Smaller facet effusion in association with restabilization at the time of operation in Japanese patients with lumbar degenerative spondylolisthesis

Abstract

Facet effusion size was associated with the determination of whether the affected disc was stabilized or remained unstable at the time of operation. In particular, a smaller facet effusion size strongly suggested that the affected disc had been restabilized in the patients with lumbar degenerative spondylolisthesis.
