Although there is some theoretical risk for disease transmission, the use of allografts that have undergone rigorous donor screening, serological testing, and formal processing has significantly reduced this risk. The FDA has regulated this field very closely since 1993 to ensure the safety of allograft transplant.

As allograft processing techniques reduce its mechanical strength, fresh, unprocessed allograft has superior characteristics compared to processed bone. Unfortunately, for fear of possible disease transmission and host immunogenic response, fresh allografts are not very popular nowadays [ 4, 7, 21 ].

In Germany, bone allografts are widely used and their application in clinics has increased over the years. 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. 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.
