Morphometry of Hip Joint in German Shepherd Dogs with Hip Dysplasia vis-a-vis Normal Hip

Abstract

Background: Data on measurements of the proximal femur, acetabulum with special reference to CHD in GSD is relatively limited. The present study recorded the complete canine femoral geometry of healthy as well as dysplastic hip joint in young dogs of GSD breed. Methods: All the dogs were subjected to radiographic evaluation to measure hip joint morphometric parameters using the CARESTREAM vita flex CR system with added IMAGE SUITE software version 4.0. Result: In dogs below 6 months of age and with CHD, measurements like AW, HD were higher in CHD where as ND, FIA values were lower. AA, EAA values were higher and AHI was lower in CHD. Indices like DI and SI were higher whereas PC and NA were lower in CHD. In healthy hip, HNI and PC values were higher in male dogs where as FNALa, ND values were higher in female dogs. In CHD, FSC, HD, TW, FSD, FIA were higher in female dogs where as HAL value was higher in male dogs. In dogs between 6 to 12 months age and with CHD, FNALa, FNALb values were higher, where as AW, ND, FSD, FIA values were lower in CHD. AA, EAA values were higher, where as AHI, PC were lower in CHD. Indices like DI and SI were higher, whereas PC and NA were lower in CHD. In dogs with healthy hip, FNALa, FNALb, TW, AHI values were higher in male dogs where as AW, AHI values were higher in female dogs. In CHD, AW, TW were higher in female dogs where as HAL, FSC, ND, FSD values were higher in male dogs.
