The differences in sagittal spino-pelvic alignment between adults with chronic low back pain (LBP) and the normal population are still poorly understood. In particular, it is still unknown if particular patterns of sagittal spino-pelvic alignment are more prevalent in chronic LBP. The current study helps to better understand the relationship between sagittal alignment and low back pain.
To compare the sagittal spino-pelvic alignment of patients with chronic LBP with a cohort of asymptomatic adults. Sagittal spino-pelvic alignment was evaluated in prospective cohorts of 198 patients with chronic LBP and 709 normal subjects. The two cohorts were compared with respect to the sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), lumbar lordosis (LL), lumbar tilt (LT), lordotic levels, thoracic kyphosis (TK), thoracic tilt (TT), kyphotic levels, and lumbosacral joint angle (LSA). Correlations between parameters were also assessed.
Sagittal spino-pelvic alignment is significantly different in chronic LBP with respect to SS, PI, LT, lordotic levels, TK, TT and LSA, but not PT, LL, and kyphotic levels. Correlations between parameters were similar for the two cohorts. As compared to normal adults, a greater proportion of patients with LBP presented low SS and LL associated with a small PI, while a greater proportion of normal subjects presented normal or high SS associated with normal or high PI.
Sagittal spino-pelvic alignment was different between patients with chronic LBP and controls. In particular, there was a greater proportion of chronic LBP patients with low SS, low LL and small PI, suggesting the relationship between this specific pattern and the presence of chronic LBP.
慢性下腰痛（LBP）患者矢状位脊柱骨盆排列与正常人群的差异仍知之甚少。特别是，慢性 LBP 中是否存在特定的矢状位脊柱骨盆排列模式更为普遍仍不清楚。本研究有助于更好地理解矢状位排列与腰痛之间的关系。
为了比较慢性 LBP 患者与无症状成年人的矢状位脊柱骨盆排列。前瞻性队列研究了 198 例慢性 LBP 患者和 709 例正常受试者的矢状位脊柱骨盆排列。比较了两组的骶骨倾斜角（SS）、骨盆倾斜角（PT）、骨盆入射角（PI）、腰椎前凸（LL）、腰椎倾斜角（LT）、前凸水平、胸椎后凸（TK）、胸椎倾斜角（TT）、后凸水平和腰骶关节角（LSA）。还评估了参数之间的相关性。
慢性 LBP 患者的矢状位脊柱骨盆排列在 SS、PI、LT、前凸水平、TK、TT 和 LSA 方面与 SS、PI、LT、前凸水平、TK、TT 和 LSA 方面存在显著差异，但在 PT、LL 和后凸水平方面没有差异。两组之间的参数相关性相似。与正常成年人相比，更多的慢性 LBP 患者表现为 SS 和 LL 降低，PI 较小，而更多的正常受试者表现为 SS 和 LL 正常或升高，PI 正常或升高。
慢性 LBP 患者的矢状位脊柱骨盆排列与对照组不同。特别是，慢性 LBP 患者中 SS、LL 和 PI 较小的比例较大，表明这种特定模式与慢性 LBP 的存在之间存在关系。
