Diagnosis:

Sickle cell anemia

Discussion:

Lateral radiographs of the spine reveals central endplate depression with sparing of the anterior and posterior margins of the endplate. Several current names have been ascribed to these same changes seen in patients with hemoglobinopathy, such as Lincoln Log Sign, or H-shaped vertebra. Although not pathognomonic, these terms are typically reserved for a patient with Sickle-Cell disease.
