To analyze the relationships between coronal and sagittal spinopelvic parameters in degenerative lumbar kyphoscoliosis (DLKS).
We enrolled 75 patients with DLKS for a radiographic study between January 2016 and September 2018. Correlations between coronal and sagittal spinopelvic radiographic parameters were analyzed. Then patients were divided into 2 groups: sagittal balanced group (SVA< = 5 cm, 30 patients) and sagittal imbalanced group (SVA >5 cm, 45 patients), and relevant parameters were compared.
The Cobb angle and lumbar lordosis of the DLKS patients were 24.87 ± 11.59° and 17.26 ± 12.24°, respectively. The average age was 68 years old (range: 42-82), and the sex ratio was 2.6:1 (female: 54 patients; male: 21 patients). 50 patients (66.7%) located convexity of the curve at left side, while 25 patients (33.3%) at right side. The Cobb angle correlated with LL-TK (r = -0.228, p = 0.049), LL (r = -0.255, p = 0.027) and SS (r = -0.232, p = 0.045). There were significant differences in PI-LL (t = -3.484, P = 0.001), LL-TK (t = 2.354, P = 0.023), PI (t = -3201, P = 0.002) and PT (t = -2.521, P = 0.014) between sagittal balanced and imbalanced group.
In degenerative lumbar kyphoscoliosis, there are some correlations between coronal and sagittal spinopelvic parameters. Moreover, PI-LL, LL-TK, PI, PT were significantly different between sagittal balanced and imbalanced DLKS patients.
分析退变性腰椎后凸侧凸（DLKS）中冠状面和矢状面脊柱骨盆参数之间的关系。
2016年1月至2018年9月，我们纳入了75例DLKS患者进行影像学研究。分析冠状面和矢状面脊柱骨盆影像学参数之间的相关性。然后将患者分为两组：矢状面平衡组（SVA≤5 cm，30例患者）和矢状面失衡组（SVA＞5 cm，45例患者），并比较相关参数。
DLKS患者的Cobb角和腰椎前凸分别为24.87±11.59°和17.26±12.24°。平均年龄为68岁（范围：42 - 82岁），性别比为2.6:1（女性：54例患者；男性：21例患者）。50例患者（66.7%）曲线凸侧位于左侧，25例患者（33.3%）位于右侧。Cobb角与LL - TK（r = -0.228，p = 0.049）、LL（r = -0.255，p = 0.027）和SS（r = -0.232，p = 0.045）相关。矢状面平衡组和失衡组在PI - LL（t = -3.484，P = 0.001）、LL - TK（t = 2.354，P = 0.023）、PI（t = -3.201，P = 0.002）和PT（t = -2.521，P = 0.014）方面存在显著差异。
在退变性腰椎后凸侧凸中，冠状面和矢状面脊柱骨盆参数之间存在一些相关性。此外，矢状面平衡和失衡的DLKS患者在PI - LL、LL - TK、PI、PT方面存在显著差异。
