Question: 1 / 400

In bone grafting, what type of bone is obtained from the crest of the ilium?

Cancellous bone

In bone grafting, the type of bone obtained from the crest of the ilium is cancellous bone. Cancellous bone, also known as trabecular or spongy bone, is characterized by its porous structure and is found within the epiphyses of long bones and in the interior of other bones, including the ilium. The iliac crest is a common donor site for bone grafting due to its accessibility and rich supply of cancellous bone, which is beneficial for procedures that seek to promote bone healing and regeneration. Cancellous bone provides a large surface area and is typically more vascularized than cortical bone, facilitating better biological integration with the host bone when used in grafting.
