In order to evaluate the hind limbs of caviomorph rodents a descriptive analysis of the Cuniculus paca (Linnaeus, 1766) and Hydrochoerus hydrochaeris (Linnaeus, 1766) was performed using anatomical specimens, radiography, computed tomography (CT) and full-coloured prototype models to generate bone anatomy data. The appendicular skeleton of the two largest rodents of Neotropical America was compared with the previously reported anatomical features of Rattus norvegicus (Berkenhout, 1769) and domestic Cavia porcellus (Linnaeus, 1758). The structures were analyzed macroscopically and particular findings of each species reported. Features including the presence of articular fibular projection and lunulae were observed in the stifle joint of all rodents. Imaging aided in anatomical description and, specifically in the identification of bone structures in Cuniculus paca and Hydrochoerus hydrochaeris. The imaging findings were correlated with the anatomical structures observed. The data may be used in future studies comparing these animals to other rodents and mammalian species.
为了评估豚鼠型啮齿动物的后肢，利用解剖标本、X射线摄影、计算机断层扫描（CT）和全彩原型模型对南猯（林奈，1766年）和水豚（林奈，1766年）进行了描述性分析，以生成骨骼解剖数据。将新热带界美洲最大的两种啮齿动物的附肢骨骼与先前报道的褐家鼠（伯克霍特，1769年）和家养豚鼠（林奈，1758年）的解剖特征进行了比较。对这些结构进行了宏观分析，并报告了每个物种的具体发现。在所有啮齿动物的膝关节中均观察到包括关节腓骨突起和小半月面在内的特征。成像有助于解剖学描述，特别是在识别南猯和水豚的骨骼结构方面。成像结果与观察到的解剖结构相关。这些数据可用于未来将这些动物与其他啮齿动物和哺乳动物物种进行比较的研究。
