Abstract：
Septic arthritis is common in newborn calves due to poor birth and housing hygiene. This study investigated the pathological deformities caused by arthritis in the carpal bones of calves using geometric morphometry. The changes in the carpal joint bones of newborn calves with septic arthritis were examined through shape analysis. The study included 20 healthy Simmental calves and 30 Simmental calves with septic arthritis. Dorso-palmar x-ray images of the carpal joint were taken, and geometric morphometry was performed on these images using 25 landmarks. The first principal components (PC1) represented 26.92% of the total variation, while PC2 represented 13.84%. One of the most significant shape changes with increasing PC1 occurred in the os carpi intermedium. The study found that it was statistically possible to discriminate between radiometric carpal joint images of Simmental calves in the control and arthritis groups using geometric morphometry. In newborn calves with septic arthritis, the trochlea radi was located more proximally. There was an enlargement of the os carpi intermedium and a tendency towards the os carpi ulnare in female calves with septic arthritis. These results indicate significant bone deformation due to septic arthritis. Geometric morphometric methods can be clinically useful, as demonstrated in this study. Researchers can statistically explore these shape analyses, opening new avenues for research in this field. This method not only enhances our understanding of morphological changes but also provides a framework for clinical investigations and discoveries in related areas.
摘要：
由于出生和住房卫生差，化脓性关节炎在新生小腿中很常见。这项研究使用几何形态计量学调查了由小腿腕骨关节炎引起的病理畸形。通过形状分析检查了化脓性关节炎新生小腿腕关节骨的变化。该研究包括20只健康的西门塔尔小牛和30只患有化脓性关节炎的西门塔尔小牛。拍摄了腕关节的背侧掌侧X射线图像，使用25个地标对这些图像进行几何形态测量。第一主成分(PC1)占总变异的26.92%，而PC2占13.84%。随着PC1的增加，最重要的形状变化之一发生在中间的家兔中。研究发现，使用几何形态计量法可以在统计学上区分对照组和关节炎组中西门塔尔牛的放射性腕关节图像。在患有化脓性关节炎的新生小牛中，滑车radi位于更近的位置。在患有化脓性关节炎的雌性小牛中，中间的骨心扩大，并且有向骨心的趋势。这些结果表明由于化脓性关节炎引起的显著骨变形。几何形态测量方法可以在临床上有用，正如这项研究所证明的那样。研究人员可以统计探索这些形状分析，为这一领域的研究开辟了新的途径。这种方法不仅增强了我们对形态学变化的理解，而且为相关领域的临床研究和发现提供了框架。
