Plain-English summary
A study looked at how two measurements, the Norberg angle and the position of the femoral head, can help diagnose hip dysplasia in dogs. Hip dysplasia is a common joint problem that can cause pain and mobility issues. The researchers analyzed 225 X-rays and found a strong link between these measurements, which can help veterinarians classify the severity of the condition. They discovered that different scoring systems for evaluating hip dysplasia often gave similar results, which could improve how vets assess this issue in dogs.

Abstract
SummaryCanine hip dysplasia (CHD) is a locomotive-system disease in dogs, which in many countries is the target of screening programs aimed at reducing the prevalence of CHD among descendants of predisposed dog breeds. Despite the efforts to apply genetic testing or ultrasound diagnostics in diagnosing CHD (as is common in human medicine), the main diagnostic process in veterinary medicine is by radiographic examination. The main two parameters which are used in diagnosing HD are the Norberg angle (NA) and the position of femoral head centre to the dorsal acetabular edge (FHC/DAE). We examined the relationship between these two parameters in the process of the determination of CHD degree by evaluating 225 randomly selected radiographs which were made during the period from 1993 to 2008. The aim of our study was to examine the validity of these two parameters in CHD classification as used in three different classification programs. Using Pearson’s correlation coefficient, the value of which was 0.85 (p <0.05), we observed a positive correlation. Comparing the three scoring systems for CHD evaluation, we found that the final degree of CHD was similar for 78% to 85% of cases using Flückiger’s scoring system versus a modified scoring system of 5 parameters without FHC/DAE. Results were significant.
