Abstract

This study was carried out to estimate the range of the hip score with 3 radiographic evaluation techniques and to identify the relationship among these methods in 71 Sapsarees (35 males and 36 females). Mean age of dogs was ranged from 4 to 73 months (averaged $24{\pm}18$ months). Hip joints were evaluated with OFA method, BVA/KC scoring scheme, and $PennHIP^{(R)}$ method. Hip joints were graded by the OFA grading system(only used for dogs over 24 month old age). The 64 joints evaluated were graded as good (17.2%), fair (46.9%), mild dysplastic (12.5%), moderate dysplastic (7.8%), and severe dysplastic (15.6%), respectively. In BVA/KC scoring scheme, the mean score of the 86 joints was recorded as $14.5{\pm}12.8$ (range from 2 to 52). The mean of Norberg angle in the 78 joints was $92.5{\pm}8.5$ degree (ranged from 63 to 110.5 degree). In $PennHIP^{(R)}$ method on the 126 joints, the mean DI was resulted as $0.60{\pm}0.16$ (ranged from 0.08 to 1.0). BVA/KC scores were gradually increased with age, positively correlated with OFA grade (r = 0.92, P < 0.001), but inversely proportional to Norberg angle (r = -0.79, P < 0.001). However, there was no correlation between BVA/KC and DI (r = 0.11). It was suggested that Sapsarees have high prevalence of cannine hip dysplasia, so selective breeding among sapsarees having normal hip joints might be necessary for preventing or controlling hip dysplasia.
