Abstract

Objectives: To quantify lateral and dorsal acetabular femoral head (AFH) coverage in normal coxofemoral joint of Labrador retrievers and to evaluate the degree of steepness of the cranial acetabular edge (acetabular slope ‘AS' angle) and inclination angle (IA) in normal hips.
Methods: The investigated group was categorized as normal coxofemoral joints according to the morphometric criteria established by the FCI system. Centre-edge (CE) angle, Norberg angle (NA), indices of dorsal AFH coverage width and area, acetabular index angle, and inclination angle were determined. Mean (±SD) values related to all parameters were calculated. A spearman cor‌relation coefficient determined the relationship between selected variables .
Results: Significant correlations were identified between NA and CE-angle (rs= 0.58, P< 0.0001), and between the width and area of dorsal AFH coverage (rs= 0.86, P< 0.0001). Weak correlations were determined between the radiographic techniques used to assess lateral versus dorsal AFH coverage. A weak negative correlation (rs = -0.48, P < 0.0001) was determined between acetabular slope (AS) angle and CE angle. Inclination angle did not correlate with any of other radiographic measurements reported in our study.
Conclusions: The present study concluded that, radiographic evaluation of dorsal AFH coverage width and area index, CE-angle and IA (Inclination angle) during selective breeding reduce the prevalence of CHD among offspring. Coxofemoral joints with dorsal AFH coverage width index ≥ 55%, area index ≥ 59%, CE-angle ≥ 27o and IA ranges between 130o-132o are expected to be perfectly normal.
