Background: Fractures and dislocations are common orthopedic conditions arising from traumas from anthropic interaction on wild species, such as those caused by road trampling, being the mandibular separation with great frequency of occurrence in dogs and cats. The procedures for mandibular symphysis stabilization are described as of low complexity in the literature, however no reports of this procedure in wild canids were found. The purpose of this study is to report a surgical procedure of mandibular symphysis disjunction stabilization in an individual of the species Cerdocyon thous (crab-eating fox) through the technique of cerclage fixation using stainless steel wire.Case: An adult male individual of the free-living specie weighing 5.6 kg was referred to veterinary care after having been run-over. General physical examination showed abrasions in the ventral region of the jaw, discreet bleeding in the oral cavity, and mandibular instability. Subsequently, the patient underwent radiographic examination that revealed mandibular disjunction. The patient was therefore referred to the surgical unit for stabilization. During surgical anesthesia, two 12-gauge hypodermic needles (40x12 mm) were inserted percutaneously through the ventral region of the mandible, protruding into the oral cavity immediately caudal to the canine teeth. Next, both extremities of a 0.5 mm stainless steel wire were introduced into the interior of the needles and, when both ends extruded through the other end of the needles, the latter were removed, leaving only the steel wire uniting both rostral rami of the mandible. Using a twisting apparatus, the steel wire was twisted until the disjunction was completely stabilized and mandibular occlusion was deemed appropriate. Lastly, the surplus steel wire was sectioned, leaving a small segment that remained exposed to surface in the ventral region of the mandible.[...]
