Quantificação e qualificação de fraturas em pelve através da radiografia padronizada e oblíqua bilateral em cães e gatos politraumatizados

Abstract

The objective of this study was to radiograph by the standardized technique (lateral-lateral and ventral-dorsal) in polytraumatized dog and cat and to compare with a bilateral oblique technique (ventral-45 medial lateral flexion left / right lateral dorsum) in the evaluation of fractures (complete and incomplete) and dislocations (sacroiliac and coxofemoral). There were evaluated eight cats and four dogs of varying age, breed and weight. After exposure of the radiographs, images were evaluated by two radiologists, control group, two orthopedists, two diagnostic imaging residents and two students. Radiographic images were distributed and evaluated at random. The analysis performed was a comparison of media for nonparametric data using a GLM, taking into account the WALD statistic and p<0.05. When comparing the total number of complete and incomplete fractures in the ventral-dorsal (VD), lateral-lateral (LL) and oblique (OBL) projections, the statistical difference between three LL, VD and OBL projections (N = 288, df = 2 , wald = 24.7 p = 0.0000) between VD and OBL (N = 288, df = 2, wald = 11.9 p = 0.0005) between LL and OBL (N = 288, df = 2 , wald = 24.0, p = 0.000001) demonstrating that the projection in the most visible fractures was a RV (n = 188). The OBL (n = 174) and RV (n = 188) projections made more visible than LL (n = 105). For evaluation of sacroiliac dislocations verified as RV (n = 33) and OBL (n = 33) projections were more frequent when compared to an LL (n = 0) (N = 288, df = 2, Wald = 1964,2). , P0.01-10). In general, as abnormalities (fractures and dislocations) were seen more accurately in RV view (n = 237), followed by OBL view (n = 225) (N = 288, df = 2, Wald = 18.1, p = 0.00002) and LL (n = 120) (N = 288, df = 2, Wald = 40.2, P˂0.01-10) suggesting that the LL project has little sensitivity in evaluating pelvic abnormalities of polytraumatized dogs and cats. However, it suggests that OBL projections should be included in pelvis studies, while LL projections should be performed in cases of conditions in the lumbosacral region
