Seudoclaudicación; Estenosis raquídea central; Estenosis del agujero vertebral
Es un estrechamiento de la médula espinal que causa presión sobre ésta, o estrechamiento de las aberturas (llamadas agujeros intervertebrales) por donde los nervios raquídeos salen de la columna vertebral.
La estenosis raquídea por lo general ocurre a medida que una persona envejece y los discos se vuelven más resecos y empiezan a encogerse. Al mismo tiempo, los huesos y los ligamentos de la columna vertebral se hinchan o crecen debido a la artritis o a la hinchazón (inflamación) crónica.
La estenosis raquídea también puede ser causada por:
