目的了解支点弯曲像柔韧性(FBF)与手术治疗成人特发性脊柱侧凸矫形率(CR)的关系,探讨支点弯曲柔韧性对成人脊柱侧凸矫形手术效果的评估能力.方法对69例进行手术治疗的特发性成人脊柱侧凸患者拍摄术前站立位、支点弯曲位和术后站立位X线片,测量其胸段/胸腰段脊柱侧凸的Cobb角,计算支点弯曲柔韧性和矫形率,对二者进行统计学分析.结果使用数据分析软件SPSS 10.0对FBF和CR率进行回归分析,得出:CR=0.213+0.768×FBF,即支点弯曲柔韧性每提高1个单位,矫形率提高0.768个单位(P<0.01).结论支点弯曲矫形率和手术矫形率存在明显的线性关系,使用此方程,可对符合条件的多病例样本进行矫形率预测,能够客观评估新的矫形器械或矫形方法的矫形效果.

Objective To study the relationship between the fulcrum bending flexibility(FBF) and correction rate (CR) of adult idiopathic scoliosis, and to explore the ability of FBF to assess the correction effect in relation to fulcrum bending flexibility. Methods 69 patients with adult idiopathic seoliosis with structural curves at thoracic or lumbarthoracic segments, 16 males and 53 females, aged 26.5(19-53) were treated by pedicle screws instrumentation. Pre-opemtive standing and fulcrum bending films and postoperative standing X-ray film were taken. Cobb angle was measured. The data underwent regression analysis with the software SPSS 10.0. Results A regression formula was established:CR =0.213 +0.768×FBF with P <0.01. Conclusion A definite linear relation exists between the FBF and CR of adult idiopathic scoliosis. By using the formula in proper samples, the effects of new instrumentation or correction technique can be objectively assessed.
