ABSTRACT
PURPOSE:
This study aimed to explore the relationships between lumbar lordosis (LL) correction and improvement of postoperative global sagittal alignment and to establish corresponding linear regressions to predict the change in global tilt (GT) based on the corrected LL following adult spinal deformity (ASD) surgery.METHODS:
A total of 240 ASD patients who underwent lumbar correction were enrolled in this multicentre study. The following sagittal parameters were measured pre- and postoperatively thoracic kyphosis (TK), LL, upper and lower LL (ULL and LLL), pelvic tilt (PT), sagittal vertical axis (SVA) and GT. The correlations among the changes in GT (â³GT), SVA (â³SVA), PT (â³PT), TK (â³TK), LL (â³LL), ULL (â³ULL) and LLL (â³LLL) were assessed, and linear regressions were conducted to predict â³GT, â³SVA, â³PT and â³TK from â³LL, â³ULL and â³LLL.RESULTS:
â³LL was statistically correlated with â³GT (r = 0.798, P < 0.001), â³SVA (r = 0.678, P < 0.001), â³PT (r = 0.662, P < 0.001) and â³TK (r = - 0.545, P < 0.001), and the outcomes of the linear regressions are â³GT = 3.18 + 0.69 × â³LL (R2 = 0.636), â³SVA = 4.78 + 2.57 × â³LL (R2 = 0.459), â³PT = 2.57 + 0.34 × â³LL (R2 = 0.439), â³TK = 7.06-0.43 × â³LL (R2 = 0.297). In addition, â³LLL had more correlations with â³GT, â³SVA and â³PT, while â³ULL had more correlations with â³TK.CONCLUSION:
Surgical correction of LL could contribute to the restoration of global sagittal morphology following ASD surgery. These models were established to predict the changes in sagittal parameters, in particular â³GT, determined by â³LL, which has not been previously done and may help to customize a more precise correction plan for ASD patients.Palavras-chave
