ARTICLE HIGHLIGHTS
Research background

The impact of single-segment midline lumbar fusion (MIDLF) on sagittal lumbar-pelvic alignment for management of degenerative lumbar diseases is still unknown.

Research motivation

Comparing the impact of MIDLF and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) on sagittal lumbar-pelvic parameters can help to better understand minimally invasive lumbar surgery.

Research objectives

To compare the effects of single-segment MIDLF and MIS-TLIF on sagittal lumbar-pelvic parameters.

Research methods

We retrospectively analyzed 63 patients with degenerative lumbar diseases who underwent single-segment MIDLF or MIS-TLIF. The sagittal lumbar-pelvic parameters and clinical outcomes of the two groups were compared.

Research results

Both MIDLF and MIS-TLIF can improve lumbar lordosis (LL), lower LL, L5 incidence (L5I), and L1 axis and S1 distance (LASD). Nevertheless, MIDLF showed a better ability to improve pelvic parameters than MIS-TLIF. However, there was no significant difference between the two groups in terms of clinical outcomes at the final follow-up.

Research conclusions

Short-segment MIDLF and MIS-TLIF can equally improve sagittal lumbar parameters such as LL, Lower LL, L5I, and LASD in the treatment of lumbar degenerative diseases. However, MIDLF had a larger impact on pelvic parameters than MIS-TLIF.

Research perspectives

MIDLF is a good choice for the treatment of short-segment degenerative lumbar diseases.
