Background: The Brazilian fox (Pseudalopex vetulus, Lund 1842) is a naturally endemic specie of the Brazilian savanna vegetation. Due to the rapid destruction of its habitat, the specie is considered vulnerable and subject to different kinds of trauma that usually results in fractures and dislocations. Among the methods of fractures fixation, highlights the external skeletal fixator intramedullary pin tie-in which consists of the intramedullary pin associated to the external fixator. The aim of the present report was to describe the case of a Brazilian fox with a comminuted tibial fracture, submitted to osteosynthesis using an external skeletal fixator intramedullary pin tie-in. Case: It was attended an exemplar of Pseudalopex vetulus, male, young adult, with 3.9 kg body weight and history of functional impotence of the left hindlimb. At the physical and orthopedic evaluations were observed loss of bone continuity and crepitus in tibial region, and the presence of a contaminated lacerating skin wound about 3 cm in diameter in the lateral side of the injured limb. Craniocaudal and mediolateral radiographic projections of the left hindlimb revealed the presence of a complete comminuted fracture at the proximal and distal shaft of the left tibia; and a complete transverse fracture at mid shaft of the left fibula. Due to this, the animal was submitted to fracture fixation [...](AU)
