| Abstract:Objective To compare radiographic outcomes of segmental alignment of patients with lumbar degenerative spondylolisthesis (DS) after single technique and combined posterior fixation in oblique lumbar interbody fusion (OLIF) procedure, and to evaluate the effect of posterior fixation on lumbar segmental alignment. Methods A total of 63 patients (73 DS segments) with DS underwent OLIF surgery without posterior osteotomy with or without additional posterior fixation from July 2017 to December 2019 were selected. Seventeen patients were treated with single OLIF and 46 patients were treated with OLIF combined with posterior fixation. There were 53 patients underwent single-level surgery and 10 patients underwent double-level surgery. The radiographic parameters including disc height (DH), slip ratio (SR), and segmental lordosis (SL) were measured on plain radiographs before operation and 3 d after operation. Results These were 21, 52 segments in single OLIF and OLIF combined with posterior fixation groups, respectively. There was no significant difference among facet degeneration, level fused, and cage position between the two groups. In single OLIF and OLIF combined with posterior fixation groups, SL about improved 1.5° and 5.0°, and SR about improved 5.3% and 11.6%, respectively (P<0.001). SL improved 3.5° and SR improved 6.3% by posterior fixation based on OLIF. Conclusions OLIF combinded with posterior fixation has better improvement effect on radiographic parameters in DS patients than single OLIF, especially in SR and SL. |
