Here, we evaluated the failure to preserve or restore adequate spinopelvic alignment following lumbosacral instrumented fusions for degenerative disease.
Patients undergoing lumbosacral instrumented fusions for degenerative spine disease underwent; standing lumbopelvic X-rays and lumbar MRI scans obtained both preoperatively and 1 year postoperatively. Parameters measured included lumbar lordosis (LL), L4-S1 angle, pelvic incidence (PI), and LL-PI mismatch.
Fifty patients were followed for 1 year following lumbopelvic fusion. There was a statistically significant difference in the L4-S1 angle between patients with good versus poor clinical outcomes at 1 year postoperative; the LL-PI mismatch showed a strong positive correlation with better outcome scores.
Preservation of an adequate LL/other lumbosacral parameters favorably impacts patients' outcomes following lumbosacral fusion for degenerative disease.
在此，我们评估了因退行性疾病行腰骶部器械融合术后未能保留或恢复足够的脊柱骨盆对线情况。
因退行性脊柱疾病接受腰骶部器械融合术的患者在术前及术后1年进行了站立位腰骶部X线检查和腰椎MRI扫描。测量参数包括腰椎前凸（LL）、L4-S1角、骨盆入射角（PI）以及LL-PI失配。
50例患者在腰骶部融合术后随访1年。术后1年临床结局良好与不良的患者之间，L4-S1角存在统计学显著差异；LL-PI失配与更好的结局评分呈强正相关。
保留足够的LL/其他腰骶部参数对因退行性疾病行腰骶部融合术患者的结局有积极影响。
