Background. Human allografts have been used in orthopedic surgery for many decades. In the 19th century William Macewen 13 described the successful use of allogeneic cortical bone fragments to graft a replacement for a missing humeral midshaft. Over 100 years ago, Fred Albee published a long list of surgical uses of bone allografts including applications and stated, "[I have] been able ...

Preparation of the host bed is important for allograft incorporation. The host bed should be free of infection prior to grafting. Whenever possible, the allograft should be securely fixed to the host bone to aid in incorporation and to prevent displacement of the graft.

Core tip: Allograft tissues from human donor like bone, skin, amniotic membrane and other soft tissues provide an excellent alternative to autografts for clinical use. However, major concern with the use of allografts is the risk of infectious disease transmission.

In an everaging society the demand for bonedefect 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 decellularization protocol. In addition, the physiochemical ...

Allografts promote bone fusion and eliminate the need for additional surgery. Ideally, a bone graft must contain cells, growth factors, and chemicals to induce bone formation and provide a structural scaffolding where the boneforming cells can lay down new bone. 1 Cohen JD, Kanim LE, Tronits AJ, Bae HW.

Abstract. Bone grafts have traditionally come from four sources: the patients' own tissue (autograft), tissue from a living or cadaveric human donor (allograft), animal donors (xenograft) and synthetic artificial biomaterials (ceramics, cement, polymers, and metal). However, all of these have advantages and drawbacks. The most commercially ...

Allografts Allografts are transplanted organs or tissue from one individual to another of the same species with a different genotype. For example, a transplant from one person to another, but not an identical twin, is an allograft. Allografts account for many human transplants, including those from cadaveric and living donors. Also known as an allogeneic [.]

Fracture surgery is regularly challenged by the presence of bone defects, reduced mechanical stability, and a lack of bone healing, wherein bone substitutes can be useful. Bone autograft is the gold standard, but has side effects from donor sites and is less useful when there is a need for larger amounts [1,2]. The alternatives are allograft and demineralised bone matrix (DBM), where there are ...
