Caracterização do recebimento de jabutis-piranga (Chelonoidis carbonaria) pelo centro de triagem de animais silvestres de Pernambuco de 2016 a 2020 e desenvolvimento de prótese 3d para lesões traumáticas de carapaça

Abstract

The objective was to characterize the red-footed tortoises (Chelonoidis carbonaria) population received by the Pernambuco Wild Animal Screening Center in the period from 2016 to 2020. The survey resulted in 1,374 cataloged animals, mostly from the Metropolitan Region of Recife, Pernambuco State, Brazil, through voluntary surrender of individuals. Of these, 531 (n=38.6%) were in captivity, with inadequate handling, resulting in poor clinical conditions. Of the 132 (9.6%) hospitalized animals, 41.6% (n=55) had traumatic injuries, where the attack by other animals corresponds to 38.2% (n=21) of the cause of origin. These attacks are also identified as the most frequent reason for the death of these individuals within CETAS during this period. In view of these data, it is possible to plan inspection and educational actions aimed at raising awareness among the population, especially in the Metropolitan Region of Recife, about the importance of preserving animals and the consequences of inadequate captive management, highlighting the role of CETAS in this scenario, encouraging the delivery of animals, so that they can be rehabilitated and returned to nature. Among the animals received, a red-footed tortoise (Chelonoidis carbonaria), female, adult, with a history of burns after a fire in a cane field was rescued and sent to the Wild Animal Screening Center of Pernambuco. The animal had carapace lesions and loss of corneal and bone plaques. Aiming to protect the animal until its recovery, the goal of the study was to build a 3D full-shell prosthesis, discussing the methodology and its adaptations, thus allowing it to be applied by other veterinarians. For 3D modeling, images of the animal were obtained by photogrammetry, these were treated by the software Regard3D 0.95 and Blender 2.78, and the final file was exported to MatterControl for printing. Polylactic acid was used as material, and the final prosthesis was finished in acrylic resin mimicking the camouflage of these animals. It can be said that the prosthesis was efficient and fulfilled the requirements by providing protection to the corneal plate bed until healing. The methodology used requires basic knowledge of the tools for the 3D modeling stage, and familiarity with the materials used in the finishing of the hull, advising the formation of a multidisciplinary team in these cases.
