Currently, the Patagonian huemul (Hippocamelus bisulcus) is endangered. Anatomical studies focused on understanding the anatomy of the deer most threatened by extinction in South America is a challenge for anatomists, veterinarians and biologists. Research carried out for its conservation has focused mainly on its ecology and pathology, leaving gaps in anatomical knowledge, which is basic and important for a comprehensive understanding of this species. Gross anatomy and radiography of the skeleton of the pelvic limb was performed in three adult Patagonian huemul. Bone specimens of three skeletally mature Patagonian huemul deer were used for gross osteological and radiographic studies. This study was conducted to reveal the morphometric and morphological features of the ossa membri pelvini of the Patagonian huemul. The main findings suggest the presence of powerful extensor muscles in the coxofemoral, femorotibial and tarsal joints, useful during walking, jogging and propulsion in deer. In general, the MNF of Patagonian huemul differ in position with respect to domestic ungulates. In addition, the presence of a notch or obturator canal was observed, with variability in morphology and development among the specimens.
