SPACE (SPS ADVANCED CAGE): SPS Spacer for Intervertebral Fusion, Longitudinal, Prospective Clinical Study

"Arthrodesis is an operative modality also used in the treatment of multiple recurrences of herniated discs, stenosis (narrowing) of the spinal anal, degenerative and malformative spondylolisthesis.~The procedure can be performed with different surgical techniques, but in all cases it aims to achieve the same goal: to re-establish, through the use of spacers, the correct distance between two vertebral somes, in cases of disc degeneration, that are no longer able to fulfill their function; that is, they no longer absorb mechanical stresses and/or compress the nerve structures of the spine causing almost always unbearable (disabling) pain."
