This study aimed to determine normal values of three parameters commonly used to determine malunion by investigating intact scaphoids on sagittal computed tomography images from healthy individuals. We analysed 62 normal scaphoids and found the mean height-length ratio, lateral intrascaphoid angle and dorsal cortical angle to be 0.58, 27° and 128°, respectively. These measurements had good-to-excellent, poor-to-moderate and moderate-to-good inter- and intra-rater reliabilities, respectively. This study provides information on normal parameters of the scaphoid that may inform clinical decision making when assessing malunion. We suggest that the lateral intrascaphoid angle should be used with great caution as a measure of deformity. III.
本研究旨在通过研究健康个体的矢状位 CT 图像上的完整舟骨，确定三个常用于判断畸形愈合的参数的正常值。我们分析了 62 个正常舟骨，发现其平均高度-长度比、舟骨外侧内倾角和背侧皮质角分别为 0.58、27°和 128°。这些测量值的组内和组间可信度分别为良好到优秀、差到中等和中等到良好。本研究提供了有关舟骨正常参数的信息，这些信息可能有助于在评估畸形愈合时为临床决策提供依据。我们建议谨慎使用舟骨外侧内倾角作为衡量畸形的指标。III。
