Tibial torsion is important to be factored in during calculations of angular deformities of the lower extremity. Three methods are commonly used, thigh foot angle, measurement of transmalleolar axis with proximal tibia or knee as a reference, and Computerized tomography. The purpose of the current study was to find out the effectiveness of clinical methods and compare CT based method for tibial torsion.
A total of 68 limbs (34 subjects) were included. Tibial torsion was measured using thigh foot angle, transmalleolar axis in relation to knee forward position (Knee ankle axis) and CT based evaluation using Jend method.
Pearson correlation coefficient showed strong correlation between CT values and thigh foot angle (r = 0.848) as well as between CT values and Knee ankle axis (r = 0.889). Scatter plots also showed a linear distribution.
Both thigh foot angle and Knee ankle axis provide reliable alternative to ionizing CT in measuring tibial torsion.
在计算下肢角畸形时，胫骨扭转很重要，需要考虑在内。常用的方法有三种，即大腿足角法、以近端胫骨或膝关节为参照测量经踝轴法以及计算机断层扫描法。本研究的目的是探究临床方法的有效性，并比较基于计算机断层扫描的胫骨扭转测量方法。
共纳入68条肢体（34名受试者）。采用大腿足角法、相对于膝关节前位的经踝轴法（膝踝轴法）以及基于计算机断层扫描的Jend法评估胫骨扭转。
皮尔逊相关系数显示，计算机断层扫描值与大腿足角之间（r = 0.848）以及计算机断层扫描值与膝踝轴之间（r = 0.889）存在强相关性。散点图也显示出线性分布。
在测量胫骨扭转时，大腿足角法和膝踝轴法都是可靠的替代电离计算机断层扫描的方法。
