Abstract：
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.
摘要：
这项研究的目的是研究不同品种狗的骨盆斜率的变异性以及骨盆斜率与股骨半脱位之间的相关性。骶骨-骨盆角（SPA），骶骨和髂骨轴之间的角度被创建来代表骨盆外侧X线照片上骨盆斜率的差异。Norberg角（NA）用于量化髋关节扩展X射线照片上的股骨半脱位。检索了同一只狗的存档的标准腹背髋部X光片和腰骶部X光片，并在每种情况下由一名观察者测量SPA和NA。对来自六个不同品种的总共180只狗进行取样。SPA在40°和71.5°之间变化,NA在71.2°和113.9°之间变化。研究结果表明，骨盆坡度存在显着的个体和杂种差异。然而,无法确定骨盆斜率与股骨半脱位之间的显着关系。
