Abstract

Background: The present study aimed to compare clinical outcomes and radiographic results of oblique lumbar interbody fusion (OLIF) with transforaminal lumbar interbody fusion (TLIF) in patients with lumbar spondylolisthesis.

Methods: We retrospectively reviewed and compared 28 patients who underwent OLIF (OLIF group) and 35 who underwent TLIF (TLIF group). The operation time, intraoperative hemorrhage, bed rest duration, and length of hospital stay were compared between the 2 groups. Clinical results were evaluated with the ODI and VAS for back and leg pain. Radiological results were evaluated with disc height (DH), foraminal height (FH), fused segment lordosis (FSL) and lumbar lordosis (LL).

Results: The OLIF group had less intraoperative blood loss, shorter operative time, bed rest time, and hospital stay than TLIF group (P<0.05). The OLIF group had lower VAS scores for back pain and lower VAS scores for leg pain after surgery compared with before surgery (P<0.05), The OLIF group had lower ODI after surgery compared with before surgery (P<0.05) .The was no significant difference in decrease value in VAS and ODI after surgery between the two groups (P>0.05). No significant differences were found in DH, FH and LL between the 2 groups preoperatively (P>0.05). The OLIF group showed higher DH and FH than the TLIF group at all time points (P<0.05). No significant differences were found in FSH between the 2 groups at any time point.

Conclusions: OLIF has similar good long-term clinical outcomes of TLIF with the additional benefits of less initial postoperative pain, early rehabilitation, shorter hospitalization, and fewer complications.
