Résumé
Vertebra plana is a concept introduced by Calvé in 1925 to name a process characterized by the collapse of a single vertebra with no involvement of the discs, widening of the intervertebral space of at least one third compared with normal width, and an increase in the density of the collapsed vertebra. Because of its benign and self-limiting nature, this entity was originally thought to be an osteochondritis. Later publications did not corroborate this view and connected this entity initially with eosinophilic granuloma and subsequently with additional malignant infiltrating tumoral processes, in particular with Ewing's sarcoma and lymphomas, thus posing difficulties for its management. The initial concept was extended in 1990 to crushed and wedged vertebrae, including developmental abnormalities such as bone dysplasias. The present article provides a general review of vertebra plana, including the concept, etiology and pathogenesis of related processes, clinical findings and diagnosis. We also discuss the debate on the benign or malignant nature of vertebra plana and on the need for an immediate biopsy versus observation, as well as the therapeutic orientations.
