股骨机械外侧近端角（mLPFA）是用于评估股骨角度畸形并指导矫正的测量指标，通过股骨X线片及多平面重建图像获得。

X线摄影时，犬取背卧位，后肢向尾侧伸展，两侧股骨相互平行。若满足以下条件，则认为体位摆放合格：

以下为已发表的股骨近端外侧机械角参考值：

  • 拉布拉多寻回犬 100 +/- 6.0°（X线片）Tomlinson et al. 2007

  • 金毛寻回犬 95 +/- 5.2°（X线片）Tomlinson et al. 2007

  • 德国牧羊犬 97 +/- 4.5°（X线片）Tomlinson et al. 2007

  • 罗威纳犬 93 +/- 4.7°（X线片）Tomlinson et al. 2007

  • 小型犬 105.1 +/- 4.6°（X线片）Olimpo et al. 2016

  • 小型犬 107°（90-127）（X线片）Garnoeva et al. 2018

  • 玩具贵宾犬 102.1 +/- 8.8°（X线片）Yasukawa et al. 2016

  • 玩具贵宾犬 113.6 +/- 6.1°（CT）Yasukawa et al. 2016

  • 英国斗牛犬 111.02 +/- 6.90°（CT）Lusetti et al. 2017

  • 吉娃娃 109.9 +/- 7.9°（X线片 CrCd位）108.5 +/- 8.2°（X线片 CdCr位）Phetkaew et al. 2018

  • 吉娃娃 120 +/- 7.1°（CT）Phetkaew et al. CT 2018
