Abstract

Specimens of Bradypus variegatus are commonly found with thoracic limbs lesions, victims of electric shock sit-ins or trampling, presenting injuries such as loss of claws and fractures, compromising their locomotion and ability to pick up their food causing the animal to die. The aim of this study was to perform a prototyping of the common sloth limb (Bradypus variegatus), using radiographic images, digital modeling software and 3D printing, for future implantation in common sloths who suffered trauma in thoracic limb. Thus, it was intended to compensate for the absence of bone structure by rapid prototyping, establishing at least the possibility of support and to obtain food.

Highlights

The number of wild animals moving to urban or urbanized areas is increasing and this occurs because of anthropic actions (CURITIBA, 2012), where, due to these factors, several biological models, including sloths, are threatened (AZARIAS et al, 2006). Because it is a species with arboreal habits, sloths are susceptible to electric shocks and, are frequent victims for veterinary intervention (PETRUCCI et al, 2009; ARAÚJO et al, 2010)
It was possible to apply some innovations, so that in the areas of health, 3D printing or rapid prototyping has been used in human medicine, veterinary medicine and dentistry, with production of biomodels (SEARS et al, 2016) and, for this, 3D printers have emerged as a favorable option for construction of complete anatomical parts, in order to establish and validate the best positioning and treatment (SHIN-WOOK et al, 2014)
Rapid prototyping is on the rise in the health area, where it has been used in human medicine, veterinary medicine, and dentistry, with production of biomodels (Sears et al 2016)

Summary

Introduction

The number of wild animals moving to urban or urbanized areas is increasing and this occurs because of anthropic actions (CURITIBA, 2012), where, due to these factors, several biological models, including sloths, are threatened (AZARIAS et al, 2006). Because it is a species with arboreal habits, sloths are susceptible to electric shocks and, are frequent victims for veterinary intervention (PETRUCCI et al, 2009; ARAÚJO et al, 2010). According to Petrucci et al (2009), Araújo et al (2010), the most common causes of veterinary interventions in these animals, when found in urban areas, are electric shocks, when, through trees, they reach high voltage poles, located on the edge of forest, becoming victims of electrical discharges, when moving through the treetops. The construction of images can be done from two distinct forms: with the use of computed tomography, using software that unites twodimensional figures formed by this methodology and transform them into 3D images (JÓIA FILHO, 2008), or with a 3D scanner, and this method is widely used for presenting good spatial resolution and being economically accessible (SCAGLIUSI, 2015)
