Infarction tends to occur in the diaphyses of small tubular bones in children and in the metaphyses and subchondrium of long bones in adults. Because of the anatomic distribution of the blood vessels supplying the vertebrae, infarction affecting the central part of the vertebrae (fed by a spinal artery branch) results in the characteristic H vertebrae of sickle cell disease. The outer portions of the plates are spared because of the numerous apophyseal arteries.
