| Resumo: |
In the present study, 22 hip joints of Whippet (four), Rottweiler (five) and Labrador Retriever (two) young dogs were evaluated with the aim of comparing the ultrasonic examination of coxofemoral joints with the radiographic evaluations, both distraction and conventional procedures, for the early diagnosis of passive laxity. The study was based on static ultrasonography, conventional radiography (CR) and distraction radiography (DR) methods. In order to quantify the relationship between the femur head and the acetabulum, the alpha (alpha) and gamma (gamma) angles were measured by ultrasonographic examination, the Norberg angle (NA) was measured by CR, and the distraction index (DI) was measured by DR. It was observed a negative correlation between angles alpha and gamma (r= -0,756; P<0.001) and correlation between DI and NA (r= -0.474; P<0.026). No correlation was observed between angles alpha and gamma in relation to DI and NA (alpha and DI: r= -0.380; P<0.081; alpha and NA: r= 0.013; P<0.954; gamma and DI: r= 0.338; P<0.124; gamma and NA: r= -0.192; P<0.391). The static ultrasonographic did not prove to be a sensitive method to earlier detection of passive laxity of coxofemoral joints in dogs aging 14 and 15 day-old. The distraction index of DR was efficient in early detecting the passive laxity in dogs averaging five months old, when compared to the NA of CR. Two false negative dogs were detected by the DI. The CR method was relevant to detect osteoarthritis alterations, helping the diagnosis of hip dysplasia (HD).
