The study aims to analyse the normal anatomical and radiographical features of the Manus of the southern Aswanian-adapted Arabian one-humped camel, providing crucial data for diagnosing and treating various ailments. Our study was applied to 10 cadaver forelimbs of adult male one-humped camels (4-5 years old) for an explanation of the gross anatomy of the bones of the Manus region from under the carpal bones by using traditional techniques, including the gross anatomical, radiographic and x-ray (at the dorsopalmar and lateral planes) of the preparation of Manus bones. Our results showed that the large fused (third and fourth) metacarpal bones, in which the fusion extended along the entire length of the bone except at the distal end, diverged to form separate articulations with cross-ponding digits. As described in all ruminant species, especially the camel, there were two digits, and each digit consisted of three phalanges and two proximal sesamoid bones. Our radiographic x-ray data revealed that the complete radiopaque septum that completely divided the medullary cavity into two separate parts was clear from the dorsopalmar view, while the lateral view showed the proximal sesamoid bones that were placed over each other and located palmar to the head of the large metacarpal bone. In conclusion, our study reveals the adaptations of the Arabian one-humped camel to Egyptian conditions, aiding in the early diagnosis of lameness and digit problems and enabling veterinarians and camel owners to better address these issues, thereby improving the overall health and well-being of these animals.
本研究旨在分析南部阿斯旺适应型阿拉伯单峰驼手的正常解剖学和影像学特征，为诊断和治疗各种疾病提供重要数据。我们的研究应用于 10 具成年雄性单峰驼（4-5 岁）的前肢尸体，通过传统技术对手掌区域的骨骼进行大体解剖学、影像学和 X 射线（背侧掌侧和侧位）检查，对手掌骨骼进行了解剖。我们的结果表明，大融合（第三和第四）掌骨，融合沿着骨头的整个长度延伸，除了远端，向形成与交叉指分开的关节。如所有反刍动物物种，特别是骆驼，有两个数字，每个数字由三个指骨和两个近端籽骨组成。我们的放射影像学 X 射线数据显示，从背侧掌侧视图可以清楚地看到完全将骨髓腔分成两个单独部分的完整不透射线隔，而侧位视图显示了位于彼此之上并位于大掌骨头部掌侧的近端籽骨。总之，我们的研究揭示了阿拉伯单峰驼对埃及条件的适应，有助于早期诊断跛行和指部问题，并使兽医和骆驼所有者能够更好地解决这些问题，从而提高这些动物的整体健康和福利。
