What is an allograft?

1. A bone graft from the same patient

2. A human bone graft from a person other than the patient

3. A synthetic bone graft

4. A type of graft used in dermatology

The correct answer is: A human bone graft from a person other than the patient

An allograft refers specifically to a bone graft that is taken from one person and implanted into another individual. This type of graft relies on the compatibility between donor and recipient, which is essential for the success of the procedure. Allografts are commonly used in various medical fields, particularly in orthopedic and dental procedures, to aid in tissue regeneration and repair. The reason for option B being correct lies in the specific definition and clinical application of an allograft. Using human tissue from donors can help achieve better outcomes in patients who need bone repair, especially when the patient's own bone is not available or insufficient. In contrast, other forms of grafts are described in the other options. For instance, a bone graft from the same patient is referred to as an autograft. Synthetic bone grafts, typically made from materials designed to mimic natural bone, are not classified as allografts. Finally, the reference to a graft used in dermatology suggests a different type of procedure unrelated to the definition of an allograft, which specifically pertains to bone grafting practices.
