ABSTRACT

Purpose:

The aim of the study is to evaluate sagittal spinopelvic parameters before and after lumbar stabilization surgeries.

Materials-Methods:

We inspected 60 patients who had been operated for lumbar stabilization between 2015 march and 2018 march retrospectively from the patient files. LL, PI, PT and SS angles were measured before and after surgery with Osirix® software.

Results:

A total of 60 patients included in the analyses. Mean age of the study group was 57.2±11.5 years, and M/F ratio was 12/48 (20% vs. 80%). Most frequent diagnosis was L1-L5 stenosis (n=10, 16.7%). Comparisons between study periods revealed that there was no significant difference for LL (p=0.85), PI (p=0.33), SS (p=0.79) and PT (p=0.34).

Conclusion:

It is important to always keep the targeted whole spine alignment in mind when performing spinal surgery. Sagittal spinopelvic parameters are not much affected with lumbar stabilization surgeries because the lumbosacral spine compensates so as to maintain the sagittal balance.
