    A fracture of the left iliac wing. The iliac crest has a large amount of red bone marrow, and thus it is the site of bone marrow harvests (from both sides) to collect the stem cells used in bone marrow transplantation. The iliac crest is also considered the best donor site for bone grafting when a large quantity of bone is needed. For example ...
