我们研究了远端桡尺关节（DRUJ）冲击试验的可靠性和准确性，使用五个新鲜冷冻尸体标本三角纤维软骨复合体（TFCC）完整，TFCC切片的手腕。肱骨和尺骨近端固定。允许尺骨在背掌方向上平移而不旋转，并且允许桡骨自由移动。四个磁跟踪系统的传感器被连接到桡骨和尺骨，以及每个检查员的拇指指甲。在TFCC切片之前和之后，五名检查员进行了DRUJ冲击试验。我们使用了两种技术：握住和不握住腕骨到桡骨（分别为握住和不握住测试）。我们比较了骨-骨（绝对DRUJ）运动的幅度与检查者的钉-钉（相对DRUJ）运动的幅度。组内相关系数（ICC）为0.92（持有）和0.94（非持有）。评分者间ICC分别为0.84（持有）和0.75（非持有）。绝对和相对运动幅度分别为11.5mm和11.8mm（p
We investigated the reliability and accuracy of the distal radioulnar joint (DRUJ) ballottement test using five fresh-frozen cadaver specimens in triangular fibrocartilage complex (TFCC)-intact, and TFCC-sectioned wrists. The humerus and proximal ulna were fixed. The ulna was allowed to translate in dorsopalmar directions without rotation, and the radius was allowed to move freely. Four sensors of a magnetic tracking system were attached to the radius and ulna, and the nails of each examiner's thumbs. Five examiners conducted the DRUJ ballottement test before and after TFCC sectioning. We used two techniques: With holding and without holding the carpal bones to the radius (holding and non-holding tests, respectively). We compared the magnitudes of bone-to-bone (absolute DRUJ) movement with that of the examiner's nail-to-nail (relative DRUJ) movement. The intrarater intraclass correlation coefficients (ICCs) were 0.92 (holding) and 0.94 (non-holding). The interrater ICCs were 0.84 (holding) and 0.75 (non-holding). Magnitudes of absolute and relative movements averaged 11.5 and 11.8mm, respectively (p
