摘要:

文题释义:

青少年特发性脊柱侧凸:是发生于青春期前后、原因不明的脊柱三维畸形,以脊柱侧方弯曲(Cobb角≥10°)伴椎体旋转为核心特征。
骶股耻骨角:为骶骨上终板中点、髋臼质心及耻骨联合上中点所构成的夹角。

摘要
背景:骶股耻骨角作为骨盆倾斜角的冠状位替代指标,它在青少年特发性脊柱侧凸不同Lenke分型中的关联特征尚未明确,这限制了骶股耻骨角在分型化评估中的临床应用。
目的:探讨Lenke1、5、6型青少年特发性脊柱侧凸患者骶股耻骨角与脊柱-骨盆参数(骨盆入射角、骨盆倾斜角、骶骨倾斜角、腰椎前凸角、胸椎后凸角及Cobb角)的相关性,建立分型特异性回归模型。
方法:回顾性分析191例青少年特发性脊柱侧凸患者的临床及影像学资料,其中Lenke1型60例、Lenke5型65例、Lenke6型66例。采用Pearson或Spearman分析各分型患者左右侧骶股耻骨角与骨盆入射角、骨盆倾斜角、骶骨倾斜角、腰椎前凸角、胸椎后凸角、Cobb角、矢状面轴向偏距的相关性,对有统计学意义的参数进行一元线性回归分析,构建线性回归模型。
结果与结论:①在Lenke1型青少年特发性脊柱侧凸患者中,右侧骶股耻骨角与骨盆倾斜角呈显著负相关(r=-0.366,P=0.028),左右侧骶股耻骨角与腰椎前凸角呈显著正相关(r=0.429,P=0.007;r=0.460,P=0.007)。在Lenke5型青少年特发性脊柱侧凸患者中,左右侧骶股耻骨角与腰椎前凸角呈显著正相关(r=0.415,P=0.007;r=0.400,P=0.007)。在Lenke6型青少年特发性脊柱侧凸患者中,左右侧骶股耻骨角与骨盆倾斜角呈显著负相关(r=-0.385,P=0.007;r=-0.376,P=0.014)。一元回归模型量化了上述关联(R²=0.13-0.21),其中Lenke5型青少年特发性脊柱侧凸患者骶股耻骨角与腰椎前凸角的回归方程斜率最大(0.85-0.89),Lenke6型青少年特发性脊柱侧凸患者骶股耻骨角与骨盆倾斜角的回归方程斜率为-0.52至-0.54。②结果表明,Lenke1、5、6型青少年特发性脊柱侧凸患者骶股耻骨角与脊柱-骨盆参数的关联存在明确分型特异性,Lenke1、5型以骶股耻骨角与腰椎前凸角正向关联为主,Lenke6型以骶股耻骨角与骨盆倾斜角双侧负关联为特征。

Abstract: BACKGROUND: The sacro-femoro-pubic angle, as a coronal plane alternative to the pelvic tilt angle, has an unclear association in different Lenke classifications of adolescent idiopathic scoliosis, limiting clinical application of the sacro-femoro-pubic angle in classification-specific assessment.
OBJECTIVE: To explore the correlation between the sacro-femoro-pubic angle and spine-pelvic parameters (pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, thoracic kyphosis, and main Cobb angle) in patients with Lenke types 1, 5, and 6 adolescent idiopathic scoliosis, and to establish classification-specific regression models. 
METHODS: Clinical and imaging data of 191 adolescent idiopathic scoliosis patients were retrospectively analyzed, including 60 with Lenke type 1, 65 with Lenke type 5, and 66 with Lenke type 6. Pearson or Spearman correlation analysis was used to examine the correlations between left/right sacro-femoro-pubic angle and pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, thoracic kyphosis, main Cobb angle, and sagittal vertical axis in each type. Parameters with statistical significance underwent univariate linear regression analysis to construct linear regression models.
RESULTS AND CONCLUSION: (1) In Lenke type 1 adolescent idiopathic scoliosis patients, right sacro-femoro-pubic angle showed a significant negative correlation with pelvic tilt (r=-0.366, P=0.028) and a significant positive correlation with lumbar lordosis (r=0.429, P=0.007; r=0.460, P=0.007). In Lenke type 5 adolescent idiopathic scoliosis patients, left/right sacro-femoro-pubic angle showed a significant positive correlation with lumbar lordosis (r=0.415, P=0.007; r=0.400, P=0.007). In Lenke type 6 adolescent idiopathic scoliosis patients, while left/right sacro-femoro-pubic angle showed a significant negative correlation with pelvic tilt (r=-0.385, P=0.007; r=-0.376, P=0.014). Univariate regression models quantified these associations (R²=0.13-0.21). Among them, the regression slope between sacro-femoro-pubic angle and lumbar lordosis was largest (0.85-0.89) in Lenke type 5 adolescent idiopathic scoliosis patients, while the regression slope between sacro-femoro-pubic angle and pelvic tilt ranged from -0.52 to -0.54 in Lenke type 6 adolescent idiopathic scoliosis patients. (2) The results indicate that the association between sacro-femoro-pubic angle and spine-pelvic parameters in Lenke types 1, 5, and 6 adolescent idiopathic scoliosis patients exhibits clear classification-specificity. Lenke types 1 and 5 are primarily characterized by a positive association between sacro-femoro-pubic angle and lumbar lordosis, while Lenke type 6 is characterized by a bilateral negative association between sacro-femoro-pubic angle and pelvic tilt.
