SUTURA ÍLIO-TROCANTÉRICA EM LOBO-GUARÁ: relato de caso

Abstract

The maned wolf (Chrysocyon brachyurus) is considered the largest mammal canid in South America, has a body mass between 20 and 33 kg, and can reach up to 90 cm in height. They are omnivorous animals characteristic of the Cerrado biome, but because they inhabit a wide variety of vegetation formations, they are found in all biomes in Brazil. The species has been suffering several threats related mainly to its natural habitat, due to different anthropogenic land uses. Anthropogenic changes, such as the disorderly growth of urban centers, agriculture and the consequent loss and alteration of habitat are causing a drastic reduction in ideal environments for the maintenance of wild animal populations. Roads are the main factors that not only fragment the landscape, but also generate chemical and physical impacts and, most importantly, pedestrians, generating “avoidance and barrier effects”. The avoidance effect is recurrent to the noise of cars and the barrier effect, the obstacles generated by them, making people run over. Traumatic hip dislocations are orthopedic injuries commonly observed in the routine of the surgical clinic in companion animals such as dogs and cats, and their main occurrence factor is car accidents. The aim of this study is to report a clinical case of the surgical technique iliotrochanteric suture with 5.0 nylon thread for stabilization of traumatic coxofemoral dislocation in a maned wolf. A young male maned wolf, weighing 20.9 kg, was taken to Zoovet – Clinic and Consultancy of Belo Horizonte - MG, victim of being run over on the highway. Upon his arrival, he applied pain medication (Tramadol and Gabapentin), antibiotic (Enrofloxacin and Metronidazol), vitamin supplement (HepVet), anti-inflammatory (Carprofen and Meloxicam), antiparasitic (Ivermectin) and for sedation, ketamine was used, xylazine, together with the removal of blood for the blood count, biochemical and hemoparasitic exam. As a complementary exam, radiography was requested, performed in four projections, namely the ventrodorsal, lateral-lateral, mediolateral and craniocaudal regions of the spine (lumbosacral segment), coxofemoral and left pelvic limb. After being diagnosed with hip dislocation with dislocation of the femoral head, surgical treatment was instituted using the iliotrochanteric suture technique. The use of the iliotrochanteric suture technique with non-absorbable thread was efficient in the treatment of hip dislocation in the patient in the present report, with return of limb functionality and regression of clinical signs after months of treatment, being taken to a rehabilitation center for full recovery of limb mobility and thus being released back into its natural habitat.
