Background: Hip dysplasia is a disease characterized by laxity of the joint and subsequent development of osteoarthritis.Pain is initially caused by joint looseness and instability. Dorsal acetabular denervation surgery have been used with ananalgesic objective. The technique initially proposed was modified, by performing a larger area of denervation. There areno studies referring to the pain parameters accepted by researchers regarding the assessment of this technique are availablein the literature. The aim of this research was express by cortisol and serum glycemia levels, the remission of pain in thepatients submitted to acetabular denervation.Materials, Methods & Results: The serum levels of cortisol and glycemia were analyzed in 11 dogs with hip dysplasiaat moments 0 (M0), I (M1), II (M2) and III (M3), which were respectively the moment of the diagnosis, 2, 7 and 15 daysafter the surgical procedure. All the patients were sumitted to the surgical intervention called dorsal acetabular denervation.The colorimetric enzymatic method was used for glucose measurement and the reading was performed using a spectrumphotometer. For the serum measurement of cortisol the ELISA method was used. The statistical analyses were processedwith the help of a computerized statistical program (Minitab Release 13). The final data obtained were analyzed regardingtheir parametric distribution using the Kolmogorov-Smirnov test. The analyzed data presented a parametric distributionand had means compared by the Tukey’s analysis of variance. Differences with P values equal or smaller than 0.05 wereconsidered significant. The correlation between the glycemia and serum cortisol values was evaluated by the Pearson test.The statistical analysis of the results points out a significant difference regarding the cortisol levels (μg/dL) at moments M1and M2 regarding the moment M0, and at moment M3 regarding the other moments. There was no significant statistical...(AU)
