Taking a Bone Marrow Sample

Bone marrow samples are usually taken from the hipbone (iliac crest). The person may lie on one side, facing away from the doctor, with the knee of the top leg bent. After disinfecting the skin and numbing the area over the bone with a local anesthetic, the doctor inserts a needle into the bone and withdraws the marrow.
