Why the study?
The aim was to understand how much surgical treatment can correct sagittal lumbosacral alignment to maintain sagittal balance in spondylolisthesis and demonstrate the effectiveness of posterior fixation.
Does posterior stabilization-fusion improve sagittal lumbosacral alignment in patients with lumbar spondylolisthesis?

Does posterior stabilization-fusion improve sagittal lumbosacral alignment in patients with lumbar spondylolisthesis?
Posterior fusion was associated with slip correction in spondylolisthesis; leaves open whether it improves long-term balance or outcomes.
Objective: Spondylolisthesis (SL) is a condition that occurs in 2-8% of the general population. Sagittal spinopelvic alignment determines the mechanical stress in the lumbosacral junction. The aim of this study is to understand how much we can correct sagittal lumbosacral alignment to maintain sagittal balance in SL by surgical treatment and to demonstrate the effectiveness of posterior fixation in maintaining sagittal balance. Materials and Methods: We retrospectively reviewed the cases operated with SL between January 2011 and June 2016. Wiltse classification was used to determine the type of SL. The parameters of sagittal balance (slip rate, slip angle, lumbar lordosis angle, lumbosacral kyphosis and sacral slope) were evaluated preoperatively and postoperatively.

Cevik et al. (2020) conducted an observational in Lumbar Spondylolisthesis. Posterior stabilization-fusion was evaluated on Sagittal balance parameters (slip rate, slip angle, lumbar lordosis angle, lumbosacral kyphosis, and sacral slope).
