Nowadays are observed an increase in the finding of certain wild animals in urban areas, dueto environmental changes caused by deforestation and economic use of natural areas. It causesdisappearance of usual prey and forces these animals, including snakes, to migrate to urban areas,becoming vulnerable to injuries caused by aggressions, car accidents and capture. Mandibular andmaxillar fractures are common in many animal species, representing about 3-6% of all bone fracturesin dogs and cats. Mandibular trauma usually occurs as a result of fights, car accidents and improperhandling and/or restraint, and fractures can be closed or open, clean or contaminated. The jaw is aflat bone with differences from the long bones that should be taken into consideration for successfultreatment, being minimal muscle coverage and need to maintain occlusion factors that influence thedefinition of the best ostheosynthesis method. The methods of stabilization include using intramedullarypins, wires, external skeletal fixation, bone plate, and acrylic resin. Conventional bone plates are efficientbut related to some complications, such as the necessity of muscular elevation and high risk of injuriesto mandibular structures. This article describes the successful results of the application of plate andscrews in the ostheosynthesis of a mandibular fracture in a female Boa constrictor snake with weight of8.0 kg and length of 1.80 m, at the RIOZOO Foundation (Rio de Janeiro, RJ, Brazil).(AU)
