Osteoporosis por inmovilización voluntaria

espanolDe forma clasica, multiples patologias fisicas se han considerado como causas de osteoporosis secundaria, entre ellas la inmovilizacion prolongada por enfermedades neurologicas paralizantes. Sin embargo, los desordenes psiquicos causantes de osteoporosis son escasos y poco documentados, a excepcion, logicamente, de la anorexia nerviosa. Presentamos un caso de depresion mayor que llevo al paciente a un encamamiento voluntario durante mas de 3 anos; este a su vez le ocasiono la aparicion de una osteoporosis intensa, con produccion de multiples fracturas. Si bien no se trata de una etiologia directa, la depresion debe considerarse, por la escasa actividad fisica que suele acompanarla (incluso en grado extremo, como en el caso presentado), como una posible causa de osteoporosis. EnglishClassically, some physical pathologies have been considered as secondary causes of osteoporosis, being the prolonged immobilization produced by some neurological diseases one of them. Nevertheless, psychological causes of osteoporosis are rare and less documented, maybe with the exception of anorexia nervosa. We present a case of major depression in a patient who was confined to bed for three years and led to a severe osteoporosis with multiple fractures. Although depression by itself is not a direct cause of osteoporosis, the poor physical activity that usually have these patients (in its highest degree in the present patient) should be taken into account as a possible cause of secondary osteoporosis.
