Enfermedades osteocondensantes: una nueva visión clínico-radiológica soportada en la genética y la inmunoosteología

The alterations in osseous remodeling lead to the increase or decrease of the osseous mass, generating damage to the osseous micro-architecture, which increases the risk of fracture. The pathologies with increase in osseous density lead to different genetically directed osteocondensing processes. The osteocondensing is currently explained by alteration in the function of the osteoclast, associated with a deficient function of the osseous resorption, an alteration in the osteoblast function, which generates an abnormal increase in the osseous formation, or a homeostatic imbalance between the two processes; the clinical and radiological expression of these diseases can take place in early stages of the development, or in the adult life, depending on the recessive or dominant autosomic component, respectively. In this review, the classification based on the functional disorder of the bone cell is discussed, as well as the main clinical and radiological characteristics than permit a simple and applicable diagnostic approach in the clinical practice.
