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 scoliosis 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-operative 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 x 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.
目的
研究成人特发性脊柱侧凸的支点弯曲柔韧性（FBF）与矫正率（CR）之间的关系，并探讨FBF评估与支点弯曲柔韧性相关的矫正效果的能力。
方法
69例胸段或胸腰段存在结构性侧弯的成人特发性脊柱侧凸患者，男性16例，女性53例，年龄26.5（19 - 53）岁，接受椎弓根螺钉内固定治疗。术前拍摄站立位和支点弯曲位X线片，术后拍摄站立位X线片。测量Cobb角。数据采用SPSS 10.0软件进行回归分析。
结果
建立回归公式：CR = 0.213 + 0.768×FBF，P < 0.01。
结论
成人特发性脊柱侧凸的FBF与CR之间存在明确的线性关系。通过在适当样本中使用该公式，可以客观评估新的内固定器械或矫正技术的效果。
