目的：探索Lenke 1型青少年特发性脊柱侧弯（ adolescent idiopathic scoliosis， AIS）患者的脊柱-骨盆矢状位参数与冠状位参数的相关性。方法：回顾2005年4月至2013年11月北京大学第三医院诊治的Lenke 1型AIS患者，在正、侧位片上测量和记录顶锥（apical vertebra， AV）位置、主胸弯Cobb角（main thoracic， MT），以及骨盆入射角（pelvic incidence， PI）、C7转移比值（C7 translation ratio， C7TR）等矢状位参数，运用统计软件进行参数间的比较和相关性分析。结果：共收集病例51例，其中男18例，女33例，平均年龄（14．9±2．0）岁，顶锥位置在T7～T11， MT为（49．6°±16．7°），PI值为（44．7°±6．7°）。 PI与PT、SS和LL，LL与SS和TK等有相关性（P均＜0．05）。不同腰椎修饰（ lumbar modifiers， LM）组的TK、LL、PT差异具有统计学意义，其他矢状位参数差异无统计学意义。 AV位置与脊柱-骨盆矢状位各参数相关性不显著， MT与TK、LL、SS显著相关，与PI相关性不显著。结论：Lenke 1型AIS的多数脊柱-骨盆矢状位参数间显著相关，形成以PI为核心的矢状位平衡调节链，部分冠、矢状位参数间有显著相关性。

Objective:To explore the relationship between spino-pelvic sagittal and coronal parameters in Lenke 1 group of adolescent idiopathic scoliosis (AIS).Methods:The subjects were retrospectively col-lected from 2005 to 2013.On the posteroanterior and lateral radiographs, apical vertebra ( AV) , Cobb an-gle of main thoracic curve (MT), pelvic incidence (PI), C7 translation ratio (C7TR) and other sagittal parameters were measured and recorded.Comparison and correlation studies were conducted between these parameters using specific softwares.Results: In the study, 51 subjects, including 18 males and 33 fe-males, were recruited, aged (14.9 ±2.0) years averagely.The apical vertebra ranged from T7 to T11,with mean MT being 49.6闭±16.7闭, and mean PI 44.7°±6.7°.Significant correlation existed between PI and PT, SS, LL, as well as between LL and SS, TK ( P <0.05) .Significant differences were found in TK, LL and SS among the different LM groups, but no difference in the other sagittal parameters.AV had no significant correlation with any sagittal parameter.MT was significantly correlated with TK, LL and SS, but its correlation with PI was not significant.Conclusion:Most of sagittal parameters were significantly corre-lated in Lenke 1 adolescent idiopathic scoliosis, forming a regulation chain of spine-pelvic sagittal balance on the basis of PI.Significant correlation exists between some sagittal and coronal parameters.
