Abstract
- Background: To evaluate the effects of correction in lumbar lordosis (LL) that have on full-body realignments in patients with degenerative lumbar scoliosis (DLS) who had undergone long sacroiliac fusion surgery. Methods: A multi-center retrospective study including 88 DLS patients underwent the surgical procedure of long sacroiliac fusion with instrumentations was performed. Comparisons of radiographic and quality-of-life (QoL) data among that at the pre-operation, the 3rd month and the final follow-up were performed. The correlations between the LL correction and the changes in other spinopelvic parameters were explored using Pearson-correlation linear analysis and linear regression analysis. The correlation coefficient (r) and the adjusted r<superscript>2</superscript>were calculated subsequently. Results: All radiographic and QoL data improved significantly (P&lt; 0.001) after the surgical treatments. The LL correction correlated (P&lt; 0.001) with the changes in the sacral slope (SS, r= 0.698), pelvic tilt (PT, r= -0.635), sagittal vertical axis (SVA, r= −0.591), T1 pelvic angle (TPA, r= −0.782), and the mismatch of pelvic incidence minus lumbar lordosis (PI–LL, r= −0.936), respectively. Moreover, LL increased by 1° for each of the following spinopelvic parameter changes (P&lt; 0.001): 2.62° for SS (r<superscript>2</superscript>= 0.488), −4.01° for PT (r<superscript>2</superscript>= 0.404), −4.86° for TPA (r<superscript>2</superscript>= 0.612), −2.08° for the PI–LL (r<superscript>2</superscript>= 0.876) and -15.74 mm for SVA (r<superscript>2</superscript>= 0.349). Changes in the thoracic kyphosis (r= 0.259) and pelvic femur angle (r= 0.12) were independent of the LL correction, respectively. Conclusions: LL correction correlated significantly to the changes in spinopelvic parameters; however, those independent variables including the thoracic spine and hip variables probably be remodeled themselves to maintain the full-body balance in DLS patients underwent the correction surgery.
