Vertebral bone destruction in sickle cell disease: infection, infarction or both.

Abstract

Infectious and vaso-occlusive vertebral bone and joint destruction in two patients with sickle cell disease (SCD) are featured by H-shaped vertebrae, kyphotic angulation, osteolysis of endplates and collapse of intervertebral discs as shown by X-ray films and magnetic resonance imaging. Staphylococcal serology supported the diagnosis of staphylococcal osteomyelitis/spondylo-discitis in both SCD patients. The difficulties of establishing the causes and treatment of the osteoarthropathy in these particular cases are discussed in the light of the literature.
