Fuga intrarraquídea de cemento biológico tras cifoplastia. Evolución a largo plazo. Presentación de un caso y revisión de la literatura

. Most of the papers in the literature discuss the behaviour of the reinforcement material inside a bony environment, but they do not refer to the evolution of the cement outside the vertebral space. We have appreciated in our case that the leaked cement is not being substituted for bone but it suffers a process of progressive resorption. The extravasation of the vertebral reinforcement material is an important and potentially serious complication of the vertebral augmentation techniques. To avoid this, a very precise chirurgical technique is necessary, under radiological guidance. Biocompatibility, biodegradability and osteoconductivity are the main advantages of biological cemnets. We base the choice of the cement on the balloom/trabeculae interaction.
