Experiencia y resultados preliminares en el uso de cilindros intersomáticos para la artrodesis lumbar

Chronic low back pain is a medical cause of disability in which conservative management is often not effective. As an alternative, interbody fusion with cylinders offers several advantages as compared to other surgical methods of fusion. This technique has been recently introduced in our Country. The preliminary results of 16 patients managed in our Department are shown. From 1997 to December 2000, eleven BAK devices and 5 LIFEC have been implanted. Ten patients had a minimum follow-up of 1 year and these constitute the series evaluated. Seven patients (70%) were free of pain. Four patients (40%) returned to their previous job. Six patients (60%) did not need medical treatment. The good results with this technique encourage us and suggest that these devices are a valid option for the management of chronic low back pain.
