediated regeneration. The use of bone allografts is well-established in many bone regenerative procedures, but is associated with low rates of ingrowth due to …
However, owing to the low level of patient acceptance of autografts, allografts (grafts from the same species) have become the most popular bone grafts in oral surgery. Among allografts available for the periodontal regeneration, freeze-dried bone allograft (FDBA) and the demineralized freeze-dried allograft (DFDBA) are the …
Successful use of allografts depends on many factors such as the procurement, processing, sterilization and the surgeon's surgical experience. Tissue banks have provided safe and sterile allografts for decades ranging from hard to soft tissue. Allografts are obtained from various tissues such as bone, tendon, amniotic membrane, …

Australian Allografts is committed to encouraging patients to become donors so that this critical source of bone graft can be collected, processed and distributed to enhance the life of a recipient in desperate need. The other source of allograft is cadaveric, or deceased donation. This occurs with the consent of the next of kin, someone who ...
A majority of bone grafting materials are made with particulate that is very granular in consistency, which, although suitable for certain applications, tends to fall apart and may not be contained very well. PrimaGen Advanced Allograft, however, utilizes a manufacturing process that creates fibers from the cortical bone, instead of particulate.
