本研究的第一个目标是建立可靠的踝关节、距下关节和后足关节对线的三维定义。这些对齐是基于三维形态学特征，这些特征来自承重计算机断层扫描获得的骨骼渲染。第二个目标是建立一个数据库，量化的踝关节，距下，和后足关节在一个健康的人口在负重双侧站立。该1级研究在95名正常受试者中进行，其中随机受试者被招募到对照组中。在中立、双侧、站立姿势下收集腿部的负重计算机断层扫描。在30名受试者中，扫描了左腿和右腿。每个关节的六个对齐参数是根据对骨骼的三维渲染进行的形态测量计算的。测试者内和测试者间的可靠性通过几个测试者的重复测量进行评估。对线参数的方差统计分析显示，年龄、性别或足侧无统计学差异。组内相关系数分析显示了良好的测试者间和测试者内的可靠性。得出的结论是，对准过程是全面和可靠的。因此，在不按性别或年龄分类的情况下，它可以用作量化与各种踝关节畸形相关的异常对线的基础。临床意义：对线方法和对照数据库可用于诊断踝关节、距下和后足错位。它也可以作为手术计划的基础，旨在恢复各种后足病变的正常对齐，如全踝关节置换术中的踝关节重新对齐。
The first goal of this study was to develop reliable three-dimensional definitions of alignment for the ankle, subtalar, and hindfoot joints. These alignments are based on three-dimensional morphological features derived from renderings of the bones obtained from weightbearing computer tomography. The second goal was to establish a database quantifying the alignment of the ankle, subtalar, and hindfoot joints in a healthy population during weightbearing bilateral standing. This level 1 study was performed on 95 normal subjects in which random subjects were recruited into a control group. Weightbearing computed tomography scans of the leg were collected in neutral, bilateral, standing posture. In 30 of the subjects, both the left and right leg was scanned. Six alignment parameters for each joint were calculated from morphological measurements conducted on three-dimensional renderings of the bones. Intra- and intertester reliability was assessed from repeated measurements by several testers. Analysis of variance statistics of the alignment parameters showed no statistical differences due to age, gender, or foot side. Intraclass correlation coefficient analysis showed excellent inter- and intratester reliability. It was concluded that the alignment process is comprehensive and reliable. Therefore, without classification by gender or age, it may be used as a foundation for quantifying abnormal alignment associated with various ankle deformities. Clinical significance: The alignment methodology and control database may be used to diagnose ankle, subtalar, and hindfoot misalignment. It can also serve as basis for surgical planning designed to restore normal alignment in various hindfoot pathologies, such as ankle realignment in total ankle replacement.
