MIS TLIF for spondylolisthesis
Abstract
Introduction Minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) is a common surgical option for degenerative spondylolisthesis (DS). However, its effectiveness
RI PT
for isthmic spondylolisthesis (IS) is still controversial. No current studies have directly compared perioperative and postoperative results including various radiologic parameters

between IS and DS after MIS TLIF.
Purpose The purpose of this study is to compare the clinical and radiologic results between

isthmic and degenerative spondylolisthesis after MIS TLIF.
Methods This is a retrospective study of 41 patients who underwent MIS TLIF for single segment, grade 1 or 2 IS (n=18) and DS (n=23). The same surgical techniques and procedure were applied to both groups. Perioperative outcomes (operation time, blood loss, hospital stay,

Results There were no significantly different perioperative results between groups. Mean VAS and ODI scores significantly improved postoperatively in both groups, but were not significantly different between groups at each follow-up point. Radiologic parameters were not significantly different between groups except disc height and degree of spondylolisthesis. The disc heights were increased postoperatively (IS: 6.79 to 9.22 mm; DS: 8.18 to 8.97 mm) in both groups and there were significant differences preoperatively. In addition, disc height 2
