The aim of this study was to investigate the variability of the slope of the pelvis in different dog breeds and the correlation between pelvic slope and femoral subluxation. The sacrum-pelvis angle (SPA), the angulation between the sacrum and the axis of the ilium was created to represent the differences in the slope of the pelvis on lateral pelvic radiographs. The Norberg angle (NA) was used to quantify the femoral subluxation on hip-extended radiographs. Archived standard ventrodorsal hip radiographs and lateral lumbosacral radiographs of the same dogs were retrieved and a single observer measured the SPA and the NA in each case. A total of 180 dogs from six different breeds were sampled. The SPA varied between 40° and 71.5° and the NA between 71.2° and 113.9°. The findings indicated that there are significant individual and interbreed variations in the slope of the pelvis. However, no significant relationship between the slope of the pelvis and femoral subluxation could be identified.
本研究旨在探讨不同犬种骨盆斜率的可变性以及骨盆斜率与股骨半脱位之间的相关性。通过骶骨-骨盆角（SPA），即骶骨与髂骨轴之间的角度，来表示侧位骨盆 X 光片上骨盆斜率的差异。使用 Norberg 角（NA）来量化髋关节伸展 X 光片上的股骨半脱位。我们检索了相同犬只的存档标准背腹侧髋关节 X 光片和侧位腰骶部 X 光片，并由一名观察者在每种情况下测量 SPA 和 NA。总共从六个不同品种中采集了 180 只狗。SPA 范围为 40°至 71.5°，NA 范围为 71.2°至 113.9°。研究结果表明，骨盆斜率存在显著的个体和品种间差异。然而，骨盆斜率与股骨半脱位之间没有明显的关系。
