purpose. To compare early outcome of transforaminal lumbar interbody fusion (TLIF) for lytic versus degenerative spondylolisthesis. Methods. 14 women and 8 men aged 20 to 60 (mean, 36) years underwent TLIF for lytic (n=15) or degenerative (n=7) spondylolisthesis. Of the 15 patients with lytic spondylolisthesis, 9 involved L4/ L5 and 6 L5/S1. Of the 7 patients with degenerative spondylolisthesis, 3 involved L4/L5, 2 L5/S1, one L2/L3, and one L3/L4. The spondylolistheses were classified as grade II (n=15), grade III (n=4), and retrolisthesis (n=3). 11 patients with lytic and 2 with degenerative spondylolisthesis had sensory deficits (n=12), motor deficits (n=9), and diminished reflexes (n=7). Visual analogue score (VAS) for pain and the Oswestry Disability Index (ODI) of each patient were assessed at months 3, 6, and 12, and 6 monthly thereafter. Fusion status was assessed by radiologists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
