解剖学股骨远端尾侧角是用于评估股骨角度畸形并指导其矫正的测量指标。该角度在矢状面上通过股骨全长的内外侧位X线片或股骨多平面重建图像来确定。在X线摄影中,若内侧髁外侧髁完全重叠,则认为体位摆放满意。

解剖学股骨远端尾侧角定义为股骨远端解剖轴股骨远端关节定向线之间的角。

以下数值已在健康小型犬中发表,适用于解剖学股骨远端尾侧角:

  • 玩具贵宾犬:104.3 +/- 2.1°(X线摄影)Yasukawa et al 2016

  • 玩具贵宾犬:102.9 +/- 3.2°(CT)Yasukawa et al 2016

  • 吉娃娃:103.8 +/- 2.6°(X线摄影)Phetkaew et al 2018

  • 吉娃娃:106.2 +/- 2.4°(CT)Phetkaew et al 2018

  • 各类中大型犬:90.51 +/- 6.19°(CT)Kara et al. 2018

Peterson et al 2020将解剖学股骨远端尾侧角定义为股骨远端关节定向线的垂直线,根据其定义,该垂直线与Blumensaat线重叠。所有犬的解剖学股骨远端尾侧角均为90°。
