The determination of factors affecting curve flexibility is important in idiopathic scoliosis patients with regard to the Risser sign. The objective of this retrospective study was to identify factors affecting curve flexibility in patients with skeletally immature and mature idiopathic scoliosis.
The records of all patients with idiopathic scoliosis who received surgical treatment from July 2001 to August 2008 at our hospital were screened. The Risser sign was used to separate the patients into a skeletally mature group (Risser grade = 5) and skeletally immature group (Risser grade < 5). Data recorded and compared were flexibility (%), bending angle (°), apical vertebral rotation (°), Cobb angle (°), curve location, prior use of brace treatment, and number of vertebrae in the curve.
The study cohort consisted of 217 patients (34 males, 183 females) in the Risser grade < 5 group and 124 (21 males, 103 females) in the Risser grade = 5 group. Multiple linear regression analysis revealed that the Cobb angle and the curve location significantly affected curve flexibility in the Risser grade < 5 group, whereas in the Risser grade = 5 group, Cobb angle and age significantly affected flexibility.
Cobb angle and curve location influence main curve flexibility in skeletally immature adolescent idiopathic scoliosis, and Cobb angle and age influence curve flexibility in skeletally mature adult scoliosis. Measurement of these values may aid in the evaluation of treatment options and preoperative planning.
对于特发性脊柱侧凸患者，确定影响脊柱侧弯柔韧性的因素对于Risser征而言很重要。这项回顾性研究的目的是确定影响骨骼未成熟和成熟的特发性脊柱侧凸患者脊柱侧弯柔韧性的因素。
筛选了2001年7月至2008年8月在我院接受手术治疗的所有特发性脊柱侧凸患者的记录。使用Risser征将患者分为骨骼成熟组（Risser分级=5）和骨骼未成熟组（Risser分级<5）。记录并比较的数据包括柔韧性（%）、弯曲角度（°）、顶椎旋转（°）、Cobb角（°）、侧弯位置、先前是否使用过支具治疗以及侧弯中的椎体数量。
研究队列包括Risser分级<5组的217例患者（34例男性，183例女性）和Risser分级=5组的124例患者（21例男性，103例女性）。多元线性回归分析显示，Cobb角和侧弯位置在Risser分级<5组中显著影响脊柱侧弯柔韧性，而在Risser分级=5组中Cobb角和年龄显著影响柔韧性。
Cobb角和侧弯位置影响骨骼未成熟的青少年特发性脊柱侧凸的主侧弯柔韧性，Cobb角和年龄影响骨骼成熟的成人脊柱侧凸的脊柱侧弯柔韧性。测量这些值可能有助于评估治疗方案和术前规划。
